CVE-2012-6095 proftpd: Symlink race condition when applying UserOwner to a newly (ProFTPD) created directory
A time-of-check time-of-use (TOCTOU) race condition flaw was found in the way ProFTPD, flexible, stable and highly-configurable FTP server, handled MKD/XMKD FTP commands when the UserOwner directive was involved. A local attacker could use this flaw to possibly escalate their privileges via symbolic-link attacks on directories, created by ProFTPD prior UserOwner ownership was applied.
