AZL-27912 CVE-2023-40225 affecting package haproxy for versions less than 2.4.24-1

HAProxy through 2.0.32, 2.1.x and 2.2.x through 2.2.30, 2.3.x and 2.4.x through 2.4.23, 2.5.x and 2.6.x before 2.6.15, 2.7.x before 2.7.10, and 2.8.x before 2.8.2 forwards empty Content-Length headers, violating RFC 9110 section 8.6.

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.
