The cupsUTF32ToUTF8() function in CUPS's cups/transcode.c lacks a source-length bound and can read past the end of the source buffer, resulting in a heap out-of-bounds read. This is reachable via SNMP supply-description parsing in backend/snmp-supplies.c with attacker-controlled content.

The remote openSUSE 16 host has packages installed that are affected by a vulnerability as referenced in the openSUSE- SU-2026:21893-1 advisory.

    This update for cups fixes the following issue:

    - CVE-2026-87875: heap out-of-bounds read in `cupsUTF32ToUTF8()` due to missing source-length bound can be     reached via       the SNMP supply-description parsing (bsc#1279945).

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

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