Description

Damian Put discovered a buffer overflow in imagemagick's SGI file format decoder. By tricking an user or automated system into processing a specially crafted SGI image, this could be exploited to execute arbitrary code with the user's privileges.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
