imagemagick vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 5.04
- Ubuntu 4.10
Details
Damian Put discovered a buffer overflow in the PNM image decoder.
Processing a specially crafted PNM file with a small "colors" value
resulted in a crash of the application that used the ImageMagick
library. (CAN-2005-1275)
Another Denial of Service vulnerability was found in the XWD decoder.
Specially crafted invalid color masks resulted in an infinite loop
which caused the application using the ImageMagick library to stop
working and use all available CPU resources.
