Assigned:2009-01-23
Published:2009-01-23
Updated:2018-10-11
Summary:Niels Provos Systrace 1.6f and earlier on the x86_64 Linux platform allows local users to bypass intended access restrictions by making a 32-bit syscall with a syscall number that corresponds to a policy-compliant 64-bit syscall, related to race conditions that occur in monitoring 64-bit processes.
