========================================================================== Ubuntu Security Notice USN-1418-1 April 05, 2012
gnutls13, gnutls26 vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 11.10 - Ubuntu 11.04 - Ubuntu 10.10 - Ubuntu 10.04 LTS - Ubuntu 8.04 LTS
Summary:
The GnuTLS library could be made to crash under certain conditions.
Software Description: - gnutls26: the GNU TLS library - commandline utilities - gnutls13: the GNU TLS library - commandline utilities
Details:
Alban Crequy discovered that the GnuTLS library incorrectly checked array bounds when copying TLS session data. A remote attacker could crash a client application, leading to a denial of service, as the client application prepared for TLS session resumption. (CVE-2011-4128)
Matthew Hall discovered that the GnuTLS library incorrectly handled TLS records. A remote attacker could crash client and server applications, leading to a denial of service, by sending a crafted TLS record. (CVE-2012-1573)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 11.10: libgnutls26 2.10.5-1ubuntu3.1
Ubuntu 11.04: libgnutls26 2.8.6-1ubuntu2.1
Ubuntu 10.10: libgnutls26 2.8.6-1ubuntu0.1
Ubuntu 10.04 LTS: libgnutls26 2.8.5-2ubuntu0.1
Ubuntu 8.04 LTS: libgnutls13 2.0.4-1ubuntu2.7
In general, a standard system update will make all the necessary changes.
