Detailsinfo

A vulnerability was found in libmcrypt 2.5.0/2.5.1 R4/2.5.2/2.5.3. It has been classified as problematic. This affects some unknown processing of the component Request Handler. The manipulation with an unknown input leads to a memory leak vulnerability. CWE is classifying the issue as CWE-401. The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory. This is going to have an impact on availability. The summary by CVE is:

Memory leak in libmcrypt before 2.5.5 allows attackers to cause a denial of service (memory exhaustion) via a large number of requests to the application, which causes libmcrypt to dynamically load algorithms via libtool.

The weakness was presented 01/17/2003 (Website). It is possible to read the advisory at debian.org. This vulnerability is uniquely identified as CVE-2003-0032. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. The technical details are unknown and an exploit is not publicly available.

The vulnerability scanner Nessus provides a plugin with the ID 12562 (FreeBSD : Buffer overflows in libmcrypt (92)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family FreeBSD Local Security Checks.

Upgrading to version 2.5.5 eliminates this vulnerability.

The vulnerability is also documented in the databases at X-Force (10988), Tenable (12562), SecurityFocus (BID 6512†) and Vulnerability Center (SBV-24217†). See VDB-20102 for similar entry. Be aware that VulDB is the high quality source for vulnerability data.
