kernel: Incorrectly mapped contents of PIE executable

The Linux Kernel running on AMD64 systems will sometimes map the contents of PIE executable, the heap or ld.so to where the stack is mapped allowing attackers to more easily manipulate the stack. Linux Kernel version 4.11.5 is affected...

UBUNTU-CVE-2017-1000370

The offset2lib patch as used in the Linux Kernel contains a vulnerability that allows a PIE binary to be execve'ed with 1GB of arguments or environmental strings then the stack occupies the address 0x80000000 and the PIE binary is mapped above 0x40000000 nullifying the protection of the offset2li...
