CVE-2013-3486Network attack vector

Code execution via FPX property-set integer overflow

Published Jan 27, 2020 · Updated Aug 6, 2024

Integer overflow in IrfanView Software IrfanView FPX PlugIn 4.3 allows remote attackers to execute code via a crafted FlashPix file. Fpx.dll performs overflow-prone integer arithmetic while processing Summary Information Property Set sections, causing a heap-based buffer overflow. A user must open the crafted image in 32-bit IrfanView; successful exploitation runs attacker-controlled code in the user's process context.
