Debian DSA-4142-1 : uwsgi - security update

high Nessus Plugin ID 108419

Language:

Synopsis

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

Description

Marios Nicolaides discovered that the PHP plugin in uWSGI, a fast, self-healing application container server, does not properly handle a DOCUMENT_ROOT check during use of the --php-docroot option, allowing a remote attacker to mount a directory traversal attack and gain unauthorized read access to sensitive files located outside of the web root directory.

Solution

Upgrade the uwsgi packages.

For the oldstable distribution (jessie), this problem has been fixed in version 2.0.7-1+deb8u2. This update additionally includes the fix for CVE-2018-6758 which was aimed to be addressed in the upcoming jessie point release.

For the stable distribution (stretch), this problem has been fixed in version 2.0.14+20161117-3+deb9u2.
