Gnu GnuTLS up to 2.10.2 Padding cryptographic issue

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Summaryinfo

A vulnerability marked as problematic has been reported in Gnu GnuTLS up to 2.10.2. Impacted is an unknown function of the component Padding. Performing a manipulation results in cryptographic issue. This vulnerability is cataloged as CVE-2012-0390. There is no exploit available.

Detailsinfo

A vulnerability, which was classified as problematic, was found in Gnu GnuTLS up to 2.10.2 (Network Encryption Software). This affects an unknown code of the component Padding. The manipulation with an unknown input leads to a cryptographic issue vulnerability. CWE is classifying the issue as CWE-310. This is going to have an impact on confidentiality. The summary by CVE is:

The DTLS implementation in GnuTLS 3.0.10 and earlier executes certain error-handling code only if there is a specific relationship between a padding length and the ciphertext size, which makes it easier for remote attackers to recover partial plaintext via a timing side-channel attack, a related issue to CVE-2011-4108.

The weakness was shared 01/05/2012 (Website). The advisory is shared at isg.rhul.ac.uk. This vulnerability is uniquely identified as CVE-2012-0390 since 01/05/2012. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1600 for this issue.

The vulnerability scanner Nessus provides a plugin with the ID 74550 (openSUSE Security Update : gnutls (openSUSE-2012-121)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family SuSE Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 166830 (SUSE Enterprise Linux Security Update for gnutls (SUSE-SU-2014:0320-1)).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.

The vulnerability is also documented in the databases at X-Force (72201), Tenable (74550), SecurityFocus (BID 51322†), Secunia (SA57260†) and Vulnerability Center (SBV-35367†).
