ID CVE-2009-5064
Summary ** DISPUTED ** ldd in the GNU C Library (aka glibc or libc6) 2.13 and earlier allows local users to gain privileges via a Trojan horse executable file linked with a modified loader that omits certain LD_TRACE_LOADED_OBJECTS checks. NOTE: the GNU C Library vendor states "This is just nonsense. There are a gazillion other ways to introduce code if people are downloading arbitrary binaries and install them in appropriate directories or set LD_LIBRARY_PATH etc."

Impact:
Exploitability:
CWE CWE-264
CAPEC
  • Accessing, Modifying or Executing Executable Files
    An attack of this type exploits a system's configuration that allows an attacker to either directly access an executable file, for example through shell access; or in a possible worst case allows an attacker to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.
  • Leverage Executable Code in Non-Executable Files
    An attack of this type exploits a system's trust in configuration and resource files, when the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high. The attack can be directed at a client system, such as causing buffer overrun through loading seemingly benign image files, as in Microsoft Security Bulletin MS04-028 where specially crafted JPEG files could cause a buffer overrun once loaded into the browser. Another example targets clients reading pdf files. In this case the attacker simply appends javascript to the end of a legitimate url for a pdf (http://www.gnucitizen.org/blog/danger-danger-danger/) http://path/to/pdf/file.pdf#whatever_name_you_want=javascript:your_code_here The client assumes that they are reading a pdf, but the attacker has modified the resource and loaded executable javascript into the client's browser process. The attack can also target server processes. The attacker edits the resource or configuration file, for example a web.xml file used to configure security permissions for a J2EE app server, adding role name "public" grants all users with the public role the ability to use the administration functionality. The server trusts its configuration file to be correct, but when they are manipulated, the attacker gains full control.
  • Blue Boxing
    This type of attack against older telephone switches and trunks has been around for decades. A tone is sent by an adversary to impersonate a supervisor signal which has the effect of rerouting or usurping command of the line. While the US infrastructure proper may not contain widespread vulnerabilities to this type of attack, many companies are connected globally through call centers and business process outsourcing. These international systems may be operated in countries which have not upgraded Telco infrastructure and so are vulnerable to Blue boxing. Blue boxing is a result of failure on the part of the system to enforce strong authorization for administrative functions. While the infrastructure is different than standard current applications like web applications, there are historical lessons to be learned to upgrade the access control for administrative functions.
  • Restful Privilege Elevation
    Rest uses standard HTTP (Get, Put, Delete) style permissions methods, but these are not necessarily correlated generally with back end programs. Strict interpretation of HTTP get methods means that these HTTP Get services should not be used to delete information on the server, but there is no access control mechanism to back up this logic. This means that unless the services are properly ACL'd and the application's service implementation are following these guidelines then an HTTP request can easily execute a delete or update on the server side. The attacker identifies a HTTP Get URL such as http://victimsite/updateOrder, which calls out to a program to update orders on a database or other resource. The URL is not idempotent so the request can be submitted multiple times by the attacker, additionally, the attacker may be able to exploit the URL published as a Get method that actually performs updates (instead of merely retrieving data). This may result in malicious or inadvertent altering of data on the server.
  • Target Programs with Elevated Privileges
    This attack targets programs running with elevated privileges. The attacker would try to leverage a bug in the running program and get arbitrary code to execute with elevated privileges. For instance an attacker would look for programs that write to the system directories or registry keys (such as HKLM, which stores a number of critical Windows environment variables). These programs are typically running with elevated privileges and have usually not been designed with security in mind. Such programs are excellent exploit targets because they yield lots of power when they break. The malicious user try to execute its code at the same level as a privileged system call.
  • Manipulating Input to File System Calls
    An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.

