Multiple new security vulnerabilities in monit — GLSA 200404-16

Two new vulnerabilities have been found in the HTTP interface of monit, possibly leading to denial of service or execution of arbitrary code.

Affected packages

Package 	app-admin/monit on all architectures
Affected versions 	<= 4.2
Unaffected versions 	>= 4.2.1

Background

Monit is a system administration utility that allows management and monitoring of processes, files, directories and devices on a Unix system.

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"
