Name of the Vulnerable Software and Affected Versions mgetty versions prior to 1.2.1

Description An issue in the fax notify mail function in faxrec.c allows for a buffer overflow due to the mail to parameter not being sanitized. This could potentially lead to a denial of service if long untrusted input reaches it. The exploitation of this issue may cause a stack-based buffer overflow, allowing an attacker to disrupt service using the mail to parameter.

Recommendations For versions prior to 1.2.1, update to version 1.2.1 or later to resolve the issue. As a temporary workaround, consider restricting input to the fax notify mail function to prevent long untrusted input from reaching the mail to parameter.