    description Updated glibc packages that fix multiple security issues are now available for Red Hat Enterprise Linux 5. The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The glibc packages contain the standard C libraries used by multiple programs on the system. These packages contain the standard C and the standard math libraries. Without these two libraries, a Linux system cannot function properly. An integer overflow flaw, leading to a heap-based buffer overflow, was found in the way the glibc library read timezone files. If a carefully-crafted timezone file was loaded by an application linked against glibc, it could cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2009-5029) A flaw was found in the way the ldd utility identified dynamically linked libraries. If an attacker could trick a user into running ldd on a malicious binary, it could result in arbitrary code execution with the privileges of the user running ldd. (CVE-2009-5064) An integer overflow flaw, leading to a heap-based buffer overflow, was found in the way the glibc library loaded ELF (Executable and Linking Format) files. If a carefully-crafted ELF file was loaded by an application linked against glibc, it could cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2010-0830) It was found that the glibc addmntent() function, used by various mount helper utilities, did not handle certain errors correctly when updating the mtab (mounted file systems table) file. If such utilities had the setuid bit set, a local attacker could use this flaw to corrupt the mtab file. (CVE-2011-1089) A denial of service flaw was found in the remote procedure call (RPC) implementation in glibc. A remote attacker able to open a large number of connections to an RPC service that is using the RPC implementation from glibc, could use this flaw to make that service use an excessive amount of CPU time. (CVE-2011-4609) Red Hat would like to thank the Ubuntu Security Team for reporting CVE-2010-0830, and Dan Rosenberg for reporting CVE-2011-1089.

(CVE-2011-4577) - A denial of service vulnerability exists in the RPC implementation in the glibc library due to a flaw in the svc_run() function. A remote attacker can exploit this, via large number of RPC connections, to exhaust CPU resources. (CVE-2011-4609) - A denial of service vulnerability exists in the Server Gated Cryptography (SGC) implementation in OpenSSL due to a failure to properly handle handshake restarts. A remote attacker can exploit this, via unspecified vectors, to exhaust CPU resources. (CVE-2011-4619) - A denial of service vulnerability exists in OpenSSL due to improper support of DTLS applications. A remote attacker can exploit this, via unspecified vectors related to an out-of-bounds read error. Note that this vulnerability exists because of an incorrect fix for CVE-2011-4108. (CVE-2012-0050) - A security bypass vulnerability exists in the glibc library due to an integer overflow condition in the vfprintf() function in file stdio-common/vfprintf.c. An attacker can exploit this, by using a large number of arguments, to bypass the FORTIFY_SOURCE protection mechanism, allowing format string attacks or writing to arbitrary memory. (CVE-2012-0864) - A denial of service vulnerability exists in the glibc library in the vfprintf() function in file stdio-common/vfprintf.c due to a failure to properly calculate a buffer length. An attacker can exploit this, via a format string that uses positional parameters and many format specifiers, to bypass the FORTIFY_SOURCE format-string protection mechanism, thus causing stack corruption and a crash. (CVE-2012-3404) - A denial of service vulnerability exists in the glibc library in the vfprintf() function in file stdio-common/vfprintf.c due to a failure to properly calculate a buffer length. An attacker can exploit this, via a format string with a large number of format specifiers, to bypass the FORTIFY_SOURCE format-string protection mechanism, thus triggering desynchronization within the buffer size handling, resulting in a segmentation fault and crash. (CVE-2012-3405) - A flaw exists in the glibc library in the vfprintf() function in file stdio-common/vfprintf.c due to a failure to properly restrict the use of the alloca() function when allocating the SPECS array. An attacker can exploit this, via a crafted format string using positional parameters and a large number of format specifiers, to bypass the FORTIFY_SOURCE format-string protection mechanism, thus triggering a denial of service or the possible execution of arbitrary code. (CVE-2012-3406) - A flaw exists in the glibc library due to multiple integer overflow conditions in the strtod(), strtof(), strtold(), strtod_l(), and other unspecified related functions. A local attacker can exploit these to trigger a stack-based buffer overflow, resulting in an application crash or the possible execution of arbitrary code. (CVE-2012-3480) - A privilege escalation vulnerability exists in the Virtual Machine Communication Interface (VMCI) due to a failure by control code to properly restrict memory allocation. A local attacker can exploit this, via unspecified vectors, to gain privileges. (CVE-2013-1406) - An error exists in the implementation of the Network File Copy (NFC) protocol.

