August 22, 2012

ImageMagick could be made to crash or run programs as your login if it opened a specially crafted file.

Summary

ImageMagick could be made to crash or run programs as your login if it

opened a specially crafted file.

Software Description:

- imagemagick: Image manipulation programs and library

Details:

Tom Lane discovered that ImageMagick would not always properly allocate

memory. If a user or automated system using ImageMagick were tricked into

opening a specially crafted PNG image, an attacker could exploit this to

cause a denial of service or possibly execute code with the privileges of

the user invoking the program.
