Summary
ssl3_get_record in s3_pkt.c for OpenSSL before 0.9.7a and 0.9.6 before 0.9.6i does not perform a MAC computation if an incorrect block cipher padding is used, which causes an information leak (timing discrepancy) that may make it easier to launch cryptographic attacks that rely on distinguishing between padding and MAC verification errors, possibly leading to extraction of the original plaintext, aka the "Vaudenay timing attack."

Summary
Red Hat Security Advisory: : Updated OpenSSL packages fix timing attack
Notes
Topic
Updated OpenSSL packages are available that fix a potential timing-based
attack.
Details
OpenSSL is a commercial-grade, full-featured, and open source toolkit that
implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer
Security (TLS v1) protocols as well as a full-strength general purpose
cryptography library.
In a paper, Brice Canvel, Alain Hiltgen, Serge Vaudenay, and Martin
Vuagnoux describe and demonstrate a timing-based attack on CBC ciphersuites
in SSL and TLS. An active attacker may be able to use timing observations
to distinguish between two different error cases: cipher padding errors and
MAC verification errors. Over multiple connections this can leak
sufficient information to make it possible to retrieve the plaintext of a
common, fixed block.
In order for an attack to be sucessful, an attacker must be able to act as
a man-in-the-middle to intercept and modify multiple connections, which all
involve a common fixed plaintext block (such as a password), and have good
network conditions that allow small changes in timing to be reliably
observed.
These erratum packages contain a patch provided by the OpenSSL group that
corrects this vulnerability.
Because server applications are affected by these vulnerabilities, we
advise users to restart all services that use OpenSSL functionality or
alternatively reboot their systems after installing these updates.

Summary
Red Hat Security Advisory: apache, openssl, php security update for Stronghold
Notes
Topic
Updated versions of Stronghold 3.0 are available to fix a number of
vulnerabilities in OpenSSL, Apache, and PHP.
Details
Stronghold 3.0 contains a number of open source technologies such as
OpenSSL, Apache, and PHP. The following paragraphs describe a number of
issues that have been found in versions of these projects.
In a paper, Brice Canvel, Alain Hiltgen, Serge Vaudenay, and Martin
Vuagnoux describe and demonstrate a timing-based attack on CBC ciphersuites
in SSL and TLS. An active attacker may be able to use timing observations
to distinguish between two different error cases: cipher padding errors and
MAC verification errors. Over multiple connections this can leak
sufficient information to be able to retrieve the plain text of a common,
fixed block. In order for an attack to be successful an attacker must be
able to act as a man-in-the-middle to intercept and modify multiple
connections which all involve a common fixed plain text block (such as a
password), and have good network conditions that allow small changes in
timing to be reliably observed.
The SSL timing attack announced recently by David Brumly and Dan Boneh
is not fixed by this erratum; this new issue will be addressed by a
future erratum release.
The Apache Web server does not prevent escape sequences from being written
to log files. This could allow an attacker to embed arbitrary escape
sequences into log files. A recent paper by HD Moore highlighted
several issues where common terminal emulator software (such as xterm) can
be remotely abused or exploited by displaying arbitrary escape sequences.
The MySQL client library (libmysqlclient) used in the PHP MySQL extension
in PHP versions earlier than 4.3.0 does not properly verify length fields
for certain responses in the read_rows or read_one_row routines, which
allows a malicious server to cause a denial of service and possibly execute
arbitrary code.
Stronghold 3.0 contains OpenSSL 0.9.6b, Apache 1.3.22, and PHP
4.1.2 and is, therefore, vulnerable to these issues. Users of Stronghold are
advised to update to the errata versions of Stronghold 3.0 which contain
backported security fixes and are not vulnerable to these issues.

