"Cyku Hong from DEVCORE discovered that php-nette, a PHP MVC framework,
is vulnerable to a code injection attack by passing specially formed
parameters to URL that may possibly leading to remote code execution.

For Debian 9 stretch, this problem has been fixed in version
2.4-20160731-1+deb9u1.

We recommend that you upgrade your php-nette packages.

For the detailed security status of php-nette please refer to its
security tracker page at:
https://security-tracker.debian.org/tracker/php-nette

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
