Debian Security Advisory DSA-5348-1 [email protected]

Package : haproxy
CVE ID : CVE-2023-0056 CVE-2023-25725

Two vulnerabilities were discovered in HAProxy, a fast and reliable load
balancing reverse proxy, which may result in denial of service, or
bypass of access controls and routing rules via specially crafted
requests.

For the stable distribution (bullseye), these problems have been fixed in
version 2.2.9-2+deb11u4.

We recommend that you upgrade your haproxy packages.

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