Summary
Red Hat Security Advisory: : Updated OpenSSL packages fix timing attack
Notes
Topic
Updated OpenSSL packages are available that fix a potential timing-based
attack.
Details
OpenSSL is a commercial-grade, full-featured, and open source toolkit that
implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer
Security (TLS v1) protocols as well as a full-strength general purpose
cryptography library.
In a paper, Brice Canvel, Alain Hiltgen, Serge Vaudenay, and Martin
Vuagnoux describe and demonstrate a timing-based attack on CBC ciphersuites
in SSL and TLS. An active attacker may be able to use timing observations
to distinguish between two different error cases: cipher padding errors and
MAC verification errors. Over multiple connections this can leak
sufficient information to make it possible to retrieve the plaintext of a
common, fixed block.
In order for an attack to be sucessful, an attacker must be able to act as
a man-in-the-middle to intercept and modify multiple connections, which all
involve a common fixed plaintext block (such as a password), and have good
network conditions that allow small changes in timing to be reliably
observed.
These erratum packages contain a patch provided by the OpenSSL group that
corrects this vulnerability.
Because server applications are affected by these vulnerabilities, we
advise users to restart all services that use OpenSSL functionality or
alternatively reboot their systems after installing these updates.

Summary
Red Hat Security Advisory: openssl security update
Notes
Topic
Updated OpenSSL packages are available that fix a potential timing-based
attack.
[Updated 12 March 2003]
Added packages for Red Hat Enterprise Linux ES and Red Hat Enterprise
Linux WS
Details
OpenSSL is a commercial-grade, full-featured, open source toolkit which
implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer
Security (TLS v1) protocols as well as a full-strength, general purpose
cryptography library.
In a paper, Brice Canvel, Alain Hiltgen, Serge Vaudenay, and Martin
Vuagnoux describe and demonstrate a timing-based attack on CBC ciphersuites
in SSL and TLS. An active attacker may be able to use timing observations
to distinguish between two different error cases: cipher padding errors and
MAC verification errors. Over multiple connections this can leak
sufficient information to be able to retrieve the plaintext of a common,
fixed block.
In order for an attack to be sucessful an attacker must be able to act as a
man-in-the-middle to intercept and modify multiple connections which all
involve a common fixed plaintext block (such as a password), and have good
network conditions that allow small changes in timing to be reliably observed.
These updated packages contain a patch provided by the OpenSSL group that
corrects this vulnerability.
Because server applications are affected by these vulnerabilities, we
advise users to restart all services that use OpenSSL functionality or
alternatively reboot their systems after installing these updates.

Summary
Red Hat Security Advisory: : : : Updated OpenSSL packages fix vulnerabilities
Notes
Topic
Updated OpenSSL packages that fix potential timing-based and modified
Bleichenbacher attacks are available for Red Hat Linux on IBM iSeries and
pSeries systems.
Details
OpenSSL is a commercial-grade, full-featured, and open source toolkit that
implements Secure Sockets Layer (SSL v2/v3) and Transport Layer
Security (TLS v1) protocols as well as a full-strength general purpose
cryptography library.
In a paper, Brice Canvel, Alain Hiltgen, Serge Vaudenay, and Martin
Vuagnoux describe and demonstrate a timing-based attack on CBC ciphersuites
in SSL and TLS. An active attacker may be able to use timing observations
to distinguish between two different error cases: cipher padding errors and
MAC verification errors. Over multiple connections this can leak
sufficient information to make it possible to retrieve the plaintext of a
common, fixed block.
In order for an attack to be sucessful, an attacker must be able to act as
a man-in-the-middle to intercept and modify multiple connections, which all
involve a common fixed plaintext block (such as a password), and have good
network conditions that allow small changes in timing to be reliably
observed.
Researchers discovered a timing attack on RSA keys. Applications making
use of OpenSSL are generally vulnerable to such an attack, unless RSA
blinding has been turned on. OpenSSL does not use RSA blinding by default
and most applications do not enable RSA blinding.
A local or remote attacker could use this attack to obtain the server's
private key by determining factors using timing differences on (1) the
number of extra reductions during Montgomery reduction, and (2) the use of
different integer multiplication algorithms ("Karatsuba" and normal).
In order for an attack to be sucessful, an attacker must have good
network conditions allowing small changes in timing to be reliably
observed.
Additionally, the SSL and TLS components for OpenSSL allow remote attackers
to perform an unauthorized RSA private key operation via a modified
Bleichenbacher attack. This attack uses a large number of SSL or TLS
connections, using PKCS #1 v1.5 padding, and causes OpenSSL to leak
information regarding the relationship between ciphertext and the
associated plaintext, aka the "Klima-Pokorny-Rosa attack."
These erratum packages contain patches provided by the OpenSSL group that
enable RSA blinding by default and protect against the other vulnerabilities.
Because server applications are affected by these vulnerabilities, users
are advised to restart all services that use OpenSSL functionality, or
reboot their systems after installing these updates.

