Red Hat · Yum · CVE-2014-0022
**Name of the Vulnerable Software and Affected Versions**
yum versions 3.4.3 and earlier
**Description**
The issue allows remote attackers to bypass the RMP package signing restriction, potentially leading to a violation of protected information integrity. This can be exploited remotely. The `installUpdates` function in `yum-cron/yum-cron.py` does not properly check the return value of the `sigCheckPkg` function, enabling the bypass via an unsigned package.
**Recommendations**
For versions 3.4.3 and earlier, as a temporary workaround, consider disabling the `installUpdates` function until a patch is available. Restrict access to unsigned packages to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
