high Nessus Plugin ID 350158

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-2026:21901-1 advisory.

- CVE-2026-85197: heap use-after-free in HTTP/2 `client on_data_read()` via `GOAWAY` during body upload (bsc#1279238).
- CVE-2026-85534: heap buffer overflow in `SoupSession` through `on_data_source_read_callback()` via `SETTINGS` frame with crafted `INITIAL_WINDOW_SIZE` (bsc#1279239).

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

Update the affected libsoup-3_0-0, libsoup-devel, libsoup-lang and / or typelib-1_0-Soup-3_0 packages.
