Echo: openexr: security update to 3.1.13-2

high Tenable Cloud Security Plugin ID 462990

Description

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

 - OpenEXR is the reference implementation and specification for the EXR image format, widely used in the
 motion picture industry. In versions 3.4.0 through 3.4.11, the HTJ2K (High-Throughput JPEG 2000) decoder,
 ht_undo_impl() in OpenEXRCore is vulnerable to a heap-buffer-overflow READ. The ht_undo_imp function
 copies decoded pixels out of a per-line OpenJPH buffer using the EXR channel's declared width as the
 iteration count. The codestream embedded in the EXR chunk can declare different (smaller) tile/line
 dimensions than the EXR header advertises, but ht_undo_impl() does not validate this — it pulls width
 32-bit samples from cur_line->i32[] without checking the OpenJPH line buffer's actual length. A crafted
 EXR file produces a 4-byte heap-buffer-overflow READ immediately after a buffer allocated by
 ojph::local::codestream::finalize_alloc(). The bug is reachable through the standard scanline-decode entry
 point used by every consumer of exr_decoding_run/Imf::checkOpenEXRFile, including thumbnailers, asset
 pipelines, and the exrcheck utility — i.e. any application that opens untrusted EXR files. The result is a
 deterministic crash (DoS) and potential adjacent-heap leak. This issue has been fixed in version 3.4.12.
 (CVE-2026-45696)

Solution

Update the openexr library and its related packages to version 3.1.13-2 or later.
