Sophos software hit by security threat

Security software company Sophos has warned companies of a security vulnerability affecting a wide range of its products.

Security software company Sophos has warned businesses of a security vulnerability affecting a wide range of its products.

The vulnerability relates to the way in which Sophos software handles Microsoft cabinet files (CAB), which are compressed collections of files.

Because the vulnerability can be remotely exploited, the SANS Institute security advisory body said the problem was potentially critical.

The vulnerability can be exploited by crafting a special CAB file with invalid folder count values in the header. This can result in the corruption of heap memory, allowing a hacker to execute arbitrary code on the compromised system.

Sophos said it wasn’t aware of any instances of the flaw being exploited by hackers so far. The company also said it had fixed the vulnerability and updated its customers, so users had no need to take action.

Sophos products affected by the flaw include its desktop anti-virus software and its e-mail gateway security products.
