Summary
Red Hat Security Advisory: haproxy security update
Notes
Topic
An update for haproxy is now available for Red Hat Enterprise Linux 9.2 Extended Update Support.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
The haproxy packages provide a reliable, high-performance network load balancer for TCP and HTTP-based applications.
Security Fix(es):
* haproxy: Proxy forwards malformed empty Content-Length headers (CVE-2023-40225)
* haproxy: untrimmed URI fragments may lead to exposure of confidential data on static servers (CVE-2023-45539)
For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
