Gentoo Linux Security Advisory

Title: giflib: Multiple vulnerabilities (GLSA 200511-03)
Severity: normal
Exploitable: remote
Date: November 04, 2005
Bug(s): #109997
ID: 200511-03

Synopsis

giflib may dereference NULL or write out of bounds when processing malformed images, potentially resulting in Denial of Service or arbitrary code execution.

Background

giflib is a library for reading and writing GIF images.

Affected Packages

Package: media-libs/giflib
Vulnerable: < 4.1.4
Unaffected: >= 4.1.4
Architectures: All supported architectures


Description

Chris Evans and Daniel Eisenbud independently discovered two out-of-bounds memory write operations and a NULL pointer dereference in giflib.

Impact

An attacker could craft a malicious GIF image and entice users to load it using an application making use of the giflib library, resulting in an application crash or potentially the execution of arbitrary code.

Workaround

There is no known workaround at this time.

Resolution

All giflib users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/giflib-4.1.4"


References

CVE-2005-2974
CVE-2005-3350
