A vulnerability, which was classified as very critical, was found in Pidgin (Messaging Software). Affected is the function msn_slplink_process_msg. The manipulation with an unknown input leads to a resource management vulnerability. CWE is classifying the issue as CWE-399. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

The msn_slplink_process_msg function in libpurple/protocols/msn/slplink.c in libpurple, as used in Pidgin (formerly Gaim) before 2.5.9 and Adium 1.3.5 and earlier, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) by sending multiple crafted SLP (aka MSNSLP) messages to trigger an overwrite of an arbitrary memory location. NOTE: this issue reportedly exists because of an incomplete fix for CVE-2009-1376.

The weakness was presented 05/02/2009 by CORE Security with CORE Security Technologies (Website). The advisory is shared for download at debian.org. This vulnerability is traded as CVE-2009-2694. 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 and a public exploit are known. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 08/20/2021).

A public exploit has been developed by Pierre Nogues in Java and been published 5 months after the advisory. 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 40966 (Mandriva Linux Security Advisory : pidgin (MDVSA-2009:230)), which helps to determine the existence of the flaw in a target environment.
