Privilege escalation vulnerability in Kernel via MAP_PRIVATE COW breakage
|ID: oval:org.secpod.oval:def:37804||Date: (C)2016-10-24 (M)2019-03-17|
|Class: VULNERABILITY||Family: unix|
The host installed with kernel package on CentOS 5, 6 or 7 and is prone to a privilege escalation vulnerability. A flaw is present in the application, which fails to properly handle the copy-on-write (COW) breakage of private read-only memory mappings. Successful exploitation could allow attackers to gain write access to otherwise read-only memory mappings and thus increase their privileges on the system.
