Technical Description

Gentoo has released a security patch to correct a vulnerability identified in Util-Linux. This flaw is due to a design error in the "-r" option that improperly clears mounted-filesystem options, which could be exploited by malicious users to cause the nosuid, noexec, and nodev flags to be cleared, allowing them to gain root privileges. For additional information, see : VUPEN/ADV-2005-1728
