Amazon Linux 2023 Security Advisory: ALAS2023-2026-1364
Advisory Released Date: 2026-01-23
Advisory Updated Date: 2026-01-23
Academy Software Foundation OpenEXR EXR File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Academy Software Foundation OpenEXR. 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 EXR 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-27946. (CVE-2025-12495)
