An update for haproxy is now available for HCE 2.0 Security Advisory hws_security@huawei.com Huawei Cloud HCE2-SA-2023-0142 Final 1.0 1.0 2023-03-27T08:19:41:00Z current version 2023-03-27T08:19:41:00Z 2023-03-27T08:19:41:00Z HCE SA Engine 1.0.0 An update for haproxy is now available for HCE 2.0 HCE Security has rated this update as having a security impact of Critical.A Common Vunlnerability Scoring System(CVSS)base score, which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section. Security Fix(es): HAProxy before 2.7.3 may allow a bypass of access control because HTTP/1 headers are inadvertently lost in some situations, aka "request smuggling." The HTTP header parsers in HAProxy may accept empty header field names, which could be used to truncate the list of HTTP headers and thus make some headers disappear after being parsed and processed for HTTP/1.0 and HTTP/1.1. For HTTP/2 and HTTP/3, the impact is limited because the headers disappear before being parsed and processed, as if they had not been sent by the client. The fixed versions are 2.7.3, 2.6.9, 2.5.12, 2.4.22, 2.2.29, and 2.0.31. (CVE-2023-25725) An uncontrolled resource consumption vulnerability was discovered in HAProxy which could crash the service. This issue could allow an authenticated remote attacker to run a specially crafted malicious server in an OpenShift cluster. The biggest impact is to availability.
