2013-09-10Clarify documentation cross-referenceAllan McRae1-1/+2
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::.

2013-07-21CVE-2013-2207, BZ #15755: Disable pt_chown.Carlos O'Donell1-0/+14
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.
