Imager-1.032
⭐ Starred 27 / Imager::Regops
Security Advisories (1)
CVE-2026-14454 (2026-07-08)

Imager versions before 1.033 for Perl treat unsigned EXIF IFD entry counts as signed. Imager mishandled large EXIF IFD entry count values, treating them as negative numbers. This could lead to an attempt to allocate a block nearly the size of the address space, which fails and kills the process. An attacker could craft an image with EXIF data that terminates a worker process.

NAME

Imager::Regops - generated information about the register based virtual machine

SYNOPSIS

use Imager::Regops;
$Imager::Regops::Attr{$opname}->{opcode} # opcode for given operator
$Imager::Regops::Attr{$opname}->{parms} # number of parameters
$Imager::Regops::Attr{$opname}->{types} # types of parameters
$Imager::Regops::Attr{$opname}->{func} # operator is a function
$Imager::Regops::Attr{$opname}->{result} # r for numeric, p for pixel result
$Imager::Regops::MaxOperands; # maximum number of operands

DESCRIPTION

This module is generated automatically from regmach.h so we don't need to maintain the same information in at least one extra place.

At least that's the idea.
