Description:
Imager could allow a remote attacker to cause a denial of service. This is caused by a segmentation fault that can occur when writing a 2 or 4 channel JPEG image or a 2 channel TGA image. A remote attacker could exploit this vulnerability to cause a Perl application that uses an affected version of the Imager module to crash.
