DESCRIPTION:
Some vulnerabilities have been reported in the Generic SCSI Target
Subsystem For Linux (SCST), which can be exploited by malicious
people to cause a DoS (Denial of Service) and potentially compromise
a vulnerable system.

The vulnerabilities are caused due to a boundary errors when
processing certain iSNS (Internet Storage Name Service) messages,
which can be exploited to cause buffer overflows by sending specially
crafted messages.

Successful exploitation may allow the execution of arbitrary code.

This is related to:
SA40485

The vulnerabilities are reported in version 1.0.1.1. Other versions
may also be affected.

SOLUTION:
Fixed in the SVN repository.

PROVIDED AND/OR DISCOVERED BY:
