Scientific Linux Security Update : gnutls on SL6.x i386/x86_64 (20120327)

medium Nessus Plugin ID 61291

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

The GnuTLS library provides support for cryptographic algorithms and for protocols such as Transport Layer Security (TLS).

A flaw was found in the way GnuTLS decrypted malformed TLS records.
This could cause a TLS/SSL client or server to crash when processing a specially crafted TLS record from a remote TLS/SSL connection peer.
(CVE-2012-1573)

A boundary error was found in the gnutls_session_get_data() function.
A malicious TLS/SSL server could use this flaw to crash a TLS/SSL client or, possibly, execute arbitrary code as the client, if the client passed a fixed-sized buffer to gnutls_session_get_data() before checking the real size of the session data provided by the server.
(CVE-2011-4128)

Users of GnuTLS are advised to upgrade to these updated packages, which contain backported patches to correct these issues. For the update to take effect, all applications linked to the GnuTLS library must be restarted, or the system rebooted.

Solution

Update the affected packages.
