Dear 190,
Google has identified a new vulnerability in glibc used by most Linux server OS's.
You can read the article on the Google online security blog: https://googleonlinesecurity.blogspot.co.uk/2016/02/cve-2015-7547-glibc-getaddrinfo-stack.html
About the vulnerability:
A stack-based buffer overflow was found in the way the libresolv library performed dual A/AAAA DNS queries. A remote attacker could create a specially crafted DNS response which could cause libresolv to crash or, potentially, execute code with the permissions of the user running the library. Note: this issue is only exposed when libresolv is called from the nss_dns NSS service module. Details of the vulnerability can be found here: CVE-2015-7547
If you are not a QuickHostUK Managed Hosting customer please ensure you have also taken the appropriate actions to secure your own servers. Alternatively, we can handle this for you with our adhoc management scheme, which for this occurrence would be £30 inc VAT per server.
Please contact us if you wish to utilise this service or if you have any questions.
Kind Regards,
