Synopsis
The remote Oracle Linux host is missing a security update.Description
The remote Oracle Linux 8 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2020-4687 advisory.- A race condition was found in the mkhomedir tool shipped with the oddjob package in versions before 0.34.5 and 0.34.6 wherein, during the home creation, mkhomedir copies the /etc/skel directory into the newly created home and changes its ownership to the home's user without properly checking the homedir path. This flaw allows an attacker to leverage this issue by creating a symlink point to a target folder, which then has its ownership transferred to the new home directory's unprivileged user. (CVE-2020-10737)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
Solution
Update the affected oddjob and / or oddjob-mkhomedir packages.See Also
