ID CVE-2008-1950
Summary Integer signedness error in the _gnutls_ciphertext2compressed function in lib/gnutls_cipher.c in libgnutls in GnuTLS before 2.2.4 allows remote attackers to cause a denial of service (buffer over-read and crash) via a certain integer value in the Random field in an encrypted Client Hello message within a TLS record with an invalid Record Length, which leads to an invalid cipher padding length, aka GNUTLS-SA-2008-1-3.

This update has been rated as having important security impact by the Red Hat Security Response Team. The GnuTLS Library provides support for cryptographic algorithms and protocols such as TLS. GnuTLS includes libtasn1, a library developed for ASN.1 structures management that includes DER encoding and decoding. Flaws were found in the way GnuTLS handles malicious client connections. A malicious remote client could send a specially crafted request to a service using GnuTLS that could cause the service to crash. (CVE-2008-1948, CVE-2008-1949, CVE-2008-1950) We believe it is possible to leverage the flaw CVE-2008-1948 to execute arbitrary code but have been unable to prove this at the time of releasing this advisory. Red Hat Enterprise Linux 4 does not ship with any applications directly affected by this flaw. Third-party software which runs on Red Hat Enterprise Linux 4 could, however, be affected by this vulnerability. Consequently, we have assigned it important severity. Users of GnuTLS are advised to upgrade to these updated packages, which contain a backported patch that corrects these issues.

    description Updated gnutls packages that fix several security issues are now available for Red Hat Enterprise Linux 5. This update has been rated as having critical security impact by the Red Hat Security Response Team. The GnuTLS Library provides support for cryptographic algorithms and protocols such as TLS. GnuTLS includes libtasn1, a library developed for ASN.1 structures management that includes DER encoding and decoding. Flaws were found in the way GnuTLS handles malicious client connections. A malicious remote client could send a specially crafted request to a service using GnuTLS that could cause the service to crash. (CVE-2008-1948, CVE-2008-1949, CVE-2008-1950) We believe it is possible to leverage the flaw CVE-2008-1948 to execute arbitrary code but have been unable to prove this at the time of releasing this advisory. Red Hat Enterprise Linux 5 includes applications, such as CUPS, that would be directly vulnerable to any such an exploit, however. Consequently, we have assigned it critical severity. Users of GnuTLS are advised to upgrade to these updated packages, which contain a backported patch that corrects these issues.

  • NASL family Debian Local Security Checks
    NASL id DEBIAN_DSA-1581.NASL
    description Several remote vulnerabilities have been discovered in GNUTLS, an implementation of the SSL/TLS protocol suite. NOTE: The libgnutls13 package, which provides the GNUTLS library, does not contain logic to automatically restart potentially affected services. You must restart affected services manually (mainly Exim, using '/etc/init.d/exim4 restart') after applying the update, to make the changes fully effective. Alternatively, you can reboot the system. The Common Vulnerabilities and Exposures project identifies the following problems : - CVE-2008-1948 A pre-authentication heap overflow involving oversized session resumption data may lead to arbitrary code execution. - CVE-2008-1949 Repeated client hellos may result in a pre-authentication denial of service condition due to a NULL pointer dereference. - CVE-2008-1950 Decoding cipher padding with an invalid record length may cause GNUTLS to read memory beyond the end of the received record, leading to a pre-authentication denial of service condition.

    description Multiple flaws were discovered in the connection handling of GnuTLS. A remote attacker could exploit this to crash applications linked against GnuTLS, or possibly execute arbitrary code with permissions of the application's user. Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

    description The remote host is affected by the vulnerability described in GLSA-200805-20 (GnuTLS: Execution of arbitrary code) Ossi Herrala and Jukka Taimisto of Codenomicon reported three vulnerabilities in libgnutls of GnuTLS: 'Client Hello' messages containing an invalid server name can lead to a buffer overflow when evaluating 'Security Parameters' (CVE-2008-1948). Multiple 'Client Hello' messages can lead to a NULL pointer dereference (CVE-2008-1949). A TLS handshake including an encrypted 'Client Hello' message and an invalid record length could lead to a buffer overread (CVE-2008-1950). Impact : Unauthenticated remote attackers could exploit these vulnerabilities to cause Denial of Service conditions in daemons using GnuTLS. The first vulnerability (CVE-2008-1948) might allow for the execution of arbitrary code with the privileges of the daemon handling incoming TLS connections. Workaround : There is no known workaround at this time.

    description Flaws were found in the way GnuTLS handles malicious client connections. A malicious remote client could send a specially crafted request to a service using GnuTLS that could cause the service to crash. (CVE-2008-1948, CVE-2008-1949, CVE-2008-1950) At this time we have not seen any code that is using this exploit. But in Scientific Linux 5 there are some applications, that would be directly vulnerable if/when there is an exploit. Because of the potential threat we are labeling this important.
