VERIFY ADVISORY:
http://secunia.com/advisories/18586/

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

SOFTWARE:
LibAST 0.x
http://secunia.com/product/6963/

DESCRIPTION:
Johnny Mast has reported a vulnerability in LibAST, which potentially
can be exploited by malicious, local users to gain escalated
privileges.

The vulnerability is caused due to a boundary error in the
"conf_find_file()" function in conf.c. This can be exploited to cause
a stack-based buffer overflow and allows arbitrary code execution via
an overly long filename.

Successful exploitation requires that the library is linked with a
setuid or setgid application.

The vulnerability has been reported in versions prior to 0.7.

SOLUTION:
Update to version 0.7.
