Descriptions

The __secure_computing function in kernel/seccomp.c in the seccomp subsystem in the Linux kernel 2.6.28.7 and earlier on the x86_64 platform, when CONFIG_SECCOMP is enabled, does not properly handle (1) a 32-bit process making a 64-bit syscall or (2) a 64-bit process making a 32-bit syscall, which allows local users to bypass intended access restrictions via crafted syscalls that are misinterpreted as (a) stat or (b) chmod, a related issue to CVE-2009-0342 and CVE-2009-0343.

La función __secure_computing en kernel/seccomp.c en el subsistema seccomp en el núcleo de Linux v2.6.28.7 y versiones anteriores en la plataforma x86_64, cuando CONFIG_SECCOMP está activo, no maneja adecuadamente (1) un proceso de 32-bit haciendo una llamada al sistema (syscall) de 64-bit o (2) un proceso de 64-bit haciendo una llamada al sistema (syscall) de 32-bit, lo cual permite a usuarios locales evitar restricciones de acceso a través de llamadas al sistema (syscalls) manipuladsa que son malinterpretadas como (a) stat o (b) chmod, una cuestión distinta que CVE-2009-0342 y CVE-2009-0343.
