A vulnerability was discovered in GD Graphics Library (aka libgd), as used in PHP that does not zero colorMap arrays before use. A specially crafted GIF image could use the uninitialized tables to read bytes from the top of the stack.
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.
