CentOS 7 is derived from the freely distributed source code of the commercial Red Hat Enterprise Linux 7 operating system series, which means that it also benefits of its security patches. According to the recently published RHSA-2017:0086-1 security advisory, which was marked as important, three security vulnerabilities are patched. Two of these security flaws are marked as moderate and one as important. Documented as CVE-2016-7117, the latter is a use-after-free vulnerability discovered in Linux kernel’s socket recvmmsg subsystem, which could allow a remote attacker to execute malicious code and corrupt memory.
