Buffer overflow in Sun JDK and Java Runtime Environment (JRE) 5.0 Update 9 and earlier, SDK and JRE 1.4.2_12 and earlier, and SDK and JRE 1.3.1_18 and earlier allows applets to gain privileges via a GIF image with a block with a 0 width field, which triggers memory corruption.

According to its version number, the Sun JRE running on the remote host has a buffer overflow issue that can be triggered when parsing a GIF image with the image width in an image block set to 0.  If an attacker can trick a user on the affected system into processing a specially crafted image file, say by visiting a malicious website, the attacker may be able to leverage this flaw to execute arbitrary code on the affected system subject to the user's privileges.
