CVE-2014-0022: Baseurl Yum

Medium severity, CVSS 5.0. EPSS: 2.4% chance of exploitation in the next 30 days.

The installUpdates function in yum-cron/yum-cron.py in yum 3.4.3 and earlier does not properly check the return value of the sigCheckPkg function, which allows remote attackers to bypass the RMP package signing restriction via an unsigned package.

Affected products
