Ubuntu Security Notice USN-1544-1
August 22, 2012
A security issue affects these releases of Ubuntu and its derivatives:
Summary:
ImageMagick could be made to crash or run programs as your login if it
opened a specially crafted file.
Software Description:
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.

The problem can be corrected by updating your system to the following
package versions:
