"Various security problems have been fixed in the imlib2 image 
loaders :

  - A stack-based buffer overflow in loader_pnm.c could be
    used by attackers to execute code by supplying a
    handcrafted PNM image. (CVE-2006-4809)

  - A heap buffer overflow in loader_tga.c could potentially
    be used by attackers to execute code by supplying a
    handcrafted TGA image. (CVE-2006-4808)

  - A out of bounds memory read in loader_tga.c could be
    used to crash the imlib2 using application with a
    handcrafted TGA image. (CVE-2006-4807)

  - Various integer overflows in width*height calculations
    could lead to heap overflows which could potentially be
    used to execute code. Affected here are the ARGB, PNG,
    LBM, JPEG and TIFF loaders. (CVE-2006-4806)

Additionally loading of TIFF images on 64bit systems now works."

"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."
