GLSA 200411-28: X.Org, XFree86: libXpm vulnerabilities

http://security.gentoo.org/

Severity:	normal
Title:	X.Org, XFree86: libXpm vulnerabilities
Date:	11/19/2004
Bugs:	#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	Vulnerable	Unaffected	Architecture(s)
x11-base/xorg-x11	< 6.8.0-r3	>= 6.8.0-r3	All supported architectures
x11-base/xfree	< 4.3.0-r8	>= 4.3.0-r8	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:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=x11-base/xorg-x11-6.7.0-r3"

All XFree86 users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=x11-base/xfree-x11-4.3.0-r8"
