CVE-2014-4943
CVE-2014-4943 affects the Linux kernel up to 3.15.6, specifically the PPPoL2TP feature in net/l2tp/l2tp_ppp.c. The vulnerability arises from data-structure differences between an l2tp socket and an inet socket, enabling local privilege escalation. Public details in connected sources include PoC/e...

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...
CVE-2010-2495
The pppol2tpxmit function in drivers/net/pppol2tp.c in the L2TP implementation in the Linux kernel before 2.6.34 does not properly validate certain values associated with an interface, which allows attackers to cause a denial of service NULL pointer dereference and OOPS or possibly have unspecifi...

CVE-2008-2750
CVE-2008-2750 affects the Linux kernel (2.6.x) prior to 2.6.26-rc6. The vulnerability is in pppol2tp_recvmsg (drivers/net/pppol2tp.c) and can be triggered by a crafted PPPOL2TP packet that sets an abnormally large length value. Impact per the sources: remote attackers can cause a denial of servic...
