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

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.
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.
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.
There is no known workaround at this time.
All imlib users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=media-libs/imlib-1.9.14-r3"
ImageMagick, imlib and imlib2 contain exploitable buffer overflow vulnerabilities in the BMP image processing code.
| Package | Arch | Vulnerable | Unaffected |
|---|---|---|---|
| media-gfx/imagemagick | * | < 6.0.7.1 | >= 6.0.7.1 |
| media-libs/imlib | * | < 1.9.14-r2 | >= 1.9.14-r2 |
| media-libs/imlib2 | * | < 1.1.2 | >= 1.1.2 |
ImageMagick is a suite of image manipulation utilities and libraries used for a wide variety of image formats. imlib is a general image loading and rendering library.
Due to improper bounds checking, ImageMagick and imlib are vulnerable to a buffer overflow when decoding runlength-encoded bitmaps. This bug can be exploited using a specially-crafted BMP image and could potentially allow remote code execution when this image is decoded by the user.
A specially-crafted runlength-encoded BMP could lead ImageMagick and imlib to crash or potentially execute arbitrary code.
There is no known workaround at this time.
All ImageMagick users should upgrade to the latest version:
# emerge sync # emerge -pv ">=media-gfx/imagemagick-6.0.7.1" # emerge ">=media-gfx/imagemagick-6.0.7.1"
All imlib users should upgrade to the latest version:
# emerge sync # emerge -pv ">=media-libs/imlib-1.9.14-r2" # emerge ">=media-libs/imlib-1.9.14-r2"
All imlib2 users should upgrade to the latest version:
# emerge sync # emerge -pv ">=media-libs/imlib2-1.1.2" # emerge ">=media-libs/imlib2-1.1.2"
