Discussion

Heimdal TelnetD Remote Buffer Overflow Vulnerability

Heimdal telnetd is susceptible to a remote buffer overflow vulnerability. This issue is due to a failure of the application to properly bounds check user-supplied data prior to copying it to an insufficiently sized memory buffer.

This vulnerability may be exploited by remote attackers to influence the proper flow of execution of the application, resulting in attacker-supplied machine code being executed in the context of the affected network service.
