Description Agostino Sarubbo gentoo-dev 2015-07-23 07:40:02 UTC
From ${URL} :

t was reported that if polkit, while reading action descriptions from /usr/share/polkit-1/actions, encounters a duplicate action ID, it corrupts the heap.
The effects of corruption are e.g. visible on stderr as frequent use of unrelated strings when running polkit without --no-debug.

Presumably a local attacker might be able to manipulate polkit’s heap enough to achieve privilege escalation through this.

Upstream bug:

@maintainer(s): after the bump, in case we need to stabilize the package, please let us know if it is ready for the stabilization or not.
Comment 1 Pacho Ramos gentoo-dev 2015-07-23 15:03:59 UTC

this is fixed in 0.113... that should be ok to go to stable as explained at bug 554878
Comment 2 Gilles Dartiguelongue gentoo-dev 2015-12-17 14:26:18 UTC
polkit-0.113 is now stable, must cleanup 0.112-r3.
