Amazon Linux AMI Security Advisory: ALAS-2016-757
Advisory Release Date: 2016-10-20 04:11 Pacific
Advisory Updated Date: 2016-11-10 18:00 Pacific
Severity:
Critical
References:
CVE-2016-5195
Issue Overview:
A race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write (COW) breakage of private read-only memory mappings. An unprivileged local user could use this flaw to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system.
(Updated 2016-11-10: This advisory was upgraded to Critical.)
Affected Packages:
kernel
Issue Correction:
