The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to an off-by-one error when parsing Postscript objects within the scan_ps() function in cups/raster-interpret.c. A remote attacker can trigger pass a specially crafted PPD file to the affected application, trigger a heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
