Out-of-bounds write vulnerability in PSP file parser due to insufficient input validation; remote code execution achievable via malicious PSP file requiring user interaction; attacker gains code execution in the context of the IrfanView process.
Summary generated and translated by AI from the official description.
IrfanView PSP File Parsing Out-Of-Bounds Write 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 user-supplied data, which can result in a write past the end of an allocated buffer.
