CVE-2024-5876
IrfanView PSP File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability
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.
