Synopsis ========
A vulnerability in KAuth and KDELibs allows local users to gain root privileges.
Background ==========
KAuth provides a convenient, system-integrated way to offload actions that need to be performed as a privileged user (root, for example) to small (hopefully secure) helper utilities.
The KDE libraries, basis of KDE and used by many open source projects.
Affected packages =================
------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 kde-frameworks/kauth < 5.29.0-r1 >= 5.29.0-r1 2 kde-frameworks/kdelibs < 4.14.32 >= 4.14.32 ------------------------------------------------------------------- 2 affected packages
Description ===========
KAuth and KDELibs contains a logic flaw in which the service invoking D-Bus 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.
Impact ======
A local attacker could spoof the identity of the caller invoking D-Bus, possibly resulting in gaining privileges.
Workaround ==========
There is no known workaround at this time.
Resolution ==========
All KAuth users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=kde-frameworks/kauth-5.29.0-r1"
All KDELibs users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=kde-frameworks/kdelibs-4.14.32"
