Zoo "parse()" File Name Handling Buffer Overflow

CRITICAL:
Less critical

IMPACT:
Privilege escalation

WHERE:
Local system

SOFTWARE:
zoo 2.x
http://secunia.com/product/8297/

DESCRIPTION:
Josh Bressers has reported a vulnerability in zoo, which potentially
can be exploited by malicious, local users to gain escalated
privileges.

The vulnerability is caused due to a boundary error within the
"parse()" function in parse.c when creating an archive from a file
with an overly long pathname. This can be exploited to cause a
stack-based buffer overflow and may allow arbitrary code execution.

Successful exploitation requires that the user is e.g. tricked into
adding a file that is located in directories with overly long names
into an archive.

The vulnerability has been reported in version 2.10. Other versions
may also be affected.

SOLUTION:
Do not add files located in non-trusted directories into an archive.
