imagemagick - several

Several vulnerabilities have been discovered in ImageMagick, a
commonly used image manipulation library. These problems can be
exploited by a carefully crafted graphic image. The Common
Vulnerabilities and Exposures project identifies the following
problems:

• CAN-2005-0397
  Tavis Ormandy discovered a format string vulnerability in the
  filename handling code which allows a remote attacker to cause a
  denial of service and possibly execute arbitrary code.

• CAN-2005-0759
  Andrei Nigmatulin discovered a denial of service condition which
  can be caused by an invalid tag in a TIFF image.

• CAN-2005-0760
  Andrei Nigmatulin discovered that the TIFF decoder is vulnerable
  to accessing memory out of bounds which will result in a
  segmentation fault.

• CAN-2005-0762
  Andrei Nigmatulin discovered a buffer overflow in the SGI parser
  which allows a remote attacker to execute arbitrary code via a
  specially crafted SGI image file.

For the stable distribution (woody) these problems have been fixed in
version 5.4.4.5-1woody6.

For the unstable distribution (sid) these problems have been fixed in
version 6.0.6.2-2.2.

We recommend that you upgrade your imagemagick package.
