Description

This update is a security update fixing two local privilege escalation problems. mod_suphp 0.6.2 contains two race condition regarding symlink checks. Using this attack vector a local attacker has the ability of changing symlinks in the timeframe between the security check and the php execution itself, leading suphp to execute code as another local user. These have been fixed in the 0.6.3 update with no further code changes being present making a backport of the security fix unnecessary.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
