Echo: openexr: security update to 3.1.13-2
medium Tenable Self-Hosted Container Security Plugin ID 462713
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- OpenEXR provides the specification and reference implementation of the EXR file format, an image storage
format for the motion picture industry. From 3.2.0 to before 3.2.7, 3.3.9, and 3.4.9, a signed integer
overflow exists in undo_pxr24_impl() in src/lib/OpenEXRCore/internal_pxr24.c at line 377. The expression
(uint64_t)(w * 3) computes w * 3 as a signed 32-bit integer before casting to uint64_t. When w is large,
this multiplication constitutes undefined behavior under the C standard. On tested builds (clang/gcc
without sanitizers), two's-complement wraparound commonly occurs, and for specific values of w the wrapped
result is a small positive integer, which may allow the subsequent bounds check to pass incorrectly. If
the check is bypassed, the decoding loop proceeds to write pixel data through dout, potentially extending
far beyond the allocated output buffer. This vulnerability is fixed in 3.2.7, 3.3.9, and 3.4.9.
(CVE-2026-34380)
