FreeBSD : Apache httpd -- multiple vulnerabilities (8e6f684b-f333-11ee-a573-84a93843eb75)

high Nessus Plugin ID 192960

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the 8e6f684b-f333-11ee-a573-84a93843eb75 advisory.

 - HTTP Response splitting in multiple modules in Apache HTTP Server allows an attacker that can inject malicious response headers into backend applications to cause an HTTP desynchronization attack. Users are recommended to upgrade to version 2.4.59, which fixes this issue. (CVE-2024-24795)

 - HTTP/2 incoming headers exceeding the limit are temporarily buffered in nghttp2 in order to generate an informative HTTP 413 response. If a client does not stop sending headers, this leads to memory exhaustion.
 (CVE-2024-27316)

 - The Apache httpd project reports: HTTP/2 DoS by memory exhaustion on endless continuation frames HTTP Response Splitting in multiple modules (CVE-2024-38709)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
