Detailsinfo

A vulnerability, which was classified as critical, has been found in xtell 1.91.1/2.6.1. This issue affects an unknown code block. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to 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. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Buffer overflows in xtell (xtelld) 1.91.1 and earlier, and 2.x before 2.7, allows remote attackers to execute arbitrary code via (1) a long DNS hostname that is determined using reverse DNS lookups, (2) a long AUTH string, or (3) certain data in the xtell request.

The weakness was disclosed 06/25/2002 (Website). The advisory is shared at debian.org. The identification of this vulnerability is CVE-2002-0332. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. Technical details are unknown but a public exploit is available.

A public exploit has been developed in ANSI C. The exploit is available at securityfocus.com. It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 14958 (Debian DSA-121-1 : xtell - buffer overflow, symlink problem, '..' directory traversal), 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 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 (8312), Exploit-DB (21309), Tenable (14958) and SecurityFocus (BID 4193†). The entry VDB-18318 is pretty similar. If you want to get the best quality for vulnerability data then you always have to consider VulDB.
