CVE-2016-3672 (retired)

Priority
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.
Ubuntu-Description
Hector Marco and Ismael Ripoll discovered that the Linux kernel would
improperly disable Address Space Layout Randomization (ASLR) for x86
processes running in 32 bit mode if stack-consumption resource limits were
disabled. A local attacker could use this to make it easier to exploit an
existing vulnerability in a setuid/setgid program.
Notes
jdstrandandroid kernels (flo, goldfish, grouper, maguro, mako and manta) are
not supported on the Ubuntu Touch 14.10 and earlier preview kernels
linux-lts-saucy no longer receives official support
linux-lts-quantal no longer receives official support
