high Nessus Plugin ID 100163

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the kde4libs packages.

For the stable distribution (jessie), these problems have been fixed in version 4:4.14.2-5+deb8u2.
