Synopsis

The remote openSUSE host is missing one or more security updates.

Description

The remote openSUSE 16 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:21336-1 advisory.

This update for openexr fixes the following issues

- CVE-2026-54920: unchecked integer overflows in Image::resize() followed by an exception can lead to an invalid delete via uninitialized pointers (bsc#1269703).
- CVE-2026-55059: row setter utilizing dataWindow.min.x instead of min.y can lead to a heap out-of-bounds write (bsc#1269702).
- CVE-2026-55373: integer overflow in roundListSizeUp() wrapping a 32-bit unsigned value to zero can lead to an infinite loop (bsc#1269701).

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution
