⭐ Starred 163 / Amon2::Setup::Flavor
Security Advisories (1)
CVE-2025-15604 (2026-03-28)

Amon2 versions before 6.17 for Perl use an insecure random_string implementation for security functions. In versions 6.06 through 6.16, the random_string function will attempt to read bytes from the /dev/urandom device, but if that is unavailable then it generates bytes by concatenating a SHA-1 hash seeded with the built-in rand() function, the PID, and the high resolution epoch time. The PID will come from a small set of numbers, and the epoch time may be guessed, if it is not leaked from the HTTP Date header. The built-in rand function is unsuitable for cryptographic usage. Before version 6.06, there was no fallback when /dev/urandom was not available. Before version 6.04, the random_string function used the built-in rand() function to generate a mixed-case alphanumeric string. This function may be used for generating session ids, generating secrets for signing or encrypting cookie session data and generating tokens used for Cross Site Request Forgery (CSRF) protection.

NAME

Amon2::Setup::Flavor - Abstract base class for flavors.

DESCRIPTION

This is an abstract base class for flavors. But you don't need to inherit this class. Amon2 uses duck typing. You should implement only Class->run method.

In Amon2, flavor means setup script.

METHODS

This class provides some useful methods to write setup script.

$flavor->init()

Hook point to initialize module directory.

$flavor->mkpath($dir)

same as `mkdir -p $dir`.

$flavor->write_file($fnametmpl, $template)

$fnametmpl will be replace with the parameters.

Generate file using Text::Xslate.

For more details, read the source Luke! Or please write docs...

$flavor->write_file_raw($fname, $content)

Write $content to the $fname.
