Description: Brett Moore has reported a vulnerability in Microsoft Windows, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a boundary error in the HyperTerminal application when processing session files and telnet URLs. This can be exploited to cause a heap-based buffer overflow by tricking a user into opening a malicious HyperTerminal session file (.ht) or clicking a specially crafted telnet URL in a malicious e-mail or on a web site.
Successful exploitation allows execution of arbitrary code.
NOTE: Exploitation via a telnet URL requires that HyperTerminal is set as the default telnet client (not default setting).
