  "description": "HAProxy is a free, very fast and reliable solution offering high availability, load balancing, and proxying for TCP and HTTP-based applications. It is particularly suited for very high traffic web sites and powers quite a number of the world's most visited ones. \r\n\r\nSecurity Fix(es):\r\n\r\nInitial description: Router PODs frequently getting restarted and haproxy process is receiving the segfault but it is not generating coredump even though the core file size is unlimited.\r\n\r\nUpstream bug: https://github.com/haproxy/haproxy/issues/1972(CVE-2023-0056)\r\n\r\nHAProxy 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)",
