Description

This security bulletin contains information about 1 security vulnerability.


1) Cryptographic issues (CVE-ID: CVE-2012-1573)

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

gnutls_cipher.c in libgnutls in GnuTLS before 2.12.17 and 3.x before 3.0.15 does not properly handle data encrypted with a block cipher, which allows remote attackers to cause a denial of service (heap memory corruption and application crash) via a crafted record, as demonstrated by a crafted GenericBlockCipher structure.


Remediation

Install update from vendor's website.
