This vulnerability has been modified since it was last analyzed by the NVD. It is awaiting reanalysis which may result in further changes to the information provided.
The load_elf_binary function in fs/binfmt_elf.c in the Linux kernel before 220.127.116.11 on the x86_64 platform does not ensure that the ELF interpreter is available before a call to the SET_PERSONALITY macro, which allows local users to cause a denial of service (system crash) via a 32-bit application that attempts to execute a 64-bit application and then triggers a segmentation fault, as demonstrated by amd64_killer, related to the flush_old_exec function.
Red Hat is aware of this issue and is tracking it via the following bug:
This issue has been rated as having moderate security impact.
This issue was addressed in Red Hat Enterprise Linux 4 via https://rhn.redhat.com/errata/RHSA-2010-0146.html. Future updates in Red Hat Enterprise Linux 5 and Red Hat Enterprise MRG may address this flaw.
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.
