CVE-2026-8376 (2026-05-25)

Perl versions through 5.43.10 have a heap buffer overflow when compiling regular expressions with a repeated fixed string on 32-bit builds. Perl_study_chunk in regcomp_study.c checked the size of the joined substring buffer in characters rather than bytes. For a quantified fixed substring with a large minimum count, the byte length mincount * l could overflow SSize_t, producing an undersized SvGROW allocation; the subsequent copy writes past the end of the buffer. A caller that compiles an attacker-controlled regular expression on a 32-bit perl build triggers a heap buffer overflow at compile time.

CVE-2026-4176 (2026-03-29)

Perl versions from 5.9.4 before 5.40.4-RC1, from 5.41.0 before 5.42.2-RC1, from 5.43.0 before 5.43.9 contain a vulnerable version of Compress::Raw::Zlib. Compress::Raw::Zlib is included in the Perl package as a dual-life core module, and is vulnerable to CVE-2026-3381 due to a vendored version of zlib which has several vulnerabilities, including CVE-2026-27171. The bundled Compress::Raw::Zlib was updated to version 2.221 in Perl blead commit c75ae9cc164205e1b6d6dbd57bd2c65c8593fe94.

NAME

Test2::EventFacet::Render - Facet that dictates how to render an event.

DESCRIPTION

This facet is used to dictate how the event should be rendered by the standard test2 rendering tools. If this facet is present then ONLY what is specified by it will be rendered. It is assumed that anything important or note-worthy will be present here, no other facets will be considered for rendering/display.

This facet is a list type, you can add as many items as needed.

FIELDS

$string = $render->[#]->{details}
$string = $render->[#]->details()

Human readable text for display.

$string = $render->[#]->{tag}
$string = $render->[#]->tag()

Tag that should prefix/identify the main text.

$string = $render->[#]->{facet}
$string = $render->[#]->facet()

Optional, if the display text was generated from another facet this should state what facet it was.

$mode = $render->[#]->{mode}
$mode = $render->[#]->mode()
calculated

Calculated means the facet was generated from another facet. Calculated facets may be cleared and regenerated whenever the event state changes.

replace

Replace means the facet is intended to replace the normal rendering of the event.
