Secunia

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.
