Two vulnerabilities have been reported in Backup and Restore Utility for Unix (BRU), which can be exploited by malicious, local users to escalate their privileges on a vulnerable system.

Both vulnerabilities are caused due to erroneous handling of command line parameters. A boundary error exists, which can be exploited by supplying an overly long (3050 characters), specially crafted command line argument. A format string error also exists, which can be exploited by supplying specially crafted arguments containing format specifiers.

Successful exploitation of the two vulnerabilities will allow execution of arbitrary code with "root" privileges.

The vulnerabilities have been reported in version 17.0 and prior. However, according to the original advisory only the older version from Enhanced Software Technologies (EST) was shipped with the suid bit set (not the one from the TOLIS Group).

Solution
Remove the suid bit.