    description Updated glibc packages that fix multiple security issues and one bug are now available for Red Hat Enterprise Linux 4. The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The glibc packages contain the standard C libraries used by multiple programs on the system. These packages contain the standard C and the standard math libraries. Without these two libraries, a Linux system cannot function properly. An integer overflow flaw, leading to a heap-based buffer overflow, was found in the way the glibc library read timezone files. If a carefully-crafted timezone file was loaded by an application linked against glibc, it could cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2009-5029) A flaw was found in the way the ldd utility identified dynamically linked libraries. If an attacker could trick a user into running ldd on a malicious binary, it could result in arbitrary code execution with the privileges of the user running ldd. (CVE-2009-5064) It was discovered that the glibc addmntent() function, used by various mount helper utilities, did not sanitize its input properly. A local attacker could possibly use this flaw to inject malformed lines into the mtab (mounted file systems table) file via certain setuid mount helpers, if the attacker were allowed to mount to an arbitrary directory under their control. (CVE-2010-0296) An integer overflow flaw, leading to a heap-based buffer overflow, was found in the way the glibc library loaded ELF (Executable and Linking Format) files. If a carefully-crafted ELF file was loaded by an application linked against glibc, it could cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2010-0830) It was discovered that the glibc fnmatch() function did not properly restrict the use of alloca(). If the function was called on sufficiently large inputs, it could cause an application using fnmatch() to crash or, possibly, execute arbitrary code with the privileges of the application. (CVE-2011-1071) It was found that the glibc addmntent() function, used by various mount helper utilities, did not handle certain errors correctly when updating the mtab (mounted file systems table) file. If such utilities had the setuid bit set, a local attacker could use this flaw to corrupt the mtab file. (CVE-2011-1089) It was discovered that the locale command did not produce properly escaped output as required by the POSIX specification. If an attacker were able to set the locale environment variables in the environment of a script that performed shell evaluation on the output of the locale command, and that script were run with different privileges than the attacker's, it could execute arbitrary code with the privileges of the script. (CVE-2011-1095) An integer overflow flaw was found in the glibc fnmatch() function. If an attacker supplied a long UTF-8 string to an application linked against glibc, it could cause the application to crash. (CVE-2011-1659) A denial of service flaw was found in the remote procedure call (RPC) implementation in glibc. A remote attacker able to open a large number of connections to an RPC service that is using the RPC implementation from glibc, could use this flaw to make that service use an excessive amount of CPU time. (CVE-2011-4609) Red Hat would like to thank the Ubuntu Security Team for reporting CVE-2010-0830, and Dan Rosenberg for reporting CVE-2011-1089. The Ubuntu Security Team acknowledges Dan Rosenberg as the original reporter of CVE-2010-0830. This update also fixes the following bug : * When using an nscd package that is a different version than the glibc package, the nscd service could fail to start. This update makes the nscd package require a specific glibc version to prevent this problem. (BZ#657009) Users should upgrade to these updated packages, which resolve these issues.

    description An updated rhev-hypervisor5 package that fixes several security issues and various bugs is now available. The Red Hat Security Response Team has rated this update as having important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The rhev-hypervisor5 package provides a Red Hat Enterprise Virtualization Hypervisor ISO disk image. The Red Hat Enterprise Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine (KVM) hypervisor. It includes everything necessary to run and manage virtual machines: A subset of the Red Hat Enterprise Linux operating environment and the Red Hat Enterprise Virtualization Agent. Note: Red Hat Enterprise Virtualization Hypervisor is only available for the Intel 64 and AMD64 architectures with virtualization extensions. A heap overflow flaw was found in the way QEMU-KVM emulated the e1000 network interface card. A privileged guest user in a virtual machine whose network interface is configured to use the e1000 emulated driver could use this flaw to crash the host or, possibly, escalate their privileges on the host. (CVE-2012-0029) A divide-by-zero flaw was found in the Linux kernel's igmp_heard_query() function. An attacker able to send certain IGMP (Internet Group Management Protocol) packets to a target system could use this flaw to cause a denial of service. (CVE-2012-0207) A double free flaw was discovered in the policy checking code in OpenSSL. A remote attacker could use this flaw to crash an application that uses OpenSSL by providing an X.509 certificate that has specially crafted policy extension data. (CVE-2011-4109) An information leak flaw was found in the SSL 3.0 protocol implementation in OpenSSL. Incorrect initialization of SSL record padding bytes could cause an SSL client or server to send a limited amount of possibly sensitive data to its SSL peer via the encrypted connection. (CVE-2011-4576) It was discovered that OpenSSL did not limit the number of TLS/SSL handshake restarts required to support Server Gated Cryptography. A remote attacker could use this flaw to make a TLS/SSL server using OpenSSL consume an excessive amount of CPU by continuously restarting the handshake. (CVE-2011-4619) Red Hat would like to thank Nicolae Mogoreanu for reporting CVE-2012-0029, and Simon McVittie for reporting CVE-2012-0207. This updated package provides updated components that include fixes for various security issues. These issues have no security impact on Red Hat Enterprise Virtualization Hypervisor itself, however. The security fixes included in this update address the following CVE numbers : CVE-2006-1168 and CVE-2011-2716 (busybox issues) CVE-2009-5029, CVE-2009-5064, CVE-2010-0830 and CVE-2011-1089 (glibc issues) CVE-2011-1083, CVE-2011-3638, CVE-2011-4086, CVE-2011-4127 and CVE-2012-0028 (kernel issues) CVE-2011-1526 (krb5 issue) CVE-2011-4347 (kvm issue) CVE-2010-4008, CVE-2011-0216, CVE-2011-2834, CVE-2011-3905, CVE-2011-3919 and CVE-2011-1944 (libxml2 issues) CVE-2011-1749 (nfs-utils issue) CVE-2011-4108 (openssl issue) CVE-2011-0010 (sudo issue) CVE-2011-1675 and CVE-2011-1677 (util-linux issues) CVE-2010-0424 (vixie-cron issue) This updated rhev-hypervisor5 package fixes various bugs. Documentation of these changes will be available shortly in the Technical Notes document : https://docs.redhat.com/docs/en-US/ Red_Hat_Enterprise_Virtualization_for_Servers/2.2/html/Technical_Notes / index.html Users of Red Hat Enterprise Virtualization Hypervisor are advised to upgrade to this updated package, which fixes these issues.

If an attacker were able to set the locale environment variables in the environment of a script that performed shell evaluation on the output of the locale command, and that script were run with different privileges than the attacker's, it could execute arbitrary code with the privileges of the script. (CVE-2011-1095) An integer overflow flaw was found in the glibc fnmatch() function. If an attacker supplied a long UTF-8 string to an application linked against glibc, it could cause the application to crash. (CVE-2011-1659) A denial of service flaw was found in the remote procedure call (RPC) implementation in glibc. A remote attacker able to open a large number of connections to an RPC service that is using the RPC implementation from glibc, could use this flaw to make that service use an excessive amount of CPU time. (CVE-2011-4609) Red Hat would like to thank the Ubuntu Security Team for reporting CVE-2010-0830, and Dan Rosenberg for reporting CVE-2011-1089. The Ubuntu Security Team acknowledges Dan Rosenberg as the original reporter of CVE-2010-0830. This update also fixes the following bug : * When using an nscd package that is a different version than the glibc package, the nscd service could fail to start. This update makes the nscd package require a specific glibc version to prevent this problem. (BZ#657009) Users should upgrade to these updated packages, which resolve these issues.

    description The glibc packages contain the standard C libraries used by multiple programs on the system. These packages contain the standard C and the standard math libraries. Without these two libraries, a Linux system cannot function properly. An integer overflow flaw, leading to a heap-based buffer overflow, was found in the way the glibc library read timezone files. If a carefully-crafted timezone file was loaded by an application linked against glibc, it could cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2009-5029) A flaw was found in the way the ldd utility identified dynamically linked libraries. If an attacker could trick a user into running ldd on a malicious binary, it could result in arbitrary code execution with the privileges of the user running ldd. (CVE-2009-5064) An integer overflow flaw, leading to a heap-based buffer overflow, was found in the way the glibc library loaded ELF (Executable and Linking Format) files. If a carefully-crafted ELF file was loaded by an application linked against glibc, it could cause the application to crash or, potentially, execute arbitrary code with the privileges of the user running the application. (CVE-2010-0830) It was found that the glibc addmntent() function, used by various mount helper utilities, did not handle certain errors correctly when updating the mtab (mounted file systems table) file. If such utilities had the setuid bit set, a local attacker could use this flaw to corrupt the mtab file. (CVE-2011-1089) A denial of service flaw was found in the remote procedure call (RPC) implementation in glibc. A remote attacker able to open a large number of connections to an RPC service that is using the RPC implementation from glibc, could use this flaw to make that service use an excessive amount of CPU time.
