MGASA-2016-0140 - Updated imlib2 packages fix security vulnerabilities

Publication date: 13 Apr 2016
URL: http://advisories.mageia.org/MGASA-2016-0140.html
Type: security
Affected Mageia releases: 5
CVE: CVE-2016-3993,
     CVE-2016-3994,
     CVE-2011-5326

Description:
Updated imlib2 packages fix security vulnerabilities:

An out-of-bounds read caused by an off-by-one error in __imlib_MergeUpdate()
in src/lib/updates.c in imlib2 1.4.8 and earlier (CVE-2016-3993).

An out-of-bounds read from colormap in the GIF loader in imlib2 1.4.8 and
earlier can result in denial of service and potential host memory exposure
(CVE-2016-3994).

Attempting to draw a 2x1 ellipse with e.g. imlib_image_draw_ellipse(x, y, 2, 1)
causes a divide-by-zero in imlib2 1.4.8 and earlier, resulting in a denial of
service if an application uses the draw command with untrusted input
(CVE-2011-5326).
