SUSE SLES12 Security Update : nghttp2 (SUSE-SU-2024:1156-1)

medium Nessus Plugin ID 193064

Language:

Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2024:1156-1 advisory.

- nghttp2 is an implementation of the Hypertext Transfer Protocol version 2 in C. The nghttp2 library prior to version 1.61.0 keeps reading the unbounded number of HTTP/2 CONTINUATION frames even after a stream is reset to keep HPACK context in sync. This causes excessive CPU usage to decode HPACK stream. nghttp2 v1.61.0 mitigates this vulnerability by limiting the number of CONTINUATION frames it accepts per stream.
There is no workaround for this vulnerability. (CVE-2024-28182)

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

Solution

Update the affected libnghttp2-14, libnghttp2-14-32bit and / or libnghttp2-devel packages.
