Description

glibc security update :

CVE-2013-2207 glibc (pt_chown): Improper pseudotty ownership and permissions changes when granting access to the slave pseudoterminal

The fix may break chroots if their devpts was not mounted correctly. Fix is to mount the devpts correctly with gid=5.

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.
