Amazon Linux 2023 Security Advisory: ALAS-2024-592
Advisory Release Date: 2024-04-25 16:39 Pacific
Advisory Updated Date: 2024-04-25 16:39 Pacific
Severity:
Important
Issue Overview:
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)
Affected Packages:
nghttp2
Issue Correction:
