+Submitted By: Ken Moffat <ken@kenmoffat.uklinux.net>
+Date: 2005-07-29
+Initial Package Version: 2.6
+Upstream Status: Unknown
+Origin: from Mandrake
+Description: Vulnerability fixes, rediffed so that they all apply with
+ -p1 and consolidated to single patch. Also applicable to earlier versions.
+(1.) CAN-1999-1572 (still seems to apply to 2.6) cpio uses a 0 umask when
+creating files with -O or -F options, which creates the files with mode 0666
+and allows local users to overwrite them. Fix originally fom debian.
+(2.) CAN-2005-1111 Race condition in 2.6 and earlier allows local users to
+modify permissions of arbitrary files via a hard-link attack. Fix
+originally from fedora.
+(3.) CAN-2005-1229 Directory traversal vulnerability allows remote
+attackers to write to arbitrary directories via a dot dot in a cpio file.
+Fix by Peter Vrabec at RedHat.
