Execution of arbitrary code via local system, User access via local system

Exploit Included: Yes
|
Version(s): 1.02

Description:
Several buffer overflow vulnerabilities were reported in Xsok. A local user can gain elevated privileges on the target system.
In January 2004, 0x333 Outsiders Security Labs reported that a local user can supply a specially crafted '-xsokdir' command line parameter to trigger a buffer overflow in Xsok and execute arbitrary code. It is also reported that a local user can set a specially crafted LANG environment variable to trigger a buffer overflow.
Because Xsok is configured with set group id (setgid) games on some platforms, a local user may be able to gain elevated privileges on the target system.

A local user can execute arbitrary code with 'games' group privileges.
