wmaker: buffer overflow in Window Maker image handling code

Package(s):wmaker windowmaker CVE #(s):CAN-2002-1277
Created:November 7, 2002 Updated:February 6, 2003
Description: Al Viro found a problem in the image handling code used in Window Maker, a popular NEXTSTEP like window manager. When creating an image it would allocate a buffer by multiplying the image width and height, but did not check for an overflow. This makes it possible to overflow the buffer. This could be exploited by using specially crafted image files (for example when previewing themes).
