Slackware 15.0: 2024-095-03 Urgent: Nginx Memory Leak Vulnerability

slackware
Calendar Grey April 4, 2024
Dist Slackware Esm H88
Freshly released nghttp2 packages for Slackware 15.0 address a significant security vulnerability linked to high CPU consumption caused by HEADER frames.
New nghttp2 packages are available for Slackware 15.0 and -current to fix a security issue

Summary

Here are the details from the Slackware 15.0 ChangeLog: patches/packages/nghttp2-1.61.0-i586-1_slack15.0.txz: Upgraded. This update fixes security issues: nghttp2 library 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 can accept after a HEADERS frame. For more information, see: https://github.com/nghttp2/nghttp2/security/advisories/GHSA-x6x3-gv8h-m57q https://www.kb.cert.org/vuls/id/421644 https://www.cve.org/CVERecord?id=CVE-2024-28182 (* Security fix *)
