OpenEXR provides the specification and reference implementation of the EXR file format, an image storage format for the motion picture industry. From versions 3.0.0 to before 3.2.9, 3.3.0 to before 3.3.11, and 3.4.0 to before 3.4.11, IDManifest::init() reconstructs strings from a prefix-compressed representation. If the previous string is longer than 255 bytes, the next string is expected to begin with a 2-byte prefix length. The code reads stringList[i][0] and stringList[i][1] without checking that the current string has at least two bytes. This issue has been patched in versions 3.2.9, 3.3.11, and 3.4.11.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1713 advisory.

    OpenEXR provides the specification and reference implementation of the EXR file format, an image storage     format for the motion picture industry. From versions 3.0.0 to before 3.2.9, 3.3.0 to before 3.3.11, and     3.4.0 to before 3.4.11, there is an integer overflow in ImageChannel::resize that leads to heap OOB write     via OpenEXRUtil public API. This issue has been patched in versions 3.2.9, 3.3.11, and 3.4.11.

    OpenEXR provides the specification and reference implementation of the EXR file format, an image storage     format for the motion picture industry. From versions 3.0.0 to before 3.2.9, 3.3.0 to before 3.3.11, and     3.4.0 to before 3.4.11, readVariableLengthInteger() decodes a variable-length integer from untrusted EXR     input without bounding the shift count. After enough continuation bytes, the code executes a left shift by     70 on a 64-bit value, which is undefined behavior. This issue has been patched in versions 3.2.9, 3.3.11,     and 3.4.11.--- From NIST (CVE-2026-42217)
