CVE-2016-10156
Published: 23 January 2017
A flaw in systemd v228 in /src/basic/fs-util.c caused world writable suid files to be created when using the systemd timers features, allowing local attackers to escalate their privileges to root. This is fixed in v229.
Notes
Author | Note |

tyhicks | It looks to me like systemd from the stable phone overlay has the vulnerable code in src/shared/util.c. However, systemd is not used for pid 1 on the phone so marking that specific release as low. |
