The Red Hat Enterprise Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine 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. It was discovered that the fix for the CVE-2013-1619 issue released via RHSA-2013:0636 introduced a regression in the way GnuTLS decrypted TLS/SSL encrypted records when CBC-mode cipher suites were used. A remote attacker could possibly use this flaw to crash a server or client application that uses GnuTLS.

20fa1ae17a3faa746d6808e1c768335a12673ba1fd3c272301749bf74dff189dMandriva Linux Security Advisory 2013-171 - A flaw was found in the way GnuTLS decrypted TLS record packets when using CBC encryption. The number of pad bytes read form the packet was not checked against the cipher text size, resulting in an out of bounds read. This could cause a TLS client or server using GnuTLS to crash. The updated packages have been patched to correct this issue.

It was discovered that the fix for the CVE-2013-1619 issue released via RHSA-2013:0588 introduced a regression in the way GnuTLS decrypted TLS/SSL encrypted records when CBC-mode cipher suites were used. A remote attacker could possibly use this flaw to crash a server or client application that uses GnuTLS. Users of GnuTLS are advised to upgrade to these updated packages, which correct this issue. For the update to take effect, all applications linked to the GnuTLS library must be restarted.
