Security Advisory Description CVE-2017-1000370 The offset2lib patch as used in the Linux Kernel contains a vulnerability that allows a PIE binary to be execveed with 1GB of arguments or environmental strings then the stack occupies the address 0x80000000 and the PIE binary is mapped above...

CVE-2017-1000371

A flaw was found in the Linux kernel's implementation of mapping ELF PIE binary loading to allow evasion of the stack-guard page protection mechanisms that intend to mitigate this behavior. This issue appears to be limited to i386 based systems...

CVE-2017-1000371

The offset2lib patch as used by the Linux Kernel contains a vulnerability, if RLIMITSTACK is set to RLIMINFINITY 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 minimu...
