Package name imlib2
Date August 10th, 2007
Advisory ID MDKSA-2007:156
Affected versions 2007.1
Synopsis Updated imlib2 packages fix several issues

Problem Description

M Joonas Pihlaja discovered several vulnerabilities in the Imlib2
graphics library.

The load() function of several of the Imlib2 image loaders does not
check the width and height of an image before allocating memory. As
a result, a carefully crafted image file can trigger a segfault when
an application using Imlib2 attempts to view the image. (CVE-2006-4806)

The tga loader fails to bounds check input data to make sure the
input data doesn load outside the memory mapped region. (CVE-2006-4807)

The RLE decoding loops of the load() function in the tga loader does
not check that the count byte of an RLE packet doesn cause a heap
overflow of the pixel buffer. (CVE-2006-4808)

The load() function of the pnm loader writes arbitrary length user
data into a fixed size stack allocated buffer buf[] without bounds
checking. (CVE-2006-4809)

Updated packages have been patched to prevent these issues.
