Librdmacm is a Library for managing RDMA connections. librdmacm is prone to a security vulnerability because of a design error that causes the library to always connect to default port 6125 if the '/var/run/ibacm.port' file is not found. An attacker may exploit this issue to send malicious address resolution information to the applications using the affected library. This may aid in other attacks. To successfully exploit this issue, an attacker must be able to run a rogue 'ib_acm' service on port 6125 on a server which affected clients may connect to.

An advanced key-value cache and store
A vulnerability in the health check RPM of Cisco IOS XR Software could allow an unauthenticated, remote attacker to access the Redis instance that is running within the NOSi container. This vulnerability exists because the health check RPM opens TCP port 6379 by default upon activation. An attacker could exploit this vulnerability by connecting to the Redis instance on the open port. A successful exploit could allow the attacker to write to the Redis in-memory database, write arbitrary files to the container filesystem, and retrieve information about the Redis database. Given the configuration of the sandboxed container that the Redis instance runs in, a remote attacker would be unable to execute remote code or abuse the integrity of the Cisco IOS XR Software host system.
