 ------------------------------------------------------------------------- Debian LTS Advisory DLA-3804-1 [email protected] https://www.debian.org/lts/security/ Guilhem Moulin April 30, 2024 https://wiki.debian.org/LTS
 -------------------------------------------------------------------------

 Package : nghttp2 Version : 1.36.0-2+deb10u3 CVE ID : CVE-2024-28182 Debian Bug : 1068415

 Bartek Nowotarskis discovered that nghttp2, a set of programs implementing the HTTP/2, keeps reading CONTINUATION frames even after a stream is reset to keep HPACK context in sync. This causes excessive CPU usage to decode HPACK stream, which could lead to Denial of Service.

 The issue is mitigated by limiting the number of CONTINUATION frames it can accept after a HEADERS frame. The limit is configurable and defaults to 8.

 For Debian 10 buster, this problem has been fixed in version 1.36.0-2+deb10u3.

 We recommend that you upgrade your nghttp2 packages.

 For the detailed security status of nghttp2 please refer to its security tracker page at:
