Subject: MDKSA-2004:031 - Updated utempter packages fix several vulnerabilities
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
_______________________________________________________________________
Mandrakelinux Security Update Advisory
_______________________________________________________________________
Package name: utempter
Advisory ID: MDKSA-2004:031
Date: April 19th, 2004
Affected versions: 10.0, 9.1, 9.2, Corporate Server 2.1,
Multi Network Firewall 8.2
______________________________________________________________________
Problem Description:
Steve Grubb discovered two potential issues in the utempter program:
1) If the path to the device contained /../ or /./ or //, the
program was not exiting as it should. It would be possible to use something
like /dev/../tmp/tty0, and then if /tmp/tty0 were deleted and symlinked
to another important file, programs that have root privileges that do no
further validation can then overwrite whatever the symlink pointed to.
2) Several calls to strncpy without a manual termination of the string.
This would most likely crash utempter.
The updated packages are patched to correct these problems.
