Synopsis
Two vulnerabilities in Imlib 2 may allow for the execution of arbitrary
code.
2.
Impact Information
Background
Imlib 2 is an advanced replacement library for libraries like libXpm.
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.
3.
Resolution Information
Workaround
There is no known workaround at this time.
Resolution
All Imlib 2 users should upgrade to the latest version:
Code Listing 3.1: Resolution |
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/imlib2-1.4.0-r1"
