Date of Resolved Release
A race condition vulnerability in handling recursive directory deletion via the rm(1) command with either the "-r" or "-R" option may lead to deletion of files or directories external to the argument directory hierarchy. An unprivileged user may exploit this vulnerability by creating a specially crafted directory hierarchy which, when deleted by a privileged user using the rm(1) command, may lead to deletion of system files and directories causing a Denial of Service (DoS) condition.
