Ubuntu Security Notice USN-75-1
4th February, 2005
cpio vulnerability
A security issue affects these releases of Ubuntu and its derivatives:
- 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.
Update instructions
The problem can be corrected by updating your system to the following package version:
- Ubuntu 4.10:
- cpio
