CVE ID : CVE-2013-2074 CVE-2017-6410 CVE-2017-8422
Debian Bug : 856890

Several vulnerabilities were discovered in kde4libs, the core libraries
for all KDE 4 applications. The Common Vulnerabilities and Exposures
project identifies the following problems:

CVE-2017-6410

Itzik Kotler, Yonatan Fridburg and Amit Klein of Safebreach Labs
reported that URLs are not sanitized before passing them to
FindProxyForURL, potentially allowing a remote attacker to obtain
sensitive information via a crafted PAC file.

CVE-2017-8422

Sebastian Krahmer from SUSE discovered that the KAuth framework
contains a logic flaw in which the service invoking dbus is not
properly checked. This flaw allows spoofing the identity of the
caller and gaining root privileges from an unprivileged account.

CVE-2013-2074

It was discovered that KIO would show web authentication
credentials in some error cases.

For Debian 7 "Wheezy", these problems have been fixed in version
4:4.8.4-4+deb7u3.

We recommend that you upgrade your kde4libs packages.
