More information:

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.
