Security Advisories (1)
CVE-2026-5085 (2026-04-13)

Solstice::Session versions through 1440 for Perl generates session ids insecurely. The _generateSessionID method returns an MD5 digest seeded by the epoch time, a random hash reference, a call to the built-in rand() function and the process id. The same method is used in the _generateID method in Solstice::Subsession, which is part of the same distribution. The epoch time may be guessed, if it is not leaked in the HTTP Date header. Stringified hash refences will contain predictable content. The built-in rand() function is seeded by 16-bits and is unsuitable for security purposes. The process id comes from a small set of numbers. Predictable session ids could allow an attacker to gain access to systems.

NAME

Solstice::Model::List - Superclass for classes that need to be both a List and a Model.

SYNOPSIS

use Solstice::Model::List;; 

my $model = Solstice::Model::List->new();

DESCRIPTION

Export

None by default.

Methods

new ()

Creates and returns an empty Solstice::Model::List object.

clear()

Removes all entries from the List object.

reverse()

Reverse the order of the entries in the List.

push($element)

Adds an element to the end of the List.

pop()

Remove the last element in the List and return it.

unshift($element)

Adds an element to the front of the List.

shift()

Remove the first element in the List and return it.

add ([$index,] $element)

Adds an element to the List. If no index is given it will be added to the end of the List, otherwise it will be placed at the index given, and the other elements will be shifted out of the way. Passing $index equal to the list size is also permissible. It is 0 indexed.

addList($list)
replace($index, $element)

Replace an element in the List. It is 0 indexed. If successful, the replaced element is returned.

move ($oldindex, $newindex)

This will move an element from one position in the List to another. It is 0 indexed. Note: This will not reset any iterators, so there may be some confusion if you iterate over a List you are still manipulating.

onMove
remove ($index)

This will remove an element from the List, at the index given. It is 0 indexed. If successful, the removed element is returned.

onRemove

This is an empty method meant for overriding by subclasses

Private Methods

_clear()
_add([$position,] $element)
_addList($list)
_listChanged()
