CVE-2023-44487

TITLE

Ubuntu Security Notice USN-6505-1

DESCRIPTION

The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023. This advisory contains the RPM packages for Red Hat OpenShift Container Platform 4.13.23. All OpenShift Container Platform 4.13 users are advised to upgrade to these updated packages and images when they are available in the appropriate release channel. To check for available updates, use the OpenShift CLI (oc) or web console. Description: Varnish Cache is a high-performance HTTP accelerator. It stores web pages in memory so web servers don't have to create the same web page over and over again, giving the website a significant speed up. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 - ------------------------------------------------------------------------- Debian Security Advisory DSA-5570-1 security@debian.org https://www.debian.org/security/ Moritz Muehlenhoff December 01, 2023 https://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : nghttp2 CVE ID : CVE-2023-44487 It was discovered that libnghttp2, a library implementing the HTTP/2 protocol, handled request cancellation incorrectly.
