CVE-2014-3619 glusterfs: fragment header infinite loop DoS
Last modified: 2016-03-04 07:21:50 EST
IssueDescription: A denial of service flaw was found in the way the __socket_proto_state_machine() function of glusterfs processed certain fragment headers. A remote attacker could send a specially crafted fragment header that, when processed, would cause the glusterfs process to enter an infinite loop.

I'm interested in checking the status if glusterfs in Debian is affected as well. The original report seems to be restricted, is there information/patches/affected versions which you are can share about the issue? Many thanks in advance for any pointer, Regards, Salvatore

Upstream patch that, among other things, fixes this issue: http://review.gluster.org/#/c/8662/4 The infinite loop could be triggered if a fragment header of '00000000' was sent, causing the code in __socket_proto_state_machine() to loop indefinitely.
