This vulnerability affects the way Apache handles encrypted session data.
If using a managed distribution like Ubuntu, ensure you have applied all security updates provided by the vendor. apache httpd 2.4.18 vulnerability
If upgrading is impossible, disabling the mod_http2 module mitigates the most critical risks associated with this specific version. This vulnerability affects the way Apache handles encrypted
In Apache versions 2.4.17 through 2.4.18, the mod_cgid module failed to properly handle the termination of CGI scripts. The vulnerability allowed a remote attacker to cause a Denial of Service (DoS). Specifically, if a CGI script was killed or terminated abruptly, the module might fail to correctly close the pipe or socket connection to that script. This resulted in a "zombie" process or a resource leak that could eventually exhaust the server’s available process slots or file descriptors. In Apache versions 2
This version was susceptible to attacks where an attacker could potentially decrypt traffic by exploiting how the server handled padding in HTTP/2 .
