Glibc is widely used .. (including in the kernel code as well) ... perhaps the question is, why wouldn't you update everything?

OK, at the risk of exposing my ignorance, is it sufficient to update glibc (I see that yum-cron has already done this for me), and perhaps to restart some services like named? Or is glibc compiled into packages like BIND and those need to be updated? I'm thinking the glibc libraries are not compiled into the applications but are called at run time, but I really don't know. -----Original Message----- From: Josh Reynolds Sent: Thursday, February 18, 2016 4:53 PM To: [email protected] Subject: Re: [AFMUG] update and patch your linux servers, people! #oldnews Another thing you want to do is limit inbound dns responses to 1024 and less on most platforms, including mikrotik. They may use uClibc though, I am not sure. Most UBNT devices are not vulnerable to this, although EdgeRouter and CloudKey were (and probably that old ubnt nvr appliance). Thankfully they both receive patches from debian upstream, so it's just an apt-get update ; apt-get upgrade -y away.
