CVE-2023-44442

GIMP PSD File Parsing Heap-based Buffer Overflow Remote Code Execution
Vulnerability. This vulnerability allows remote attackers to execute
arbitrary code on affected installations of GIMP. 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 PSD 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
arbitrary code in the context of the current process. Was ZDI-CAN-22094.
