cpio vulnerability

Releases

• Ubuntu 4.10

Details

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.
