EMC has issued three patches for flaws in its NetWorker products, and code that takes advantage of a previously reported flaw in Veritas' NetBackup product has been publicly released on the internet.
With the EMC NetWorker flaws, users could either face a system crash or the threat of an attacker taking over the system, according to the company.
The three vulnerabilities in NetWorker 7.2.1 were reported to EMC by security researcher iDefense. Both earlier and later versions of the product are not believed to be vulnerable.
Meanwhile, companies that have not already patched against a flaw in Veritas NetBackup, that was first reported last November, face an attack as a result of code that takes advantage of the flaw being released on the internet.
Symantec, which owns Veritas, issued a patch for the problem last year, and is urging customers to act now.
The NetBackup vulnerability can again lead to a system crash or an attacker taking over the system.
The affected products are versions 5.0.0 and 5.1.0 of the NetBackup Client, NetBackup Enterprise Server and NetBackup Server.
