GLSA 200403-14: Multiple Security Vulnerabilities in Monit

http://security.gentoo.org/

Severity:	high
Title:	Multiple Security Vulnerabilities in Monit
Date:	03/31/2004
Bugs:	#43967
ID:	200403-14

Synopsis

A denial of service and a buffer overflow vulnerability have been found in Monit.

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	Architecture(s)
app-admin/monit	<= 4.1	>= 4.2	All supported architectures

Description

A denial of service may occur due to Monit not sanitizing remotely supplied HTTP parameters before passing them to memory allocation functions. This could allow an attacker to cause an unexpected condition that could lead to the Monit daemon crashing.

An overly long http request method may cause a buffer overflow due to Monit performing insufficient bounds checking when handling HTTP requests.

Impact

An attacker may crash the Monit daemon to 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 or later:

 
    # emerge sync
    
    # emerge -pv ">=app-admin/monit-4.2"
    # emerge ">=app-admin/monit-4.2"
