CVE-2016-1238 (2016-08-02)

Imager would search the default current directory entry in @INC when searching for file format support modules.

CVE-2007-2459 (2007-05-02)

Heap-based buffer overflow in the BMP reader (bmp.c) in Imager perl module (libimager-perl) 0.45 through 0.56 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via crafted 8-bit/pixel compressed BMP files.

CPANSA-Imager-2014-01 (2014-01-03)

When drawing on an image with an alpha channel where the source minimum is greater than zero, Imager would read from beyond the end of a malloc() allocated buffer. In rare circumstances this could lead to some of the source image not being written to the target image, or possibly to a segmentation fault.

CVE-2024-53901 (2024-11-17)

"invalid next size" backtrace on use of trim on certain images

CVE-2006-0053 (2006-04-10)

Imager (libimager-perl) before 0.50 allows user-assisted attackers to cause a denial of service (segmentation fault) by writing a 2- or 4-channel JPEG image (or a 2-channel TGA image) to a scalar, which triggers a NULL pointer dereference.

CVE-2026-8669 (2026-05-15)

Imager versions through 1.030 for Perl allow a heap out of bounds (OOB) write on crafted multi-frame GIF files. Imager::File::GIF's i_readgif_multi_low allocates a single per-row buffer GifRow sized for the GIF's global screen width 'SWidth' and reuses it across every image in the file. The page-match branch validates Image.Width + Image.Left > SWidth before each DGifGetLine write, but the parallel skip-image branch at imgif.c:790-805 calls DGifGetLine(GifFile, GifRow, Width) with no such check.

NAME

Imager::Regops - generated information about the register based VM

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.
