|Gentoo Linux Security Advisory
Title: zoo: Stack-based buffer overflow (GLSA 200603-05)
Date: March 06, 2006
A stack-based buffer overflow in zoo may be exploited to execute arbitrary code through malicious ZOO archives.
zoo is a file archiving utility for maintaining collections of files, written by Rahul Dhesi.
Vulnerable: < 2.10-r1
Unaffected: >= 2.10-r1
Architectures: All supported architectures
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.
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.
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"
