~ VMware Security Advisory
Advisory ID: VMSA-2008-0007
Synopsis: Moderate Updated Service Console packages pcre
~ net-snmp, and OpenPegasus
Issue date: 2008-04-15
Updated on: 2008-04-15 (initial release of advisory)
CVE numbers: CVE-2006-7228 CVE-2007-1660 CVE-2007-5846
~ CVE-2008-0003
- -------------------------------------------------------------------
1. Summary:
~ Updated Service Console packages for pcre, net-snmp, and OpenPegasus
2. Relevant releases:
~ VMware ESX 3.5 without patch ESX350-200803214-UG
3. Problem description:
~ a. Updated pcre Service Console package addresses several security issues
~ The pcre package contains the Perl-Compatible Regular Expression library.
~ pcre is used by various Service Console utilities.
~ Several security issues were discovered in the way PCRE handles
~ regular expressions. If an application linked against PCRE parsed a
~ malicious regular expression, it may have been possible to run
~ arbitrary code as the user running the application.
~ VMware would like to thank Ludwig Nussel for reporting these issues.
~ The Common Vulnerabilities and Exposures project (cve.mitre.org) has
~ assigned the names CVE-2006-7228 and CVE-2007-1660 to these issues.
~ RPM Updated:
~ pcre-3.9-10.4.i386.rpm
~ b. Updated net-snmp Service Console package addresses denial of service
~ net-snmp is an implementation of the Simple Network Management
~ Protocol (SNMP). SNMP is used by network management systems to
~ monitor hosts. By default ESX has this service enabled and its ports
~ open on the ESX firewall.
~ A flaw was discovered in the way net-snmp handled certain requests. A
~ remote attacker who can connect to the snmpd UDP port could send a
~ malicious packet causing snmpd to crash, resulting in a denial of
~ service.
~ The Common Vulnerabilities and Exposures project (cve.mitre.org) has
~ assigned the name CVE-2007-5846 to this issue.
~ RPM Updated:
~ net-snmp-5.0.9-2.30E.23.i386.rpm
~ net-snmp-libs-5.0.9-2.30E.23.i386.rpm
~ net-snmp-utils-5.0.9-2.30E.23.i386.rpm
~ c. Updated OpenPegasus Service Console package fixes overflow condition
~ OpenPegasus is a CIM (Common Information Model) and Web-Based Enterprise
~ Management (WBEM) broker. These protocols are used by network management
~ systems to monitor and control hosts. By default ESX has this service
~ enabled and its ports open on the ESX firewall.
~ A flaw was discovered in the OpenPegasus CIM management server that
~ might allow remote attackers to execute arbitrary code. OpenPegasus
~ when compiled to use PAM and without PEGASUS_USE_PAM_STANDALONE_PROC
~ defined, has a stack-based buffer overflow condition.
~ The Common Vulnerabilities and Exposures project (cve.mitre.org) has
~ assigned the name CVE-2008-0003 to this issue.
~ RPMS updated:
~ cim-smwg-1.0-release-606113.i386.rpm
~ pegasus-2.5-release-606113.i386.rpm
