Pound, a reverse proxy, load balancer and HTTPS front-end for Web servers, is found to have the TLS compression enabled, which makes possible a practical attack CRIME, and there is no option to disable the TLS compression. Some explanations and a possible patch is given here: https://community.qualys.com/blogs/securitylabs/2012/09/14/crime-information-leakage-attack-against-ssltls References: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=727197 Commit: https://github.com/goochjj/pound/commit/a0c52c542ca9620a96750f9877b26bf4c84aef1b
Created Pound tracking bugs for this issue: Affects: fedora-all [bug 1030843] Affects: epel-all [bug 1030844]
This should not be an issue in Fedora or EPEL any more. OpenSSL packages in Fedora and Red Hat Enterprise Linux 5 and 6 used to default to having compression enabled by default, but that was changed and compression it not enabled by default any more: http://pkgs.fedoraproject.org/cgit/openssl.git/commit/?id=169c3a0 https://rhn.redhat.com/errata/RHSA-2013-0587.html There is an option to enable compression by setting OPENSSL_DEFAULT_ZLIB environment variable. If using older openssl packages, compression can be disabled using OPENSSL_NO_DEFAULT_ZLIB environment variable - see bug 857051 comment 5 for further details.
