Synopsis

The remote FreeBSD host is missing a security-related update.

Description

Qualys reports :

During the code review of OpenSMTPD a memory leak and buffer overflow (an off-by-one, usually stack-based) were discovered in LibreSSL's OBJ_obj2txt() function. This function is called automatically during a TLS handshake (both client-side, unless an anonymous mode is used, and server-side, if client authentication is requested).

Solution

Update the affected package.
