CVE-2016-4024

Integer overflow in imlib2 before 1.4.9 on 32-bit platforms allows remote attackers to execute arbitrary code via large dimensions in an image, which triggers an out-of-bounds heap memory write operation.

USN-3075-1 — imlib2 vulnerabilities

Affected: Ubuntu:14.04:LTS: imlib2, Ubuntu:16.04:LTS: imlib2

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…
