Gentoo Linux Security Advisory

Title: X.Org, XFree86: libXpm vulnerabilities (GLSA 200411-28)
Severity: normal
Exploitable: remote
Date: November 19, 2004
Bug(s): #68544
ID: 200411-28

Synopsis

libXpm contains several vulnerabilities that could lead to a Denial of Service and arbitrary code execution.

Background

libXpm is a pixmap manipulation library for the X Window System, included in both X.Org and XFree86.

Affected Packages

Package: x11-base/xorg-x11
Vulnerable: < 6.8.0-r3
Unaffected: >= 6.8.0-r3
Unaffected: >= 6.7.0-r3 < 6.7.1
Architectures: All supported architectures

Package: x11-base/xfree
Vulnerable: < 4.3.0-r8
Unaffected: >= 4.3.0-r8
Architectures: All supported architectures


Description

Several issues were discovered in libXpm, including integer overflows, out-of-bounds memory accesses, insecure path traversal and an endless loop.

Impact

An attacker could craft a malicious pixmap file and entice a user to use it with an application linked against libXpm. This could lead to Denial of Service or arbitrary code execution.

Workaround

There is no known workaround at this time.

Resolution

All X.Org users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=x11-base/xorg-x11-6.7.0-r3"
All XFree86 users should upgrade to the latest version:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=x11-base/xfree-x11-4.3.0-r8"
