Debian DLA-1275-1 : uwsgi security update

critical Nessus Plugin ID 106723

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that the uwsgi_expand_path function in utils.c in Unbit uWSGI, an application container server, has a stack-based buffer overflow via a large directory length that can cause a denial of service (application crash) or stack corruption.

For Debian 7 'Wheezy', these problems have been fixed in version 1.2.3+dfsg-5+deb7u2.

We recommend that you upgrade your uwsgi packages.

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.
