Integer overflow

Multiple integer overflows in the 1 pppol2tpsendmsg function in net/l2tp/l2tpppp.c, and the 2 l2tpipsendmsg function in net/l2tp/l2tpip.c, in the PPPoL2TP and IPoL2TP implementations in the Linux kernel before 2.6.36.2 allow local users to cause a denial of service heap memory corruption and pani...

Linux Kernel l2tp_ip_sendmsg()和pppol2tp_sendmsg()函数整数溢出漏洞

BUGTRAQ ID: 44762 CVE ID: CVE-2010-4160 Linux Kernel是开放源码操作系统Linux所使用的内核。 Linux Kernel中的PPPoL2TP实现（net/l2tp/l2tpppp.c，pppol2tpsendmsg）和IPoL2TP实现（net /l2tp/l2tpip.c，l2tpipsendmsg）都调用了sockwmalloc，而后者没有执行任何边界检查便对大小参数执行了算术运算。因此，如果发布了超大大小的sendto调用，这个分配大小就会回绕，导致分配过小的缓冲区。成功利用这个漏洞可能导致内核忙碌或内核堆溢出。 Linux...
