high Nessus Plugin ID 342109

Synopsis

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

Description

The remote openSUSE 16 host has a package installed that is affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:21687-1 advisory.

- CVE-2026-59881: excessive resource consumption due to WebSocket client accepting compressed frames without negotiated permessage-deflate (bsc#1273125).
- CVE-2026-69243: HTTP request smuggling via the WebSocket upgrade procedure (bsc#1273553).
- CVE-2026-69244: out-of-bounds heap read in the C response parser while building an error message for a malformed response (bsc#1273552).

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 python313-aiohttp package.
