Sambar is an All-in-One server for Windows or Linux, that includes servers for irc, ftp, tftp, dns, dhcp etc. A boundary condition error in the /search/results.stm application, can occur during the processing of data received with the POST command. A remote attacker can cause a buffer overflow resulting in a denial of service, and may be able to execute arbitrary code on the system.
