Vulnerability details

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the png_image_read_composite() function when processing palette images with PNG_FLAG_OPTIMIZE_ALPHA enabled. A remote attacker can pass a specially crafted image file to the application, trigger an out-of-bounds read error and read contents of memory on the system.
