Debian DLA-2362-1 : uwsgi security update

critical Nessus Plugin ID 140224

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Apache HTTP Server versions before 2.4.32 uses src:uwsgi where a flaw was discovered. The uwsgi protocol does not let us serialize more than 16K of HTTP header leading to resource exhaustion and denial of service.

For Debian 9 stretch, this problem has been fixed in version 2.0.14+20161117-3+deb9u3.

We recommend that you upgrade your uwsgi packages.

For the detailed security status of uwsgi please refer to its security tracker page at: https://security-tracker.debian.org/tracker/uwsgi

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
