Martin Sandsmark reports:

The KAuth framework uses polkit-1 API which tries to authenticate using the requestors PID. This is prone to PID reuse race conditions.

This potentially allows a malicious application to pose as another for authentication purposes when executing privileged actions.

A KDE Security Advisory reports:

kimgio contains a PCX image file format reader that does not properly perform input validation. A source code audit performed by the KDE security team discovered several vulnerabilities in the PCX and other image file format readers, some of them exploitable to execute arbitrary code.

Impact: Remotely supplied, specially crafted image files can be used to execute arbitrary code.

ge 3.2 lt 3.4.0_2

Albert Astals Cid reports:

KAuth contains a logic flaw in which the service invoking dbus is not properly checked. This allows spoofing the identity of the caller and with some carefully crafted calls can lead to gaining root from an unprivileged account.

< 5.33.0_1

The KDE development team reports:

The Konqueror address bar is vulnerable to spoofing attacks that are based on embedding white spaces in the url. In addition the address bar could be tricked to show an URL which it is intending to visit for a short amount of time instead of the current URL.

< 3.5.7_3

< 3.5.7_2

Albert Astals Cid reports:

Using a malicious PAC file, and then using exfiltration methods in the PAC function FindProxyForURL() enables the attacker to expose full https URLs.

This is a security issue since https URLs may contain sensitive information in the URL authentication part (user:password@host), and in the path and the query (e.g. access tokens).

This attack can be carried out remotely (over the LAN) since proxy settings allow "Detect Proxy Configuration Automatically". This setting uses WPAD to retrieve the PAC file, and an attacker who has access to the victim's LAN can interfere with the WPAD protocols (DHCP/DNS+HTTP) and inject his/her own malicious PAC instead of the legitimate one.

David Faure reports:

A maliciously crafted archive (.zip or .tar.bz2) with "../" in the file paths could be offered for download via the KNewStuff framework (e.g. on www.kde-look.org), and upon extraction would install files anywhere in the user's home directory.

< 4.14.10_7

A KDE Security Advisory reports:

Sebastian Krahmer of the SUSE LINUX Security Team reported a local denial of service vulnerability in KDE's Desktop Communication Protocol (DCOP) daemon better known as dcopserver.

A local user can lock up the dcopserver of arbitrary other users on the same machine. This can cause a significant reduction in desktop functionality for the affected users including, but not limited to, the inability to browse the internet and the inability to start new applications.

< 3.4.0

Red Hat reports:

An integer overflow flaw was found in the way Qt handled pixmap images. The KDE khtml library uses Qt in such a way that untrusted parameters could be passed to Qt, triggering the overflow. An attacker could for example create a malicious web page that when viewed by a victim in the Konqueror browser would cause Konqueror to crash or possibly execute arbitrary code with the privileges of the victim.