Summary
Red Hat Security Advisory: : : : Updated OpenSSL packages fix vulnerabilities
Notes
Topic
Updated OpenSSL packages that fix potential timing-based and modified
Bleichenbacher attacks are available for Red Hat Linux on IBM iSeries and
pSeries systems.
Details
OpenSSL is a commercial-grade, full-featured, and open source toolkit that
implements Secure Sockets Layer (SSL v2/v3) and Transport Layer
Security (TLS v1) protocols as well as a full-strength general purpose
cryptography library.
In a paper, Brice Canvel, Alain Hiltgen, Serge Vaudenay, and Martin
Vuagnoux describe and demonstrate a timing-based attack on CBC ciphersuites
in SSL and TLS. An active attacker may be able to use timing observations
to distinguish between two different error cases: cipher padding errors and
MAC verification errors. Over multiple connections this can leak
sufficient information to make it possible to retrieve the plaintext of a
common, fixed block.
In order for an attack to be sucessful, an attacker must be able to act as
a man-in-the-middle to intercept and modify multiple connections, which all
involve a common fixed plaintext block (such as a password), and have good
network conditions that allow small changes in timing to be reliably
observed.
Researchers discovered a timing attack on RSA keys. Applications making
use of OpenSSL are generally vulnerable to such an attack, unless RSA
blinding has been turned on. OpenSSL does not use RSA blinding by default
and most applications do not enable RSA blinding.
A local or remote attacker could use this attack to obtain the server's
private key by determining factors using timing differences on (1) the
number of extra reductions during Montgomery reduction, and (2) the use of
different integer multiplication algorithms ("Karatsuba" and normal).
In order for an attack to be sucessful, an attacker must have good
network conditions allowing small changes in timing to be reliably
observed.
Additionally, the SSL and TLS components for OpenSSL allow remote attackers
to perform an unauthorized RSA private key operation via a modified
Bleichenbacher attack. This attack uses a large number of SSL or TLS
connections, using PKCS #1 v1.5 padding, and causes OpenSSL to leak
information regarding the relationship between ciphertext and the
associated plaintext, aka the "Klima-Pokorny-Rosa attack."
These erratum packages contain patches provided by the OpenSSL group that
enable RSA blinding by default and protect against the other vulnerabilities.
Because server applications are affected by these vulnerabilities, users
are advised to restart all services that use OpenSSL functionality, or
reboot their systems after installing these updates.

Summary
Red Hat Security Advisory: apache, openssl, php, tomcat security update for Stronghold
Notes
Topic
Updated versions of Stronghold 4 cross-platform are available to fix a
number of vulnerabilities in OpenSSL, Apache, PHP, and Tomcat.
Also included in this update are bug fixes for mod_proxy and the
mod_authz_ldap package.
Details
Stronghold 4 cross platform contains a number of open source technologies
such as OpenSSL, Apache, and PHP. A number of issues have been found in
versions of these projects:
In a paper, Brice Canvel, Alain Hiltgen, Serge Vaudenay, and Martin
Vuagnoux describe and demonstrate a timing-based attack on CBC ciphersuites
in SSL and TLS. An active attacker may be able to use timing observations
to distinguish between two different error cases: cipher padding errors and
MAC verification errors. Over multiple connections this can leak
sufficient information to be able to retrieve the plain text of a common,
fixed block. In order for an attack to be successful an attacker must be
able to act as a man-in-the-middle to intercept and modify multiple
connections which all involve a common fixed plain text block (such as a
password), and have good network conditions that allow small changes in
timing to be reliably observed.
The Apache Web server does not prevent escape sequences from being written
to the error log. This could allow an attacker to embed arbitrary escape
sequences into the log file. A recent paper by HD Moore highlighted
several issues where common terminal emulator software (such as xterm) can
be remotely abused or exploited by displaying arbitrary escape sequences.
The MySQL client library (libmysqlclient) used in the PHP MySQL extension
in PHP versions earlier than 4.3.0 does not properly verify length fields
for certain responses in the read_rows or read_one_row routines, which
allows a malicious server to cause a denial of service and possibly execute
arbitrary code.
A source code exposure vulnerability has been found that affects Tomcat
versions 4.0.0 through 4.0.5 and 4.1.0 through 4.1.12, in a variant of
the issue addressed in RHSA-2002:217. Using a carefully crafted request, a
remote attacker can read the source code of any deployed JSP file.
In addition to the security fixes, two bug fixes have also been applied:
If Apache is configured to act as a reverse proxy by specifying the backend
server using a numeric IP address, the mod_proxy module will perform a
redundant reverse DNS lookup on the IP address, causing a delay in request
processing.
A bug in mod_authz_ldap version 0.21 and earlier prevent
authentication being performed by other Apache modules (such as
filed-based authentication using mod_auth) when the mod_authz_ldap module
is loaded.
Stronghold 4 cross platform contains OpenSSL 0.9.6c, Apache 1.3.22, PHP
4.1.2, Tomcat 4.0.5, and mod_authz_ldap 0.19, and is therefore vulnerable
to these issues. Users of Stronghold are advised to update to the errata
versions of Stronghold 4 which contain backported security fixes and are
not vulnerable to these issues.

