imlib2 contains several vulnerabilities that could lead to the remote execution of arbitrary code or a Denial of Service.
|Package||media-libs/imlib2 on all architectures|
|Affected versions||< 1.3.0|
|Unaffected versions||>= 1.3.0|
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.
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.
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.
There is no known workaround at this time.
All imlib2 users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/imlib2-1.3.0"
