CVE-2012-1573

Name of the Vulnerable Software and Affected Versions GnuTLS versions prior to 3.0.15 GnuTLS versions prior to 2.12.18

Description The issue affects the gnutls package in Gentoo Linux, potentially compromising the confidentiality, integrity, and availability of protected information. Exploitation can occur remotely. Specifically, gnutls cipher.c in libgnutls does not properly handle data encrypted with a block cipher, allowing remote attackers to cause a denial of service via a crafted record, such as a crafted GenericBlockCipher structure.

Recommendations For versions prior to 2.12.18, update to version 2.12.18 or later. For versions prior to 3.0.15, update to version 3.0.15 or later. As a temporary workaround, consider restricting access to the gnutls cipher.c function in libgnutls until a patch is available.
