Package        : zgv
Vulnerability  : integer overflows, unsanitised input

Several vulnerabilities have been discovered in zgv, an SVGAlib
graphics viewer for the i386 architecture.  The Common Vulnerabilities
and Exposures Project identifies the following problems:


    Luke Macken and "infamous41md" independently discoverd multiple
    integer overflows in zgv.  Remote exploitation of an integer
    overflow vulnerability could allow the execution of arbitrary


    Mikulas Patocka discovered that malicious multiple-image (e.g.
    animated) GIF images can cause a segmentation fault in zgv.

For the stable distribution (woody) these problems have been fixed in
version 5.5-3woody1.

For the unstable distribution (sid) these problems will be fixed soon.

We recommend that you upgrade your zgv package immediately.
