Description Laura Pardo 2018-03-28 17:05:12 UTC

The main function in android_main.cpp in thermald allows local users to write to arbitrary files via a symlink attack on /tmp/thermald.pid on systems that lack of symlink and hardlink protections in world-writable directories

Created thermald tracking bugs for this issue:

Affects: fedora-all [bug 1561686]
Affects: epel-7 [bug 1561685]

Comment 2 Benjamin Berg 2019-05-17 15:24:58 UTC

This CVE is specific to code that is only used on Android. In other cases the code in main.cpp is used which creates the PID file in /var/run/thermald, AFAICT there is no privilege escalation there as normal users are unable to write the location.
