Synopsis
========
A stack-based buffer overflow in zoo may be exploited to execute
arbitrary code through malicious ZOO archives.
Background
==========
zoo is a file archiving utility for maintaining collections of files,
written by Rahul Dhesi.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-arch/zoo < 2.10-r1 >= 2.10-r1
Description
===========
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
======
An attacker could craft a malicious ZOO archive and entice someone to
open it using zoo. This would trigger a stack-based buffer overflow and
potentially allow execution of arbitrary code with the rights of the
victim user.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All zoo users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-arch/zoo-2.10-r1"
