Debian Security Advisory DSA-4649-1 [email protected]
https://www.debian.org/security/ Sebastien Delafond
April 02, 2020 https://www.debian.org/security/faq
Package : haproxy
CVE ID : CVE-2020-11100
Felix Wilhelm of Google Project Zero discovered that HAProxy, a TCP/HTTP
reverse proxy, did not properly handle HTTP/2 headers. This would allow
an attacker to write arbitrary bytes around a certain location on the
heap, resulting in denial-of-service or potential arbitrary code
execution.
For the stable distribution (buster), this problem has been fixed in
version 1.8.19-1+deb10u2.
We recommend that you upgrade your haproxy packages.
For the detailed security status of haproxy please refer to
its security tracker page at:
https://security-tracker.debian.org/tracker/haproxy
