Imager-1.032
⭐ Starred 27 / Imager::Font::FreeType2
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::Font::FreeType2 - low-level functions for FreeType2 text output

DESCRIPTION

Imager::Font creates a Imager::Font::FreeType2 object when asked to.

See Imager::Font to see how to use this type.

This class provides low-level functions that require the caller to perform data validation.

This driver supports:

transform()
dpi()
draw()

The following parameters:

  • utf8

  • vlayout

  • sizew

Special behaviors

If you call transform() to set a transformation matrix, hinting will be switched off. This prevents sudden jumps in the size of the text caused by the hinting when the transformation is the identity matrix. If for some reason you want hinting enabled, use $font->hinting(hinting=>1) to re-enable hinting. This will need to be called after each call to transform().
