Description Vladimir Vasilev 2026-10-02 11:16:47 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

A memory calculation bug in mod_dav in Apache httpd 2.4.67 and earlier allows an attacker with permission to create WebDAV locks to crash server child processes.

Users are recommended to upgrade to version 2.4.69, which fixes this issue
