SOL15637: GnuTLS vulnerability CVE-2013-2116
Security AdvisorySecurity Advisory
Original Publication Date: 10/06/2014
Description
The _gnutls_ciphertext2compressed function in lib/gnutls_cipher.c in GnuTLS
2.12.23 allows remote attackers to cause a denial of service (buffer over-read
and crash) via a crafted padding length. NOTE: this might be due to an
incorrect fix for CVE-2013-0169. (CVE-2013-2116)
Impact
An attacker may be able to cause a denial-of-service (DoS) attack.
Status
F5 Product Development has assigned ID 413968 (BIG-IP), 480426 (BIG-IQ), and
480427 (Enterprise Manager) to this vulnerability, and has evaluated the
currently supported releases for potential vulnerability.
To determine if your release is known to be vulnerable, the components or
features that are affected by the vulnerability, and for information about
releases or hotfixes that address the vulnerability, refer to the following
table:

*F5 Product Development has determined that the affected BIG-IP, BIG-IQ, and
Enterprise Manager versions ship with vulnerable GnuTLS code. However, the
vulnerable code is not used by default on these BIG-IP, BIG-IQ, or Enterprise
Manager systems. These products are only vulnerable if a GnuTLS server was
manually configured.
Recommended Action
If the previous table lists a version in the Versions known to be not
vulnerable column, you can eliminate this vulnerability by upgrading to the
listed version. If the table does not list any version in the column, then no
upgrade candidate currently exists.
