Several vulnerabilities were discovered in imlib2, an image manipulation library.

  - CVE-2014-9762     A segmentation fault could occur when opening GIFs     without a colormap.

  - CVE-2014-9763     Several divisions by zero, resulting in a program crash,     could occur when handling PNM files.

  - CVE-2014-9764     A segmentation fault could occur when opening GIFs with     feh.

Jakub Wilk discovered an out of bounds read in the GIF loader implementation in Imlib2. An attacker could use this to cause a denial of service (application crash) or possibly obtain sensitive information. (CVE-2016-3994)

Yuriy M. Kaminskiy discovered an off-by-one error when handling coordinates in Imlib2. An attacker could use this to cause a denial of service (application crash). (CVE-2016-3993)

Yuriy M. Kaminskiy discovered that integer overflows existed in Imlib2 when handling images with large dimensions. An attacker could use this to cause a denial of service (memory exhaustion or application crash).
(CVE-2014-9771, CVE-2016-4024)

Kevin Ryde discovered that the ellipse drawing code in Imlib2 would attempt to divide by zero when drawing a 2x1 ellipse. An attacker could use this to cause a denial of service (application crash).
(CVE-2011-5326)

It was discovered that Imlib2 did not properly handled GIF images without colormaps. An attacker could use this to cause a denial of service (application crash). This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2014-9762)

It was discovered that Imlib2 did not properly handle some PNM images, leading to a division by zero. An attacker could use this to cause a denial of service (application crash). This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2014-9763)

It was discovered that Imlib2 did not properly handle error conditions when loading some GIF images. An attacker could use this to cause a denial of service (application crash). This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2014-9764).
