Description

Technical Description

A local overflow exists in Xsok. The program fails to bounds check the "-xsokdir" command line argument resulting in a buffer overflow. With a specially crafted request, an attacker can cause privilege escalation to the games GID resulting in a loss of confidentiality, integrity, and/or availability.

Solution Description

Currently, there are no known upgrades or patches to correct this issue. It is possible to correct the flaw by implementing the following workaround(s): Remove suid or sgid bits for the program.
