Software: oddjob 0.31.5
OS: Cobalt 7.9

CVE-ID: CVE-2020-10737
CVE-Crit: MEDIUM
CVE-DESC: A race condition was discovered in the mkhomedir tool provided with the oddjob package in versions prior to 0.34.5 and 0.34.6, whereby during the creation of the home directory, mkhomedir copies the / etc / skel directory to the newly created home directory and changes its ownership to the home user without properly checking the homedir path. This flaw allows an attacker to exploit this problem by creating a symbolic link point to the target folder, ownership of which is then transferred to an unprivileged user of the new home directory.
