CVE-2017-1000371 [HIGH] CVE-2017-1000371: The offset2lib patch as used by the Linux Kernel contains a vulnerability, if RLIMIT_STACK is set to The offset2lib patch as used by the Linux Kernel contains a vulnerability, if RLIMIT_STACK is set to RLIM_INFINITY and 1 Gigabyte of memory is allocated (the maximum under the 1/4 restriction) then the stack will be grown down to 0x80000000, and as the PIE binary is mapped above 0x80000000 the minimum distance between the end of the PIE binary's read-writ

CVE-2017-1000370 [HIGH] CVE-2017-1000370: The offset2lib patch as used in the Linux Kernel contains a vulnerability that allows a PIE binary t 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 offset2lib patch. This affects Linux Kernel version 4.11.5 and earl
