Vulnerability Description
The load_elf_binary function in fs/binfmt_elf.c in the Linux kernel before 2.6.32.8 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.

Linux内核64位Personality处理本地拒绝服务漏洞
Vulnerability Description
Linux kernel是美国Linux基金会发布的开源操作系统Linux所使用的内核。NFSv4 implementation是其中的一个分布式文件系统协议。 Linux Kernel在设置进程的personality时存在错误，本地用户在执行缺少ELF解释器的64位应用时可能触发分段错误，导致内核崩溃。 漏洞起因是fs/binfmt_elf.c文件中的load_elf_binary()函数，该函数在检查ELF解释器可用之前调用了SET_PERSONALITY()，将之前的32位进程转换为了64位进程。
