  • httpd: mod_dav: out-of-bounds read/write of zero byte (CVE-2006-20001)
  • httpd: mod_proxy_ajp: Possible request smuggling (CVE-2022-36760)
  • httpd: mod_proxy: HTTP response splitting (CVE-2022-37436)

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.

Bug Fix(es):

  • httpd-init fails to create localhost.crt, localhost.key due to “sscg” default now creates a /dhparams.pem and is not idempotent if the file /dhparams.pem already exists. (BZ#2165975)
