Gentoo Linux Security Advisory

Title: imlib: Buffer overflows in image decoding (GLSA 200412-03)
Severity: normal
Exploitable: remote
Date: December 06, 2004
Bug(s): #72681
ID: 200412-03

Synopsis


Multiple overflows have been found in the imlib library image decoding
routines, potentially allowing execution of arbitrary code.


Background


imlib is an advanced replacement library for image manipulation
libraries like libXpm. It is called by numerous programs, including
gkrellm and several window managers, to help in displaying images.


Affected Packages

Package: media-libs/imlib
Vulnerable: <= 1.9.14-r2
Unaffected: >= 1.9.14-r3
Architectures: All supported architectures


Description


Pavel Kankovsky discovered that several overflows found in the
libXpm library (see GLSA 200409-34) also applied to imlib. He also
fixed a number of other potential flaws.


Impact


A remote attacker could entice a user to view a carefully-crafted
image file, which would potentially lead to execution of arbitrary code
with the rights of the user viewing the image. This affects any program
that makes use of the imlib library.


Workaround


There is no known workaround at this time.


Resolution


All imlib users should upgrade to the latest version:
Code:
# emerge --sync
    # emerge --ask --oneshot --verbose ">=media-libs/imlib-1.9.14-r3"
