Debian DLA-2768-1 : uwsgi - LTS security update

high Nessus Plugin ID 153843

Language:

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.

 It was discovered that the uwsgi proxy module for Apache2 (mod_proxy_uwsgi) can read above the allocated memory when processing a request with a carefully crafted uri-path. An attacker may cause the server to crash (DoS). For Debian 9 stretch, this problem has been fixed in version 2.0.14+20161117-3+deb9u4. 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 Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS

Tenable has extracted the preceding description block directly from the Debian security advisory.

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

Solution

Upgrade the uwsgi packages.

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