Scientific Linux Security Update : RDMA stack on SL6.x i386/x86_64
Medium Nessus Plugin ID 71294
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionA flaw was found in the way ibutils handled temporary files. A local attacker could use this flaw to cause arbitrary files to be overwritten as the root user via a symbolic link attack.
It was discovered that librdmacm used a static port to connect to the ib_acm service. A local attacker able to run a specially crafted ib_acm service on that port could use this flaw to provide incorrect address resolution information to librmdacm applications.
This advisory updates the following packages to the latest upstream releases, providing a number of bug fixes and enhancements over the previous versions :
Several bugs have been fixed in the openmpi, mpitests, ibutils, and infinipath-psm packages.
The most notable changes in these updated packages from the RDMA stack are the following :
- Multiple bugs in the Message Passing Interface (MPI) test packages were resolved, allowing more of the mpitest applications to pass on the underlying MPI implementations.
- The libmlx4 package now includes dracut module files to ensure that any necessary custom configuration of mlx4 port types is included in the initramfs dracut builds.
- Multiple test programs in the perftest and qperf packages now work properly over RoCE interfaces, or when specifying the use of rdmacm queue pairs.
- The mstflint package has been updated to the latest upstream version, which is now capable of burning firmware on newly released Mellanox Connect-IB hardware.
- A compatibility problem between the openmpi and infinipath-psm packages has been resolved with new builds of these packages.
SolutionUpdate the affected packages.
