Symantec has issued a patch to plug a vulnerability in its enterprise anti-virus software, which came to light at the end of last week.
The speedy response will stop attackers taking advantage of a flaw which allows internal hackers to take control of enterprise servers.
The flaw, in Version 9 of Symantec’s Anti Virus Corporate Edition product, exposes the server login name and password, along with other security information, when automatic updates to the software are sent by Symantec over the internet.
