CVE-2024-56406 (2025-04-13)

A heap buffer overflow vulnerability was discovered in Perl. When there are non-ASCII bytes in the left-hand-side of the `tr` operator, `S_do_trans_invmap` can overflow the destination pointer `d`.    $ perl -e '$_ = "\x{FF}" x 1000000; tr/\xFF/\x{100}/;'    Segmentation fault (core dumped) It is believed that this vulnerability can enable Denial of Service and possibly Code Execution attacks on platforms that lack sufficient defenses.

CVE-2025-40909 (2025-05-30)

Perl threads have a working directory race condition where file operations may target unintended paths. If a directory handle is open at thread creation, the process-wide current working directory is temporarily changed in order to clone that handle for the new thread, which is visible from any third (or more) thread already running. This may lead to unintended operations such as loading code or accessing files from unexpected locations, which a local attacker may be able to exploit. The bug was introduced in commit 11a11ecf4bea72b17d250cfb43c897be1341861e and released in Perl version 5.13.6

NAME

Pod::Text::Termcap - Convert POD data to ASCII text with format escapes

SYNOPSIS

use Pod::Text::Termcap;
my $parser = Pod::Text::Termcap->new (sentence => 0, width => 78);

# Read POD from STDIN and write to STDOUT.
$parser->parse_from_filehandle;

# Read POD from file.pod and write to file.txt.
$parser->parse_from_file ('file.pod', 'file.txt');

DESCRIPTION

Pod::Text::Termcap is a simple subclass of Pod::Text that highlights output text using the correct termcap escape sequences for the current terminal. Apart from the format codes, it in all ways functions like Pod::Text. See Pod::Text for details and available options.

This module uses Term::Cap to find the correct terminal settings. See the documentation of that module for how it finds terminal database information and how to override that behavior if necessary. If unable to find control strings for bold and underscore formatting, that formatting is skipped, resulting in the same output as Pod::Text.

COMPATIBILITY

Pod::Text::Termcap 0.04 (based on Pod::Parser) was the first version of this module included with Perl, in Perl 5.6.0.

The current API based on Pod::Simple was added in Pod::Text::Termcap 2.00. Pod::Text::Termcap 2.01 was included in Perl 5.9.3, the first version of Perl to incorporate those changes.

Several problems with wrapping and line length were fixed as recently as Pod::Text::Termcap 4.11, included in Perl 5.29.1.

Pod::Text::Termcap 4.13 stopped setting the TERMPATH environment variable during module load. It also stopped falling back on VT100 escape sequences if Term::Cap was not able to find usable escape sequences, instead producing unformatted output for better results on dumb terminals. The next version to be incorporated into Perl, 4.14, was included in Perl 5.31.8.

This module inherits its API and most behavior from Pod::Text, so the details in "COMPATIBILITY" in Pod::Text also apply. Pod::Text and Pod::Text::Termcap have had the same module version since 4.00, included in Perl 5.23.7. (They unfortunately diverge in confusing ways prior to that.)
