Red Hat Product Errata RHSA-2013:1661 normal SHIPPED_LIVE Moderate: RDMA stack security, bug fix, and enhancement update 2013-11-20 21:53:07 UTC

Description Jan Lieskovsky 2012-10-11 14:49:16 UTC
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.
