Description OSIDB Bzimport 2025-06-24 13:49:50 UTC 
In some mod_ssl configurations on Apache HTTP Server versions through to 2.4.63, an HTTP desynchronisation attack allows a man-in-the-middle attacker to hijack an HTTP session via a TLS upgrade. Only configurations using \"SSLEngine optional\" to enable TLS upgrades are affected. Upstream recommends users to upgrade to version 2.4.64,
which removes support for TLS upgrade.
