PLATFORM: SPARC Platform Solstice Backup (SBU) 6.0 Solstice Backup (SBU) 6.1 Sun StorEdge Enterprise Backup Software (EBS) 7.1 without patch 116826-06 Sun StorEdge Enterprise Backup Software (EBS) 7.1L without patch 116828-04 Sun StorEdge Enterprise Backup Software (EBS) 7.2 (32 bit) Sun StorEdge Enterprise Backup Software (EBS) 7.2 (64 bit) Sun StorEdge Enterprise Backup Software (EBS) 7.2L x86 Platform Solstice Backup (SBU) 6.0 Solstice Backup (SBU) 6.1 Sun StorEdge Enterprise Backup Software (EBS) 7.1 without patch 116827-07 Sun StorEdge Enterprise Backup Software (EBS) 7.2 Note: These issues are known to affect all Sun StorEdge Enterprise Backup Software (EBS) versions prior to 7.3 release. DAMAGE: Two of the vulnerabilities could permit a local or remote unauthorized user to gain access to a host system and execute arbitrary code. One may allow a local or remote unauthenticated user to cause a system crash on the server, which would lead to a Denial of Service (DoS) condition. SOLUTION: Upgrade to the appropriate version. ______________________________________________________________________________ VULNERABILITY The risk is HIGH. Legato server runs as root. A buffer overflow ASSESSMENT: in the Sun StorEdge (Legato) Backup Server could allow a remote attacker to run arbitrary code as root. ______________________________________________________________________________ LINKS: CIAC BULLETIN: http://www.ciac.org/ciac/bulletins/q-109.shtml ORIGINAL BULLETIN: Sun Alert ID: 102148 http://www.sunsolve.sun.com/search/document.do?assetkey=1 -26-102148-1&searchclause=%22category:security%22%20%22 availability,%20security%22%20category:security CVE: http://www.cve.mitre.org/cgi-bin/cvename.cgi?name= CAN-2005-3658 CAN-2005-3659 ______________________________________________________________________________ REVISION HISTORY: 01/30/2006 - reflect the changes Sun has made in Sun Alert ID: 102148 where they have updated the Contributing Factors and Resolution section, and re-release Resolved.

Impact There are three vulnerabilities in Sun StorEdge Enterprise Backup Software (EBS), which affect both the client and server applications. Two of the vulnerabilities could permit a local or remote unauthorized user to gain access to a host system and execute arbitrary code. One may allow a local or remote unauthenticated user to cause a system crash on the server, which would lead to a Denial of Service (DoS) condition. Note: To date there are no reported incidences of this issue having occurred in a "live" (public) environment. These issues are referenced in the following iDEFENSE (http://www.idefense.com) documents: IDEF1237 "...Networker nsrd.exe DoS Vulnerability" at http://www.idefense.com/ intelligence/vulnerabilities/display.php?id=375 IDEF1238 "...Networker nsrexecd.exe Heap Overflow Vulnerability" at http://www. idefense.com/intelligence/vulnerabilities/display.php?id=374 IDEF1239 "...Networker nsrd.exe Heap Overflow Vulnerability" at http://www.idefense. com/intelligence/vulnerabilities/display.php?id=373 and also CAN-2005-3658 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-3658 CAN-2005-3659 at http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2005-3659 2. Contributing Factors These issues can occur in the following releases: SPARC Platform Solstice Backup (SBU) 6.0 Solstice Backup (SBU) 6.1 Sun StorEdge Enterprise Backup Software (EBS) 7.1 without patch 116826-06 Sun StorEdge Enterprise Backup Software (EBS) 7.1L without patch 116828-04 Sun StorEdge Enterprise Backup Software (EBS) 7.2 (32 bit) without patch 120650-01 Sun StorEdge Enterprise Backup Software (EBS) 7.2 (64 bit) without patch 120651-01 Sun StorEdge Enterprise Backup Software (EBS) 7.2L without patch 120653-01 x86 Platform Solstice Backup (SBU) 6.0 Solstice Backup (SBU) 6.1 Sun StorEdge Enterprise Backup Software (EBS) 7.1 without patch 116827-07 Sun StorEdge Enterprise Backup Software (EBS) 7.2 without patch 120652-01 Note: These issues are known to affect all Sun StorEdge Enterprise Backup Software (EBS) versions prior to 7.3 release. To determine if Solstice Backup (SBU) is installed on a system, the following command can be run: $ pkginfo | grep SUNWsbu To determine the version of Solstice Backup (SBU) on a system, the following command can be run: $ pkginfo -l SUNWsbuX (where 'X' is one of the last characters of the EBS package names found from the above pkginfo(1) command). To determine if Sun StorEdge EBS is installed on a system, the following command can be run: $ pkginfo | grep SUNWebs To determine the version of Sun StorEdge EBS on a system, the following command can be run: $ pkginfo -l SUNWebsX (where 'X' is one of the last characters of the EBS package names found from the above pkginfo(1) command). 3. Symptoms There are no reliable symptoms that would indicate the described issues have been exploited. Solution Summary Top 4. Relief/Workaround There is no workaround to these issues.
