Ethereal up to 0.10.12 memory allocation

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.

A vulnerability, which was classified as problematic, was found in Ethereal (Packet Analyzer Software). Affected is an unknown function. The manipulation with an unknown input leads to a memory allocation vulnerability. CWE is classifying the issue as CWE-789. The product allocates memory based on an untrusted, large size value, but it does not ensure that the size is within expected limits, allowing arbitrary amounts of memory to be allocated. This is going to have an impact on availability. CVE summarizes:

Multiple vulnerabilities in Ethereal 0.10.12 and earlier allow remote attackers to cause a denial of service (memory consumption) via unspecified vectors in the (1) ISAKMP, (2) FC-FCS, (3) RSVP, and (4) ISIS LSP dissector.

The bug was discovered 10/19/2005. The weakness was published 10/19/2005 by iDefense with iDEFENSE (Website). The advisory is available at ethereal.com. This vulnerability is traded as CVE-2005-3241 since 10/17/2005. The exploitability is told to be easy. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. Technical details are unknown but a public exploit is available.

A public exploit has been developed in ANSI C. The exploit is shared for download at securityfocus.com. It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 22713 (Debian DSA-1171-1 : ethereal - several vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 117829 (CentOS Security Update for Ethereal (CESA-2005:809)).
