Description

PCSX2 is a free and open-source PlayStation 2 (PS2) emulator. A stack-based buffer overflow exists in the Kprintf_HLE function of PCSX2 versions up to 2.3.414. Opening a disc image that logs a specially crafted message may allow a remote attacker to execute arbitrary code if the user enabled IOP Console Logging. This vulnerability is fixed in 2.3.414.
