Description Agostino Sarubbo gentoo-dev 2012-10-15 08:37:29 UTC 
From oss security:

 A security flaw was found in the way librdmacm, a userspace RDMA Communication
Managment API allowing to specify connections using TCP/IP addresses even though
it opens RDMA specific connections, performed binding to the underlying ib_acm
service (librdmacm used default port value of 6125 to bind to ib_acm service).
An attacker able to run a rogue ib_acm service could use this flaw to make
librdmacm applications to use potentially bogus address resolution information.

CVE-2012-4516 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2012-4516):
  librdmacm 1.0.16, when ibacm.port is not specified, connects to port 6125,
  which allows remote attackers to specify the address resolution information
  for the application via a malicious ib_acm service.
