Debian: Security update for libproxy

The Red Hat Security Response Team discovered that libproxy, a library for automatic proxy configuration management, applied insufficient validation to the Content-Length header sent by a server providing a proxy.pac file. Such remote server could trigger an integer overflow and consequently overflow an in-memory buffer.

Updated packages are available from security.debian.org.
