2013-09-10Clarify documentation cross-referenceAllan McRae
The end of the "Parsing of Floats" subsection currently reads: The GNU C Library also provides '_l' versions of these functions, which take an additional argument, the locale to use in conversion. *Note Parsing of Integers::.

The pt-chown binary is discussed in the "Running make install" section without clarification of the needed configure option. Clarify this and simplfy the discription which is already covered in the "Configuring and compiling" section.

2013-07-21CVE-2013-2207, BZ #15755: Disable pt_chown.Carlos O'Donell
The helper binary pt_chown tricked into granting access to another user's pseudo-terminal. Pre-conditions for the attack: * Attacker with local user account * Kernel with FUSE support * "user_allow_other" in /etc/fuse.conf * Victim with allocated slave in /dev/pts Using the setuid installed pt_chown and a weak check on whether a file descriptor is a tty, an attacker could fake a pty check using FUSE and trick pt_chown to grant ownership of a pty descriptor that the current user does not own. It cannot access /dev/pts/ptmx however. In most modern distributions pt_chown is not needed because devpts is enabled by default. The fix for this CVE is to disable building and using pt_chown by default. We still provide a configure option to enable hte use of pt_chown but distributions do so at their own risk.
