Description

The remote host is affected by the vulnerability described in GLSA-200404-16 (Multiple new security vulnerabilities in monit)

Monit has several vulnerabilities in its HTTP interface : a buffer overflow
vulnerability in the authentication handling code and a off-by-one error in
the POST method handling code.

Impact :

An attacker may exploit the off-by-one error to crash the Monit daemon and
create a denial of service condition, or cause a buffer overflow that would
allow arbitrary code to be executed with root privileges.

Workaround :

A workaround is not currently known for this issue. All users are advised
to upgrade to the latest version of the affected package.
