Linux Kernel nfs_lock函数本地拒绝服务漏洞

CVECAN ID: CVE-2007-6733 Linux Kernel是开放源码操作系统Linux所使用的内核。 Linux Kernel的fs/nfs/file.c文件中的nfslock函数没有正确的删除对setgid未设置group-execute权限文件的 POSIX锁定，这允许本地用户通过在NSF文件系统上锁定文件然后再更改该文件的权限导致系统崩溃。 Linux kernel 2.6.9 厂商补丁： Linux ----- 目前厂商已经发布了升级补丁以修复这个安全问题，请到厂商的主页下载： http://lkml.org/lkml/2005/12/21/334...

CVE-2007-6733: Undefined Security Weakness

The nfslock function in fs/nfs/file.c in the Linux kernel 2.6.9 does not properly remove POSIX locks on files that are setgid without group-execute permission, which allows local users to cause a denial of service BUG and system crash by locking a file on an NFS filesystem and then changing this...

CVE-2010-0307

The loadelfbinary function in fs/binfmtelf.c in the Linux kernel before 2.6.32.8 on the x8664 platform does not ensure that the ELF interpreter is available before a call to the SETPERSONALITY macro, which allows local users to cause a denial of service system crash via a 32-bit application that...

Linux Kernel 64位Personality处理本地拒绝服务漏洞

BUGTRAQ ID: 38027 Linux Kernel是开放源码操作系统Linux所使用的内核。 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/binfmtelf.c文件中的loadelfbinary函数，该函数在检查ELF解释器可用之前调用了 SETPERSONALITY，将之前的32位进程转换为了64位进程。如果execve成功，这不会导致问题，但在...
