Multiple heap-based buffer overflows in EMC Legato NetWorker 7.1.x before 7.1.4 and 7.2.x before 7.2.1.Build.314, and other products such as Sun Solstice Backup (SBU) 6.0 and 6.1 and StorEdge Enterprise Backup Software (EBS) 7.1 through 7.2L, allow remote attackers to execute arbitrary code or cause a denial of service (unresponsive application) via malformed RPC packets to (1) RPC program number 390109 (nsrd.exe) and (2) RPC program number 390113 (nsrexecd.exe).

EMC Legato NetWorker, Sun Solstice Backup 6.0 and 6.1, and StorEdge Enterprise Backup 7.0 through 7.2 rely on AUTH_UNIX authentication, which relies on user ID for authentication and allows remote attackers to bypass authentication and gain privileges by spoofing a username or UID.

The Legato PortMapper in EMC Legato NetWorker, Sun Solstice Backup 6.0 and 6.1, and StorEdge Enterprise Backup 7.0 through 7.2 does not restrict access to the pmap_set and pmap_unset commands, which allows remote attackers to (1) cause a denial of service by using pmap_unset to un-register a NetWorker service, or (2) obtain sensitive information from NetWorker services by using pmap_set to register a new service.

EMC Legato NetWorker, Solstice Backup 6.0 and 6.1, and StorEdge Enterprise Backup 6.0 through 7.2 do not properly verify authentication tokens, which allows remote attackers to gain privileges by modifying an authentication token.

Worker Filemanager 1.0 through 2.7 sets the permissions on the destination directory to world-readable and executable while copying data, which could allow local users to obtain sensitive information.

nsr_shutdown in Fujitsu Siemens NetWorker 6.0 allows local users to overwrite arbitrary files via a symlink attack on the nsrsh[PID] temporary file.

EMC NetWorker (formerly Legato NetWorker) before 7.0 stores log files in the /nsr/logs/ directory with world-readable permissions, which allows local users to read sensitive information and possibly gain privileges. NOTE: this was originally reported for Legato NetWorker 6.1 on the Solaris 7 platform.

EMC NetWorker (formerly Legato NetWorker) before 7.0 stores passwords in plaintext in the daemon.log file, which allows local users to gain privileges by reading the password from the file. NOTE: this was originally reported for Legato NetWorker 6.1 on the Solaris 7 platform.

Legato Networker before 6.1 allows remote attackers to bypass access restrictions and gain privileges on the Networker interface by spoofing the admin server name and IP address and connecting to Networker from an IP address whose hostname can not be determined by a DNS reverse lookup.
