[GLSA-200603-05] zoo: Stack-based buffer overflow

Vulnerability Assessment Summary
zoo: Stack-based buffer overflow

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200603-05
(zoo: Stack-based buffer overflow)

Jean-Sebastien Guay-Leroux discovered a boundary error in the
fullpath() function in misc.c when processing overly long file and
directory names in ZOO archives.

Impact

A possible hacker could craft a malicious ZOO archive and entice someone
to open it using zoo. This would trigger a stack-based buffer overflow
and potentially permit execution of arbitrary code with the rights of
the victim user.

Workaround

There is no known workaround at this time.
