Amazon Linux AMI : httpd24 (ALAS-2024-1931)

high Nessus Plugin ID 194722

Language:

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

The version of httpd24 installed on the remote host is prior to 2.4.59-1.102. It is, therefore, affected by a vulnerability as referenced in the ALAS-2024-1931 advisory.

 - 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)

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

Solution

Run 'yum update httpd24' to update your system.
