Detailsinfo

A vulnerability, which was classified as problematic, was found in X.org X11 up to 7.x (Windowing System Software). This affects some unknown functionality of the file Xsession of the component xdm. The manipulation with an unknown input leads to a race condition vulnerability. CWE is classifying the issue as CWE-362. The product contains a code sequence that can run concurrently with other code, and the code sequence requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence that is operating concurrently. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Race condition in the Xsession script, as used by X Display Manager (xdm) in NetBSD before 20060212, X.Org before 20060225, and Solaris 8 through 10 before 20061006, causes a user s Xsession errors file to have weak permissions before a chmod is performed, which allows local users to read Xsession errors files of other users.

The bug was discovered 10/06/2006. The weakness was presented 10/17/2006 (Website). The advisory is shared at bugs.freedesktop.org. This vulnerability is uniquely identified as CVE-2006-5214 since 10/09/2006. The attack can only be initiated within the local network. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available.

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 4 days. During that time the estimated underground price was around $0-$5k. The vulnerability scanner Nessus provides a plugin with the ID 23447 (Solaris 8 (x86) : 111845-04), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Solaris Local Security Checks and running in the context l.

Applying a patch is able to eliminate this problem. The bugfix is ready for download at freedesktop.org. A possible mitigation has been published 4 months after the disclosure of the vulnerability.
