Medium Nessus Plugin ID 58618


The remote Ubuntu host is missing one or more security-related patches.


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.

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).

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.
