Description Murray McAllister 2013-10-31 04:55:40 UTC 
Varnish Cache a high-performance HTTP accelerator. A denial of service flaw was found in the way Varnish Cache handled certain GET requests when using certain configurations. A remote attacker could use this flaw to crash a worker process.

Comment 1 Murray McAllister 2013-10-31 04:57:22 UTC 
Created varnish tracking bugs for this issue:

Affects: fedora-all [bug 1025128]
Affects: epel-all [bug 1025129]
Comment 2 Murray McAllister 2013-10-31 04:59:05 UTC 
I was not familiar enough with varnish to reproduce this issue, but the Fedora and EPEL packages are missing the commit from comment #0
Comment 3 Ingvar Hagelund 2013-11-05 11:59:41 UTC 
For Fedora, I'll just wait for 3.0.5, I think. f18 and f19 have 3.0.3. 3.0.4 is commited (but not built) to rawhide.

I have produced a backport to varnish-2.0.6 (epel 5) of this, available here:

I'll try to get upstream to validate it.

If it goes through, I'll do one for epel 6 too.

Comment 4 Ingvar Hagelund 2014-11-26 13:52:00 UTC 
For some reason, this bug is still open.

This was fixed in
varnish-2.0.6-4.el5
varnish-2.1.5-5.el6
varnish-3.0.5-1.fc18
varnish-3.0.5-1.fc19

As all depency bugs were closed long time ago, I close this one as well.
