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

IntegerLibrary - A library of generic integer manipulation functions.

SYNOPSIS

use IntegerLibrary qw(inttoroman);

my $str = inttoroman(49);

DESCRIPTION

Functions in this library make no assumptions about the integer being modified.

Superclass

Functions

inttobytes($int, $compact)

Returns $int transformed into a string displaying a byte size; $compact specifies an abbreviated units label.

inttotime($int, $compact)

Returns $int transformed into a string displaying hours, minutes, seconds; $compact specifies a HH:MM:SS format.

inttoword($int)

Returns $int transformed into a string containing its equivalent word form. Currently, 1-9 are implemented. If greater number conversions are required, consider reimplementing this function as a wrapper around Lingua::EN::Nums2Words.

inttoroman($int, $upper)

Returns $int transformed into a roman numeral string; $int must be a non-zero integer between -4000 and 4000. $upper specifies upper-case.

inttolatin($int, $upper)

Returns $int transformed into a latin alphabet string, where $int is a non-zero integer. $upper specifies upper-case.

Private Functions

_inttoroman($int)

Internal function for converting $int to a roman numeral string

_inttolatin($int)

Recursive function for converting $int to a latin alphabet string

Modules Used

Exporter.
