HIGH
Linux Kernel (x86) - Disable ASLR by Setting the RLIMIT_STACK Resource to Unlimited
Record summary
CVE-2016-3672 has a selected CVSS score of 7.8 (high); EIP currently links 1 catalogued exploit.
Description
The arch_pick_mmap_layout function in arch/x86/mm/mmap.c in the Linux kernel through 4.5.2 does not properly randomize the legacy base address, which makes it easier for local users to defeat the intended restrictions on the ADDR_NO_RANDOMIZE flag, and bypass the ASLR protection mechanism for a setuid or setgid program, by disabling stack-consumption resource limits.
