Major security flaw threatens Linux users

March 5, 2014 – 4:25 AM

A source code mistake in the GnuTLS library an open-source software building block used in a large number of different Linux distributions to handle secure Internet connections could prove a serious threat to the privacy of Linux users, as developers rush to patch the vulnerability.

Nikos Mavrogiannopolous, the developer of GnuTLS, announced Monday in a mailing list¬†message¬†that he had implemented a fix to the source code that closes the loophole. The flaw would have enabled an attacker to spoof GnuTLS’ system for verifying certificates, exposing supposedly secure connections to stealthy eavesdropping.

By creating a specific type of fake certificate, an attacker could trick GnuTLS into accepting it as genuine, granting access to an otherwise-secure connection. This done, the intruder could monitor traffic flowing through the connection in plain text, and even interject code of his own, potentially opening further avenues of attack.
