Linux Kernel审计系统audit_syscall_entry()系统调用绕过安全限制漏洞

BUGTRAQ ID: 33951 Linux Kernel是开放源码操作系统Linux所使用的内核。 Syscall过滤技术通常基于由编号确定的syscall或具体参数来确认是否允许执行调用。在通过编号确定syscall时，64位Linux内核（x8664）上syscall编号可能既映射到32位又映射到64位的syscall表，而这两种syscall表是不同的。由于用户空间进程是由 syscall表控制的，因此可以绕过syscall编号检查，执行非授权操作。 例如，syscall过滤技术可能在监控64位进程，且配置为允许常见的open syscall的子集，在64位平台上为syscal...
