CVE-2015-2285
The logrotation script (/etc/cron.daily/upstart) in the Ubuntu Upstart package before 1.13.2-0ubuntu9, as used in Ubuntu Vivid 15.04, allows local users to execute arbitrary commands and gain privileges via a crafted file in /run/user/*/upstart/sessions/.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.01%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
