Gentoo Linux Security Advisory
Title: zoo: Stack-based buffer overflow (GLSA 200603-05)
Severity: normal
Exploitable: remote
Date: March 06, 2006
Bug(s): #123782
ID: 200603-05
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: app-arch/zoo
Vulnerable: < 2.10-r1
Unaffected: >= 2.10-r1
Architectures: All supported architectures
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: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=app-arch/zoo-2.10-r1" |
