CVE-2015-0245

Publication date 13 February 2015

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

D-Bus 1.4.x through 1.6.x before 1.6.30, 1.8.x before 1.8.16, and 1.9.x before 1.9.10 does not validate the source of ActivationFailure signals, which allows local users to cause a denial of service (activation failure error returned) by leveraging a race condition involving sending an ActivationFailure signal before systemd responds.

Notes

seth-arnold

The policy change is recommended for stable use, though the code-based changes were made for platforms where uid==0 may not be omnipotent -- we should probably use both in our packages, or at least both for the versions with distro-patched AppArmor support.
