- Ubuntu 16.04 LTS - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS
Summary:
Several security issues were fixed in Imlib2.
Software Description: - imlib2: Image manipulation and rendering library
Details:
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)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 16.04 LTS: libimlib2 1.4.7-1ubuntu0.1
Ubuntu 14.04 LTS: libimlib2 1.4.6-2ubuntu0.1
Ubuntu 12.04 LTS: libimlib2 1.4.4-1ubuntu0.1
