-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2008.0181 -- [Win] Symantec Veritas Storage Foundation Scheduler Service DoS Vulnerability 21 February 2008 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: Veritas Storage Foundation for Windows version 5.0 Publisher: iDEFENSE Operating System: Windows Impact: Denial of Service Access: Remote/Unauthenticated CVE Names: CVE-2007-4516 Original Bulletin: http://labs.idefense.com/intelligence/vulnerabilities/ - --------------------------BEGIN INCLUDED TEXT-------------------- iDefense Security Advisory 02.20.08 http://labs.idefense.com/intelligence/vulnerabilities/ Feb 20, 2008 I. BACKGROUND The Veritas Storage Foundation is based on the Veritas File System and Veritas Volume Manager products. It allows virtualization of storage over a variety of platforms. It contains a remote administration application to configure and monitor the elements of the storage network. More information can be found at the following URL. http://www.symantec.com/enterprise/products/overview.jsp?pcid=1020&pvid=203_1 II. DESCRIPTION Remote exploitation of a denial of service vulnerability in Symantec Corp.'s Veritas Storage Foundation scheduler service could allow an unauthenticated attacker to crash the service. When the Veritas Scheduler service (VxSchedService.exe) encounters certain packets, an invalid memory access occurs causing the service to crash. III. ANALYSIS Exploitation of this vulnerability allows remote attackers to cause the affected service to terminate. In order to exploit this vulnerability, an attacker must be able to establish a TCP session with the service on port 4888. No authentication is required to reach the vulnerable code. IV. DETECTION iDefense Labs have confirmed Veritas Storage Foundation for Windows version 5.0 (with VxSchedService.exe version 22.214.171.1248) is vulnerable. It is suspected that all previous versions are vulnerable. V. WORKAROUND Applying filtering to the affected port, such that only hosts which need to use this service can access it, will help mitigate exposure to the vulnerability. VI. VENDOR RESPONSE Symantec has addressed this vulnerability by releasing an update for Veritas Storage Foundation. More information is available in Symantec's advisory at the following URL. http://www.symantec.com/avcenter/security/Content/2008.02.20.html VII. CVE INFORMATION The Common Vulnerabilities and Exposures (CVE) project has assigned the name CVE-2007-4516 to this issue. This is a candidate for inclusion in the CVE list (http://cve.mitre.org/), which standardizes names for security problems. VIII.
