/usr/local/flexlm
SYSTEMS AFFECTED
Systems using FLEXlm
PROBLEM
Due to some confusion in the documentation supplied to vendors
using the FLEXlm package, the FLEXlm licence management software
often runs with root privileges. This often occurs due to the
FLEXlm daemons being started by the system initialisation
scripts. If the daemons are running with root privileges they
may be used by local users to gain unauthorised root privileges.
This potentially affects all versions of the FLEXlm licence
management daemon.
A vulnerability has been also found in the FLEXlm licence
management daemon which may allow local users unauthorised access
to the account running the FLEXlm licence management daemon. This
vulnerability exists in all versions of the FLEXlm licence
management daemon from version 4.0 up to, and including, version
5.0a.
SOLUTION
GLOBEtrotter Software advise that the FLEXlm licence management
software does not require root privileges to operate. The FLEXlm
licence management daemon should be run by a non-privileged user.
All versions of the FLEXlm licence management daemon from version
4.0 up to, and including, version 5.0a should be upgraded
immediately (latest version 5.0b).
