Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that composer, a dependency manager for PHP, did not properly sanitize Mercurial URLs, which could lead to arbitrary code execution.

For Debian 9 stretch, this problem has been fixed in version 1.2.2-1+deb9u1.

We recommend that you upgrade your composer packages.

For the detailed security status of composer please refer to its security tracker page at:
