Slackware Linux 15.0 / current nghttp2 Vulnerability (SSA:2024-095-02)
medium Nessus Plugin ID 192934
Language:
Synopsis
The remote Slackware Linux host is missing a security update to nghttp2.Description
The version of nghttp2 installed on the remote host is prior to 1.61.0. It is, therefore, affected by a vulnerability as referenced in the SSA:2024-095-02 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
Upgrade the affected nghttp2 package.See Also