Summary
Red Hat Security Advisory: openssl security update
Notes
Topic
Updated OpenSSL packages are available that fix a potential timing-based
attack.
[Updated 12 March 2003]
Added packages for Red Hat Enterprise Linux ES and Red Hat Enterprise
Linux WS
Details
OpenSSL is a commercial-grade, full-featured, open source toolkit which
implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer
Security (TLS v1) protocols as well as a full-strength, general purpose
cryptography library.
In a paper, Brice Canvel, Alain Hiltgen, Serge Vaudenay, and Martin
Vuagnoux describe and demonstrate a timing-based attack on CBC ciphersuites
in SSL and TLS. An active attacker may be able to use timing observations
to distinguish between two different error cases: cipher padding errors and
MAC verification errors. Over multiple connections this can leak
sufficient information to be able to retrieve the plaintext of a common,
fixed block.
In order for an attack to be sucessful an attacker must be able to act as a
man-in-the-middle to intercept and modify multiple connections which all
involve a common fixed plaintext block (such as a password), and have good
network conditions that allow small changes in timing to be reliably observed.
These updated packages contain a patch provided by the OpenSSL group that
corrects this vulnerability.
Because server applications are affected by these vulnerabilities, we
advise users to restart all services that use OpenSSL functionality or
alternatively reboot their systems after installing these updates.

Summary
Red Hat Security Advisory: apache, openssl, php security update for Stronghold
Notes
Topic
Updated versions of Stronghold 3.0 are available to fix a number of
vulnerabilities in OpenSSL, Apache, and PHP.
Details
Stronghold 3.0 contains a number of open source technologies such as
OpenSSL, Apache, and PHP. The following paragraphs describe a number of
issues that have been found in versions of these projects.
In a paper, Brice Canvel, Alain Hiltgen, Serge Vaudenay, and Martin
Vuagnoux describe and demonstrate a timing-based attack on CBC ciphersuites
in SSL and TLS. An active attacker may be able to use timing observations
to distinguish between two different error cases: cipher padding errors and
MAC verification errors. Over multiple connections this can leak
sufficient information to be able to retrieve the plain text of a common,
fixed block. In order for an attack to be successful an attacker must be
able to act as a man-in-the-middle to intercept and modify multiple
connections which all involve a common fixed plain text block (such as a
password), and have good network conditions that allow small changes in
timing to be reliably observed.
The SSL timing attack announced recently by David Brumly and Dan Boneh
is not fixed by this erratum; this new issue will be addressed by a
future erratum release.
The Apache Web server does not prevent escape sequences from being written
to log files. This could allow an attacker to embed arbitrary escape
sequences into log files. A recent paper by HD Moore highlighted
several issues where common terminal emulator software (such as xterm) can
be remotely abused or exploited by displaying arbitrary escape sequences.
The MySQL client library (libmysqlclient) used in the PHP MySQL extension
in PHP versions earlier than 4.3.0 does not properly verify length fields
for certain responses in the read_rows or read_one_row routines, which
allows a malicious server to cause a denial of service and possibly execute
arbitrary code.
Stronghold 3.0 contains OpenSSL 0.9.6b, Apache 1.3.22, and PHP
4.1.2 and is, therefore, vulnerable to these issues. Users of Stronghold are
advised to update to the errata versions of Stronghold 3.0 which contain
backported security fixes and are not vulnerable to these issues.

