What is CVE-2017-1000376?

CVE-2017-1000376 is a high-severity memory corruption vulnerability in Debian Debian Linux, published on 19 Jun 2017. It can only be exploited from the same machine or local network, with no action from the victim.

Official description

libffi requests an executable stack allowing attackers to more easily trigger arbitrary code execution by overwriting the stack. Please note that libffi is used by a number of other libraries. It was previously stated that this affects libffi version 3.2.1 but this appears to be incorrect. libffi prior to version 3.1 on 32 bit x86 systems was vulnerable, and upstream is believed to have fixed this issue in version 3.1.

Weakness: CWE-119
