Red Hat reported:
Tavis Ormandy discovered several integer and buffer overflow flaws in the
way ImageMagick decodes XCF, SGI, and Sun bitmap graphic files. An attacker
could execute arbitrary code on a victim's machine if they were able to
trick the victim into opening a specially crafted image file.
[CVE-2006-3743, CVE-2006-3744]
[Editor's note: The SGI file bug may have been covered in a previous Alert.]
