Oracle Linux 8 : httpd:2.4 (ELSA-2020-3714)

high Nessus Plugin ID 140525

Language:

Synopsis

The remote Oracle Linux host is missing a security update.

Description

The remote Oracle Linux 8 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2020-3714 advisory.

 - Apache HTTP Server versions 2.4.20 to 2.4.43. A specially crafted value for the 'Cache-Digest' header in a HTTP/2 request would result in a crash when the server actually tries to HTTP/2 PUSH a resource afterwards. Configuring the HTTP/2 feature via H2Push off will mitigate this vulnerability for unpatched servers. (CVE-2020-9490)

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

Solution

Update the affected packages.
