- Date Reported:
- 25 May 2017
- Affected Packages:
- Security database references:
- In the Debian bugtracking system: Bug 856890.
In Mitre's CVE dictionary: CVE-2013-2074, CVE-2017-6410, CVE-2017-8422.
- 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:
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.
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.
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.
