CVE-2009-0835

Summary (CVE-2009-0835) in the Linux kernel (2.6.28.7 and earlier on x86_64) describes a local privilege issue within the seccomp filter. The __secure_computing function does not correctly handle calls where a 32‑bit process makes a 64‑bit syscall or a 64‑bit process makes a 32‑bit syscall, allow...

Linux Kernel seccomp系统调用绕过安全限制漏洞

BUGTRAQ ID: 33948 Linux Kernel是开放源码操作系统Linux所使用的内核。 Linux Kernel内嵌有被称为seccomp的系统调用过滤技术，允许进程将其本身严格的限制到受限的系统调用集，如read、write、exit、sigreturn等。PRSETSECCOMP功能的实现中存在错误，允许本地用户通过将32位进程切换到64位模式并在64位进程中使用syscall指令或interrupt 80h绕过安全执行某些受限制的系统调用。 Linux kernel 2.6.x 厂商补丁： Linux -----...
