GLSA 200806-03: Imlib 2: User-assisted execution of arbitrary code

Severity:	normal
Title:	Imlib 2: User-assisted execution of arbitrary code
Date:	06/08/2008
Bugs:	#223965
ID:	200806-03

Synopsis

Two vulnerabilities in Imlib 2 may allow for the execution of arbitrary code.

Background

Imlib 2 is an advanced replacement library for libraries like libXpm.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
media-libs/imlib2	< 1.4.0-r1	>= 1.4.0-r1	All supported architectures

Description

Stefan Cornelius (Secunia Research) reported two boundary errors in Imlib2:

One of them within the load() function in the file src/modules/loaders/loader_pnm.c when processing the header of a PNM image file, possibly leading to a stack-based buffer overflow.
The second one within the load() function in the file src/modules/loader_xpm.c when processing an XPM image file, possibly leading to a stack-based buffer overflow.

Impact

A remote attacker could entice a user to open a specially crafted PNM or XPM image, possibly resulting in the execution of arbitrary code with the rights of the user running the application using Imlib 2.

Workaround

There is no known workaround at this time.

Resolution

All Imlib 2 users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=media-libs/imlib2-1.4.0-r1"
