Description

An exploitable integer overflow vulnerability exists in the JPEG 2000 image parsing functionality of freedesktop.org Poppler 0.53.0. A specially crafted PDF file can lead to an integer overflow causing out of bounds memory overwrite on the heap resulting in potential arbitrary code execution. To trigger this vulnerability, a victim must open the malicious PDF in an application using this library.

• CWE-190Integer Overflow or WraparoundThe product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
