CVE-2026-57432 (2026-07-13)

Perl versions through 5.43.10 have an integer overflow in S_measure_struct leading to an out-of-bounds heap read in pack and unpack. S_measure_struct adds each item's size times its repeat count to a running total with no overflow check, so a large repeat count in a pack or unpack template wraps the signed SSize_t total negative. The @, X, and x position codes then guard their moves with a signed length comparison that passes when the length is negative, advancing the buffer pointer out of bounds. A template derived from untrusted input can read heap memory past the buffer and return it to the caller.

CVE-2026-13221 (2026-07-13)

Perl versions through 5.43.9 produce silently incorrect regular expression matches when an alternation of more than 65535 fixed string branches is compiled into a trie in Perl_study_chunk. When such branches are combined into a trie, the delta between the first branch and the shared tail is stored in a 16-bit field. A branch count above 65535 overflows the field, and the trie's match decision table is truncated with no warning or error. A pattern of this shape produces false positive matches (matching strings it should not) and false negative matches (failing to match strings it should). When such a pattern gates an access or filtering decision, the result is wrong.

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.

NAME

Test2::EventFacet::Assert - Facet representing an assertion.

DESCRIPTION

The assertion facet is provided by any event representing an assertion that was made.

FIELDS

$string = $assert->{details}
$string = $assert->details()

Human readable description of the assertion.

$bool = $assert->{pass}
$bool = $assert->pass()

True if the assertion passed.

$bool = $assert->{no_debug}
$bool = $assert->no_debug()

Set this to true if you have provided custom diagnostics and do not want the defaults to be displayed.

$int = $assert->{number}
$int = $assert->number()

(Optional) assertion number. This may be omitted or ignored. This is usually only useful when parsing/processing TAP.

Note: This is not set by the Test2 system, assertion number is not known until AFTER the assertion has been processed. This attribute is part of the spec only for harnesses.
