Description Sam James archtester Gentoo Infrastructure gentoo-dev Security 2022-01-03 05:07:26 UTC
A TOCTOU race condition was discovered in shadow-utils. A local attacker with write privileges in a directory removed or copied by usermod/userdel could potentially exploit this flaw, when the administrator invokes usermod/userdel, to delete or modify other files on the system.
