In short

IrfanView has a flaw when opening PSP image files that allows attackers to run malicious code on your computer if you open a specially crafted file. The program doesn't properly check the file contents before processing it, leading to memory corruption.

Technical detail

Out-of-bounds write vulnerability in IrfanView's PSP file parser due to insufficient input validation. Attack vector requires user interaction (opening malicious PSP file); exploitation results in arbitrary code execution in the context of the IrfanView process. Memory safety violation allows attacker-controlled data to be written past allocated buffer boundaries.

Summary generated and translated by AI from the official description.
