GNU C Library up to 2.12.2 proftpd.gnu.c resource management

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.

Detailsinfo

A vulnerability was found in GNU C Library (Software Library). It has been rated as problematic. Affected by this issue is an unknown function of the file proftpd.gnu.c. The manipulation with an unknown input leads to a resource management vulnerability. Using CWE to declare the problem leads to CWE-399. Impacted is availability. CVE summarizes:

Stack consumption vulnerability in the regcomp implementation in the GNU C Library (aka glibc or libc6) through 2.11.3, and 2.12.x through 2.12.2, allows context-dependent attackers to cause a denial of service (resource exhaustion) via a regular expression containing adjacent repetition operators, as demonstrated by a {10,}{10,}{10,}{10,} sequence in the proftpd.gnu.c exploit for ProFTPD.

The weakness was disclosed 01/13/2011 by Maksymilian Arciemowicz as confirmed advisory (CERT.org). The advisory is available at kb.cert.org. This vulnerability is handled as CVE-2010-4052. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. Technical details as well as a public exploit are known.

A public exploit has been developed by Maksymilian Arciemowicz in ANSI C and been published before and not just after the advisory. The exploit is available at securityfocus.com. It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 6 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 53460 (Fedora 15 : proftpd-1.3.4-0.8.rc2.fc15 (2011-5098)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Fedora Local Security Checks.

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 (63944), Exploit-DB (15935), Tenable (53460), SecurityFocus (BID 45233†) and SecurityTracker (ID 1024832†). The entry VDB-56041 is pretty similar. If you want to get best quality of vulnerability data, you may have to visit VulDB.