Summary
Red Hat Security Advisory: : Updated OpenSSL packages fix timing attack
Notes
Topic
Updated OpenSSL packages are available that fix a potential timing-based
attack.
Details
OpenSSL is a commercial-grade, full-featured, and open source toolkit that
implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer
Security (TLS v1) protocols as well as a full-strength general purpose
cryptography library.
In a paper, Brice Canvel, Alain Hiltgen, Serge Vaudenay, and Martin
Vuagnoux describe and demonstrate a timing-based attack on CBC ciphersuites
in SSL and TLS. An active attacker may be able to use timing observations
to distinguish between two different error cases: cipher padding errors and
MAC verification errors. Over multiple connections this can leak
sufficient information to make it possible to retrieve the plaintext of a
common, fixed block.
In order for an attack to be sucessful, an attacker must be able to act as
a man-in-the-middle to intercept and modify multiple connections, which all
involve a common fixed plaintext block (such as a password), and have good
network conditions that allow small changes in timing to be reliably
observed.
These erratum packages contain a patch provided by the OpenSSL group that
corrects this vulnerability.
Because server applications are affected by these vulnerabilities, we
advise users to restart all services that use OpenSSL functionality or
alternatively reboot their systems after installing these updates.

Summary
Red Hat Security Advisory: apache, openssl, php, tomcat security update for Stronghold
Notes
Topic
Updated versions of Stronghold 4 cross-platform are available to fix a
number of vulnerabilities in OpenSSL, Apache, PHP, and Tomcat.
Also included in this update are bug fixes for mod_proxy and the
mod_authz_ldap package.
Details
Stronghold 4 cross platform contains a number of open source technologies
such as OpenSSL, Apache, and PHP. A number of issues have been found in
versions of these projects:
In a paper, Brice Canvel, Alain Hiltgen, Serge Vaudenay, and Martin
Vuagnoux describe and demonstrate a timing-based attack on CBC ciphersuites
in SSL and TLS. An active attacker may be able to use timing observations
to distinguish between two different error cases: cipher padding errors and
MAC verification errors. Over multiple connections this can leak
sufficient information to be able to retrieve the plain text of a common,
fixed block. In order for an attack to be successful an attacker must be
able to act as a man-in-the-middle to intercept and modify multiple
connections which all involve a common fixed plain text block (such as a
password), and have good network conditions that allow small changes in
timing to be reliably observed.
The Apache Web server does not prevent escape sequences from being written
to the error log. This could allow an attacker to embed arbitrary escape
sequences into the log file. A recent paper by HD Moore highlighted
several issues where common terminal emulator software (such as xterm) can
be remotely abused or exploited by displaying arbitrary escape sequences.
The MySQL client library (libmysqlclient) used in the PHP MySQL extension
in PHP versions earlier than 4.3.0 does not properly verify length fields
for certain responses in the read_rows or read_one_row routines, which
allows a malicious server to cause a denial of service and possibly execute
arbitrary code.
A source code exposure vulnerability has been found that affects Tomcat
versions 4.0.0 through 4.0.5 and 4.1.0 through 4.1.12, in a variant of
the issue addressed in RHSA-2002:217. Using a carefully crafted request, a
remote attacker can read the source code of any deployed JSP file.
In addition to the security fixes, two bug fixes have also been applied:
If Apache is configured to act as a reverse proxy by specifying the backend
server using a numeric IP address, the mod_proxy module will perform a
redundant reverse DNS lookup on the IP address, causing a delay in request
processing.
A bug in mod_authz_ldap version 0.21 and earlier prevent
authentication being performed by other Apache modules (such as
filed-based authentication using mod_auth) when the mod_authz_ldap module
is loaded.
Stronghold 4 cross platform contains OpenSSL 0.9.6c, Apache 1.3.22, PHP
4.1.2, Tomcat 4.0.5, and mod_authz_ldap 0.19, and is therefore vulnerable
to these issues. Users of Stronghold are advised to update to the errata
versions of Stronghold 4 which contain backported security fixes and are
not vulnerable to these issues.

