NVD-CWE-OtherPublished: March 21, 2006· Updated: Jun 16, 2026
Official Description
X.Org server (xorg-server) 1.0.0 and later, X11R6.9.0, and X11R7.0 inadvertently treats the address of the geteuid function as if it is the return value of a call to geteuid, which allows local users to bypass intended restrictions and (1) execute arbitrary code via the -modulepath command line option or (2) overwrite arbitrary files via -logfile.
Technical Analysis
CVE-2006-0745 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A proof-of-concept (PoC) exploit exists for CVE-2006-0745. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
