Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that there was a denial of service attack in libproxy, a library to make applications HTTP proxy aware. A remote server could cause an infinite stack recursion.

For Debian 9 'Stretch', this problem has been fixed in version 0.4.14-2+deb9u1.

We recommend that you upgrade your libproxy packages.

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

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.
