Synopsis

The remote Debian host is missing a security update.

Description

An issue has been found in libbsd, a library with utility functions from BSD systems. A non-NUL terminated symbol name in the string table might result in an out-of-bounds read.

For Debian 9 stretch, this problem has been fixed in version 0.8.3-1+deb9u1.

We recommend that you upgrade your libbsd packages.
