Synopsis
========
Two new vulnerabilities have been found in the HTTP interface of monit,
possibly leading to denial of service or execution of arbitrary code.
Background
==========
Monit is a system administration utility that allows management and
monitoring of processes, files, directories and devices on a Unix
system.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
app-admin/monit <= 4.2 >= 4.2.1
Description
===========
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.
Resolution
==========
Monit users should upgrade to version 4.2.1 or later:
# emerge sync
# emerge -pv ">=app-admin/monit-4.2.1"
# emerge ">=app-admin/monit-4.2.1"
