Solaris PC Netlink Insecure File Handling
------------------------------------------------------------------------


SUMMARY

" <http://www.sun.com/solaris/> Solaris PC
<http://www.sun.com/products/interoperability/netlink/> NetLink software
(based on AT&T Advanced Server for Unix) delivers native Windows NT
network services--which include directory, authentication, and
file-and-print services--on Solaris environment servers."

A vulnerability within PC Netlink allows locally stored files to be opened
insecurely and possibly modified.

DETAILS

Vulnerable Systems:
* PC NetLink 2.0 (for Solaris 7, 8 and 9) without patch 121209-01

Immune Systems:
* PC NetLink 2.0 (for Solaris 7, 8 and 9) with patch 121209-01 or later

A security vulnerability in the "/opt/lanman/sbin/slsmgr" and
"/etc/init.d/slsadmin" command in PC NetLink allows files to be opened
insecurely, which could allow an unprivileged local user the ability to
write to the filesystem with the permissions of the user running the
script. If the script is run as "root," it may allow a local unprivileged
user to gain elevated privileges on the system and run arbitrary commands.
