Debian DLA-2450-1 : libproxy security update

critical Nessus Plugin ID 142931

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Li Fei found that libproxy, a library for automatic proxy configuration management, was vulnerable to a buffer overflow vulnerability when receiving a large PAC file from a server without a Content-Length header in the response.

For Debian 9 stretch, this problem has been fixed in version 0.4.14-2+deb9u2.

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.
