In short

IrfanView has a flaw in how it reads PSP image files that allows attackers to crash the program or run malicious code if you open a specially crafted file. This happens because the program doesn't properly check the size of data before copying it into memory.

Technical detail

A heap-based buffer overflow exists in IrfanView's PSP file parser due to insufficient validation of user-supplied data length before copying to a heap buffer. Remote code execution is possible when a user opens a malicious PSP file, with the attacker code executing in the context of the vulnerable process.

Summary generated and translated by AI from the official description.
IrfanView PSP File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of IrfanView. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of PSP files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-23973.
