CVE-2025-30673 (2025-04-01)

Sub::HandlesVia for Perl before 0.050002 allows untrusted code from the current working directory ('.') to be loaded similar to CVE-2016-1238. If an attacker can place a malicious file in current working directory, it may be loaded instead of the intended file, potentially leading to arbitrary code execution. Sub::HandlesVia uses Mite to produce the affected code section due to CVE-2025-30672

NAME

Sub::HandlesVia::HandlerLibrary::Number - library of number-related methods

SYNOPSIS

package My::Class {
  use Moo;
  use Sub::HandlesVia;
  use Types::Standard 'Num';
  has attr => (
    is => 'rwp',
    isa => Num,
    handles_via => 'Number',
    handles => {
      'my_abs' => 'abs',
      'my_add' => 'add',
      'my_cmp' => 'cmp',
      'my_div' => 'div',
      'my_eq' => 'eq',
      'my_ge' => 'ge',
      'my_get' => 'get',
      'my_gt' => 'gt',
      'my_le' => 'le',
      'my_lt' => 'lt',
      'my_mod' => 'mod',
      'my_mul' => 'mul',
      'my_ne' => 'ne',
      'my_set' => 'set',
      'my_sub' => 'sub',
    },
  );
}

DESCRIPTION

This is a library of methods for Sub::HandlesVia.

DELEGATABLE METHODS

abs()

Finds the absolute value of the current number, updating the attribute.

my $object = My::Class->new( attr => -5 );
$object->my_abs;
say $object->attr; ## ==> 5

add( $addend )

Arguments: Num.

Adds a number to the existing number, updating the attribute.

my $object = My::Class->new( attr => 4 );
$object->my_add( 5 );
say $object->attr; ## ==> 9

cmp( $num )

Arguments: Num.

Returns $object->attr <=> $num.

div( $divisor )

Arguments: Num.

Divides the existing number by a number, updating the attribute.

my $object = My::Class->new( attr => 6 );
$object->my_div( 2 );
say $object->attr; ## ==> 3

eq( $num )

Arguments: Num.

Returns $object->attr == $num.

ge( $num )

Arguments: Num.

Returns $object->attr >= $num.

get()

Returns the current value of the number.

my $object = My::Class->new( attr => 4 );
say $object->my_get; ## ==> 4

gt( $num )

Arguments: Num.

Returns $object->attr > $num.

le( $num )

Arguments: Num.

Returns $object->attr <= $num.

lt( $num )

Arguments: Num.

Returns $object->attr < $num.

mod( $divisor )

Arguments: Num.

Finds the current number modulo a divisor, updating the attribute.

my $object = My::Class->new( attr => 5 );
$object->my_mod( 2 );
say $object->attr; ## ==> 1

mul( $factor )

Arguments: Num.

Multiplies the existing number by a number, updating the attribute.

my $object = My::Class->new( attr => 2 );
$object->my_mul( 5 );
say $object->attr; ## ==> 10

ne( $num )

Arguments: Num.

Returns $object->attr != $num.

set( $value )

Arguments: Num.

Sets the number to a new value.

my $object = My::Class->new( attr => 4 );
$object->my_set( 5 );
say $object->attr; ## ==> 5

sub( $subtrahend )

Arguments: Num.

Subtracts a number from the existing number, updating the attribute.

my $object = My::Class->new( attr => 9 );
$object->my_sub( 6 );
say $object->attr; ## ==> 3
