Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 9 host has packages installed that are affected by a vulnerability as referenced in the dla-2768 advisory.

 - A carefully crafted request uri-path can cause mod_proxy_uwsgi to read above the allocated memory and crash (DoS). This issue affects Apache HTTP Server versions 2.4.30 to 2.4.48 (inclusive). (CVE-2021-36160)

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

Solution

For Debian 9 stretch, this problem has been fixed in version 2.0.14+20161117-3+deb9u4.