Summary
Red Hat Security Advisory: : : : Updated OpenSSL packages fix vulnerabilities
Notes
Topic
Updated OpenSSL packages that fix potential timing-based and modified
Bleichenbacher attacks are available for Red Hat Linux on IBM iSeries and
pSeries systems.
Details
OpenSSL is a commercial-grade, full-featured, and open source toolkit that
implements Secure Sockets Layer (SSL v2/v3) and Transport Layer
Security (TLS v1) protocols as well as a full-strength general purpose
cryptography library.
In a paper, Brice Canvel, Alain Hiltgen, Serge Vaudenay, and Martin
Vuagnoux describe and demonstrate a timing-based attack on CBC ciphersuites
in SSL and TLS. An active attacker may be able to use timing observations
to distinguish between two different error cases: cipher padding errors and
MAC verification errors. Over multiple connections this can leak
sufficient information to make it possible to retrieve the plaintext of a
common, fixed block.
In order for an attack to be sucessful, an attacker must be able to act as
a man-in-the-middle to intercept and modify multiple connections, which all
involve a common fixed plaintext block (such as a password), and have good
network conditions that allow small changes in timing to be reliably
observed.
Researchers discovered a timing attack on RSA keys. Applications making
use of OpenSSL are generally vulnerable to such an attack, unless RSA
blinding has been turned on. OpenSSL does not use RSA blinding by default
and most applications do not enable RSA blinding.
A local or remote attacker could use this attack to obtain the server's
private key by determining factors using timing differences on (1) the
number of extra reductions during Montgomery reduction, and (2) the use of
different integer multiplication algorithms ("Karatsuba" and normal).
In order for an attack to be sucessful, an attacker must have good
network conditions allowing small changes in timing to be reliably
observed.
Additionally, the SSL and TLS components for OpenSSL allow remote attackers
to perform an unauthorized RSA private key operation via a modified
Bleichenbacher attack. This attack uses a large number of SSL or TLS
connections, using PKCS #1 v1.5 padding, and causes OpenSSL to leak
information regarding the relationship between ciphertext and the
associated plaintext, aka the "Klima-Pokorny-Rosa attack."
These erratum packages contain patches provided by the OpenSSL group that
enable RSA blinding by default and protect against the other vulnerabilities.
Because server applications are affected by these vulnerabilities, users
are advised to restart all services that use OpenSSL functionality, or
reboot their systems after installing these updates.

Summary
Red Hat Security Advisory: apache, openssl, php security update for Stronghold
Notes
Topic
Updated versions of Stronghold 3.0 are available to fix a number of
vulnerabilities in OpenSSL, Apache, and PHP.
Details
Stronghold 3.0 contains a number of open source technologies such as
OpenSSL, Apache, and PHP. The following paragraphs describe a number of
issues that have been found in versions of these projects.
In a paper, Brice Canvel, Alain Hiltgen, Serge Vaudenay, and Martin
Vuagnoux describe and demonstrate a timing-based attack on CBC ciphersuites
in SSL and TLS. An active attacker may be able to use timing observations
to distinguish between two different error cases: cipher padding errors and
MAC verification errors. Over multiple connections this can leak
sufficient information to be able to retrieve the plain text of a common,
fixed block. In order for an attack to be successful an attacker must be
able to act as a man-in-the-middle to intercept and modify multiple
connections which all involve a common fixed plain text block (such as a
password), and have good network conditions that allow small changes in
timing to be reliably observed.
The SSL timing attack announced recently by David Brumly and Dan Boneh
is not fixed by this erratum; this new issue will be addressed by a
future erratum release.
The Apache Web server does not prevent escape sequences from being written
to log files. This could allow an attacker to embed arbitrary escape
sequences into log files. A recent paper by HD Moore highlighted
several issues where common terminal emulator software (such as xterm) can
be remotely abused or exploited by displaying arbitrary escape sequences.
The MySQL client library (libmysqlclient) used in the PHP MySQL extension
in PHP versions earlier than 4.3.0 does not properly verify length fields
for certain responses in the read_rows or read_one_row routines, which
allows a malicious server to cause a denial of service and possibly execute
arbitrary code.
Stronghold 3.0 contains OpenSSL 0.9.6b, Apache 1.3.22, and PHP
4.1.2 and is, therefore, vulnerable to these issues. Users of Stronghold are
advised to update to the errata versions of Stronghold 3.0 which contain
backported security fixes and are not vulnerable to these issues.

