A vulnerability, which was classified as critical, was found in xinetd up to 2.1.8.9pre11-1 (Multimedia Player Software). Affected is the function svc_logprint of the component Ident Response Handler. The manipulation with an unknown input leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Buffer overflow in Linux xinetd 2.1.8.9pre11-1 and earlier may allow remote attackers to execute arbitrary code via a long ident response, which is not properly handled by the svc_logprint function.

The bug was discovered 06/08/2001. The weakness was released 10/18/2001 by zen-parse (Website). The advisory is available at debian.org. This vulnerability is traded as CVE-2001-0763. 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.

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 was handled as a non-public zero-day exploit for at least 9 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 14900 (Debian DSA-063-1 : xinetd - change default umask), 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.

Upgrading to version 2.1.8.9pre15 eliminates this vulnerability. A possible mitigation has been published before and not just after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (6670), Exploit-DB (20908), Tenable (14900), SecurityFocus (BID 2840†) and OSVDB (5542†).
