QNAP Systems Inc. announced firmware updates for Turbo NAS systems with vulnerability to the OpenSSL Heartbleed bug (CVE-2014-0160). The operating systems vulnerable to Heartbleed are QTS versions 4.0 and 4.1. Versions 3.8 and earlier use a different version of OpenSSL and are not affected by the OpenSSL Heartbleed bug.
As described on the Common Vulnerabilities and Exposures website, some versions of the OpenSSL TLS and DTLS implementation do not properly process Heartbeat Extension packets which allow remote attackers to obtain sensitive information by reading private keys (aka the Heartbleed bug).
“We strongly urge users of vulnerable Turbo NAS systems to update their firmware,” said Jason Hsu, Product Manager of QNAP. “Users are also recommended to contact their SSL providers to regenerate their SSL CSR/keys for server protection.”
