-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2009.0380 -- [Solaris] Veritas NetBackup: Increased Privileges 20 April 2009 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: Veritas NetBackup 6.0 Veritas NetBackup 6.5 Publisher: Sun Microsystems Operating System: Solaris Impact: Increased Privileges Access: Existing Account Ref: AA-2009.0032 Original Bulletin: http://sunsolve.sun.com/search/printfriendly.do?assetkey=1-66-253287-1 - --------------------------BEGIN INCLUDED TEXT-------------------- Solution Type: Sun Alert Solution 253287 : Security Vulnerability in the VERITAS (Symantec) NetBackup Network Daemon may Allow Escalation of Privileges Bug ID: 6803212, 6803215, 6797673, 6797674 Product Veritas NetBackup 6.0 Veritas NetBackup 6.5 Date of Resolved Release: 16-Apr-2009 SA Document Body Security Vulnerability in the VERITAS (Symantec) NetBackup network daemon may allow escalation of privileges: 1. Impact A Security Vulnerability in the VERITAS (Symantec) NetBackup network daemon may allow an unprivileged local user to leverage the Veritas network daemon (vnetd) to gain elevated privileges on the system. This issue is referenced in Symantec Security Advisory SYM09-002 at: * http://seer.entsupport.symantec.com/docs/317828.htm 2. Contributing Factors This issue can occur in the following releases: SPARC Platform * VERITAS (Symantec) NetBackup 6.0 GA version without patch 136859-01 * VERITAS (Symantec) NetBackup 6.0 MP4 CD version without patch 136860-01 * VERITAS (Symantec) NetBackup 6.5 without patch 136863-01 x86 Platform * VERITAS (Symantec) NetBackup 6.5 without patch 136864-01 Note 1: NetBackup 5.x and earlier versions are no longer supported and will require an upgrade to a later supported version with the appropriate patches to resolve this issue. Note 2: NetBackup 6.0 and earlier versions are not shipped for the x86 Platform. Note 3: To determine if a system is running the 6.0 GA version or the 6.0 MP4 CD version, execute the following command: $ pkgparam VRTSnetbp VERSION VERSION=6.0,REV=2005.09.07.19.13 The 6.0 GA version responds with VERSION=6.0,REV=2005.09.07.19.13 The 6.0 MP4 CD version responds with VERSION=6.0,REV=2006.11.09.18.12 3. Symptoms There are no predictable symptoms to indicate that the described issue has been exploited to gain elevated privileges. 4. Workaround Sites unable to update immediately to the recommended solution should restrict inbound access to the vnetd listening port (TCP/13724) on all systems. This may be done by using firewall applications on the affected systems. Please refer to the firewall documentation on how to setup the access authorizations. Normal operations should restrict client to client communications and allow master server to media server, media server to media server, and master/media server to client communications only. As part of normal best practices, Symantec strongly recommends the following: * Restrict access to administration or management systems to privileged users. * Restrict remote access, if it is required, to trusted/authorized systems only. * Run under the principle of least privilege where possible to limit the impact of potential exploits. * Keep all operating systems and applications updated with the latest vendor patches. * Follow a multi-layered approach to security. Run both firewall and antivirus applications, at a minimum, to provide multiple points of detection and protection to both inbound and outbound threats. * Deploy network intrusion detection systems to monitor network traffic for signs of anomalous or suspicious activity. This may aid in detection of attacks or malicious activity related to exploitation of latent vulnerabilities. 5. Resolution This issue is addressed in the following releases: SPARC Platform * VERITAS (Symantec) NetBackup 6.0 GA version with patch 136859-01 or later * VERITAS (Symantec) NetBackup 6.0 MP4 CD version with patch 136860-01 or later * VERITAS (Symantec) NetBackup 6.5 with patch 136863-01 or later x86 Platform * VERITAS (Symantec) NetBackup 6.5 with patch 136864-01 or later Notes: Patches 136859-01 and 136860-01 have identical binaries, with the only difference being the version of VRTSnetbp being patched. Only one of the patches will be applied to a NetBackup system based on the following: Patch 136859-01 is applicable to VERITAS NetBackup 6.0 Product for GA, with version string VERSION=6.0,REV=2005.09.07.19.13. Patch 136860-01 is applicable to VERITAS NetBackup 6.0 MP4 CD with version string VERSION=6.0,REV=2006.11.09.18.12. For more information on Security Sun Alerts, see Technical Instruction ID 213557.
