=========================================================== Ubuntu Security Notice USN-75-1 February 04, 2005 cpio vulnerability CAN-1999-1572 =========================================================== A security issue affects the following Ubuntu releases: Ubuntu 4.10 (Warty Warthog) The following packages are affected: cpio The problem can be corrected by upgrading the affected package to version 2.5-1.1ubuntu0.1. In general, a standard system upgrade is sufficient to effect the necessary changes. Details follow: Recently it was discovered that cpio created world-writeable files when used in -o/--create mode with giving an output file (with -O). This allowed any user to modify the created cpio archives. Now cpio respects the current umask setting of the user. Note: This vulnerability has already been fixed in a very old version of cpio, but the fix was never ported to the current version. Therefore the CAN number was assigned to the year 1999.
