[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.


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.


There is no known workaround at this time.


All zoo users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-arch/zoo-2.10-r1"

Network Security Threat Level: Medium
