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.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - 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

  - OpenEXR provides the specification and reference implementation of the EXR file format, an image storage     format for the motion picture industry. In versions 3.3.0 through 3.3.5 and 3.4.0 through 3.4.2, while     fuzzing `openexr_exrcheck_fuzzer`, Valgrind reports a conditional branch depending on uninitialized data     inside `generic_unpack`. This indicates a use of uninitialized memory. The issue can result in undefined     behavior and/or a potential crash/denial of service. Versions 3.3.6 and 3.4.3 fix the issue.
    (CVE-2025-64181)