Summary
Red Hat Security Advisory: openssl security update
Notes
Topic
Updated OpenSSL packages are available that fix a potential timing-based
attack.
[Updated 12 March 2003]
Added packages for Red Hat Enterprise Linux ES and Red Hat Enterprise
Linux WS
Details
OpenSSL is a commercial-grade, full-featured, open source toolkit which
implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer
Security (TLS v1) protocols as well as a full-strength, general purpose
cryptography library.
In a paper, Brice Canvel, Alain Hiltgen, Serge Vaudenay, and Martin
Vuagnoux describe and demonstrate a timing-based attack on CBC ciphersuites
in SSL and TLS. An active attacker may be able to use timing observations
to distinguish between two different error cases: cipher padding errors and
MAC verification errors. Over multiple connections this can leak
sufficient information to be able to retrieve the plaintext of a common,
fixed block.
In order for an attack to be sucessful an attacker must be able to act as a
man-in-the-middle to intercept and modify multiple connections which all
involve a common fixed plaintext block (such as a password), and have good
network conditions that allow small changes in timing to be reliably observed.
These updated packages contain a patch provided by the OpenSSL group that
corrects this vulnerability.
Because server applications are affected by these vulnerabilities, we
advise users to restart all services that use OpenSSL functionality or
alternatively reboot their systems after installing these updates.

Summary
Red Hat Security Advisory: apache, openssl, php, tomcat security update for Stronghold
Notes
Topic
Updated versions of Stronghold 4 cross-platform are available to fix a
number of vulnerabilities in OpenSSL, Apache, PHP, and Tomcat.
Also included in this update are bug fixes for mod_proxy and the
mod_authz_ldap package.
Details
Stronghold 4 cross platform contains a number of open source technologies
such as OpenSSL, Apache, and PHP. A number of issues have been found in
versions of these projects:
In a paper, Brice Canvel, Alain Hiltgen, Serge Vaudenay, and Martin
Vuagnoux describe and demonstrate a timing-based attack on CBC ciphersuites
in SSL and TLS. An active attacker may be able to use timing observations
to distinguish between two different error cases: cipher padding errors and
MAC verification errors. Over multiple connections this can leak
sufficient information to be able to retrieve the plain text of a common,
fixed block. In order for an attack to be successful an attacker must be
able to act as a man-in-the-middle to intercept and modify multiple
connections which all involve a common fixed plain text block (such as a
password), and have good network conditions that allow small changes in
timing to be reliably observed.
The Apache Web server does not prevent escape sequences from being written
to the error log. This could allow an attacker to embed arbitrary escape
sequences into the log file. A recent paper by HD Moore highlighted
several issues where common terminal emulator software (such as xterm) can
be remotely abused or exploited by displaying arbitrary escape sequences.
The MySQL client library (libmysqlclient) used in the PHP MySQL extension
in PHP versions earlier than 4.3.0 does not properly verify length fields
for certain responses in the read_rows or read_one_row routines, which
allows a malicious server to cause a denial of service and possibly execute
arbitrary code.
A source code exposure vulnerability has been found that affects Tomcat
versions 4.0.0 through 4.0.5 and 4.1.0 through 4.1.12, in a variant of
the issue addressed in RHSA-2002:217. Using a carefully crafted request, a
remote attacker can read the source code of any deployed JSP file.
In addition to the security fixes, two bug fixes have also been applied:
If Apache is configured to act as a reverse proxy by specifying the backend
server using a numeric IP address, the mod_proxy module will perform a
redundant reverse DNS lookup on the IP address, causing a delay in request
processing.
A bug in mod_authz_ldap version 0.21 and earlier prevent
authentication being performed by other Apache modules (such as
filed-based authentication using mod_auth) when the mod_authz_ldap module
is loaded.
Stronghold 4 cross platform contains OpenSSL 0.9.6c, Apache 1.3.22, PHP
4.1.2, Tomcat 4.0.5, and mod_authz_ldap 0.19, and is therefore vulnerable
to these issues. Users of Stronghold are advised to update to the errata
versions of Stronghold 4 which contain backported security fixes and are
not vulnerable to these issues.
