  "details" : [ "The do_sigaltstack function in kernel/signal.c in Linux kernel 2.4 through 2.4.37 and 2.6 before 2.6.31-rc5, when running on 64-bit systems, does not clear certain padding bytes from a structure, which allows local users to obtain sensitive information from the kernel stack via the sigaltstack function." ],
  "statement" : "This issue is not planned to be fixed in Red Hat Enterprise Linux 3, due to this product being in Production 3 of its maintenance life-cycle, where only qualified security errata of important or critical impact are addressed.
