Discussion

CUPS 'cupsFileOpen' function Symlink Attack Local Privilege Escalation Vulnerability

CUPS (Common UNIX Printing System) is prone to a local privilege-escalation vulnerability.

An attacker with local access could potentially exploit this issue to perform symbolic-link attacks, overwriting arbitrary files in the context of the affected application.

Successfully mounting a symlink attack may allow the attacker to delete or corrupt sensitive files, which may result in a denial of service. Other attacks may also be possible.

Versions prior to CUPS 1.4.4 are vulnerable.
