From: Ulrich =?utf-8?B?U3DDtnJsZWlu?= <u...@freebsd.org> To: freebsd-gnats-sub...@freebsd.org Cc: ead...@freebsd.org Subject: Re: conf/178504: [patch] switch logs compression from bzip2 to xz Date: Wed, 15 May 2013 15:50:09 +0200 This is not only an issue for CPU, but more for RAM. XZ uses a lot more RAM to compress files, and if an attacker can spam logfiles fast enough, especially those that are not rotated on size, like maillog, then they can probably gobble up enough RAM to make it be a problem. I guess the low entropy of logfiles works in our favor here, however.
