Synopsis ========
imlib2 contains several vulnerabilities that could lead to the remote execution of arbitrary code or a Denial of Service.
Background ==========
imlib2 is an advanced replacement for image manipulation libraries such as libXpm. It is utilized by numerous programs, including gkrellm and several window managers, to display images.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-libs/imlib2 < 1.3.0 >= 1.3.0
Description ===========
M. Joonas Pihlaja discovered several buffer overflows in loader_argb.c, loader_png.c, loader_lbm.c, loader_jpeg.c, loader_tiff.c, loader_tga.c, loader_pnm.c and an out-of-bounds memory read access in loader_tga.c.
Impact ======
An attacker can entice a user to process a specially crafted JPG, ARGB, PNG, LBM, PNM, TIFF, or TGA image with an "imlib2*" binary or another application using the imlib2 libraries. Successful exploitation of the buffer overflows causes the execution of arbitrary code with the permissions of the user running the application.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All imlib2 users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/imlib2-1.3.0"
