  "details" : [ "Integer overflow in the rds_rdma_pages function in net/rds/rdma.c in the Linux kernel allows local users to cause a denial of service (crash) and possibly execute arbitrary code via a crafted iovec struct in a Reliable Datagram Sockets (RDS) request, which triggers a buffer overflow." ],
  "statement" : "The Linux kernel as shipped with Red Hat Enterprise Linux 3, 4 and Red Hat\nEnterprise MRG did not include support for the RDS Protocol, and therefore are\nnot affected by this issue. Future kernel updates in Red Hat Enterprise Linux 5\nmay address this flaw.",

  "mitigation" : {
    "value" : "For users that do not run applications that use RDS, you can prevent the rds\nmodule from being loaded by adding the following entry to the end of the\n/etc/modprobe.d/blacklist file:\nblacklist rds\nThis way, the rds module cannot be loaded accidentally, which may occur if an\napplication that requires RDS is started. A reboot is not necessary for this\nchange to take effect but do make sure the module is not loaded in the first\nplace. You can verify that by running:\nlsmod | grep rds\nYou may also consider removing the CAP_SYS_MODULE capability from the current\nglobal capability set to prevent kernel modules from being loaded or unloaded.\nThe CAP_SYS_MODULE has a capability number of 16 (see linux/capability.h). The\ndefault value has all the bits set. To remove this capability, you have to\nclear the 16th bit of the default 32-bit value, e.g. 0xffffff ^ (1 << 16):\necho 0xFFFEFFFF > /proc/sys/kernel/cap-bound",
