Description

The lprm command of the printing package lprold shipped till SUSE 7.3 contains a buffer overflow. This buffer overflow can be exploited by a local user, if the printer system is set up correctly, to gain root privileges. lprold is installed as default package and has the setuid bit set.

As a temporary workaround you can disable the setuid bit of lprm by executing the following tasks as root:

add "/usr/bin/lprm root.root 755" to /etc/permissions.local
run 'chkstat -set /etc/permissions.local' Another way would be to just allow trusted users to run lprm by executing the following tasks as root:
add "/usr/bin/lprm root.trusted 4750" to /etc/permissions.local
run 'chkstat -set /etc/permissions.local'

Please download the update package for your distribution and verify its integrity by the methods listed in section 3) of this announcement. Then, install the package using the command "rpm -Fhv file.rpm" to apply the update. Our maintenance customers are being notified individually. The packages are being offered to install from the maintenance web.
