Title: EMC Legato Networker Multiple Remote Vulnerabilities
Severity: CRITICAL
Description:
Legato NetWorker is a server package designed to help share data, media, and backup processes across a heterogeneous network. The Legato NetWorker server will run on a number of Unix variants and on Microsoft Windows NT/2000 systems.
EMC Legato NetWorker is affected by multiple remote vulnerabilities. A denial-of-service issue and two remote code-execution issues have been identified.
One issue is reported to be caused by insufficient sanity-checking in authentication parameters.
The other two issues arise from heap-overflow conditions and affect the 'nsrd.exe' and 'nsrexecd.exe' processes:
- 'nsrd.exe' process -- malformed RPC requests to RPC program number 390109 can trigger an overflow.
- 'nsrexecd.exe' process -- malformed RPC requests to RPC program number 390113 can trigger an overflow.
These processes are installed on both clients and servers.
Version 7.2.1 of Legato NetWorker is vulnerable to these issues; prior versions may also be affected.
