Description:
Some vulnerabilities have been reported in various NetSight products, which can be exploited by malicious people to cause a DoS (Denial of Service) or compromise a vulnerable system.
1) A boundary error in the TFTPD component when processing filenames in request packets can be exploited to cause a stack-based buffer overflow via a specially crafted request packet containing an overly long filename.
2) An error in the BOOTPD component during the handling of the "packet type" field of received packets can be exploited to crash the service.
The vulnerabilities are reported in version 2.1. Other versions may also be affected.
Solution:
Apply Security Patch 1 or update to a fixed version.
