Linux Kernel gdth实现内核内存破坏漏洞

CVE ID: CVE-2010-4157 Linux Kernel是开放源码操作系统Linux所使用的内核。 Linux Kernel的gdthioctlalloc函数取值大小变量为int型，而copyfromuser函数取大小变量为无符长型。 gen.datalen和gen.senselen为无符长型，在x8664系统上长型为64位，int型为32位。如果用户传送了超长值的话，分配就会将大小截短为32位，分配过小的缓冲区，之后在执行copyfromuser时可能导致内存破坏。 Linux kernel 2.6.x 厂商补丁： Linux -----...
