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

CVE-2023-47100

In Perl before 5.38.2, S_parse_uniprop_string in regcomp.c can write to unallocated space because a property name associated with a \p{...} regular expression construct is mishandled. The earliest affected version is 5.30.0.

CVE-2020-12723 (2020-06-05)

regcomp.c in Perl before 5.30.3 allows a buffer overflow via a crafted regular expression because of recursive S_study_chunk calls.

CVE-2020-10543 (2020-06-05)

Perl before 5.30.3 on 32-bit platforms allows a heap-based buffer overflow because nested regular expression quantifiers have an integer overflow.

CVE-2023-47039 (2023-10-30)

Perl for Windows relies on the system path environment variable to find the shell (cmd.exe). When running an executable which uses Windows Perl interpreter, Perl attempts to find and execute cmd.exe within the operating system. However, due to path search order issues, Perl initially looks for cmd.exe in the current working directory. An attacker with limited privileges can exploit this behavior by placing cmd.exe in locations with weak permissions, such as C:\ProgramData. By doing so, when an administrator attempts to use this executable from these compromised locations, arbitrary code can be executed.

CVE-2020-10878 (2020-06-05)

Perl before 5.30.3 has an integer overflow related to mishandling of a "PL_regkind[OP(n)] == NOTHING" situation. A crafted regular expression could lead to malformed bytecode with a possibility of instruction injection.

CVE-2018-6798 (2018-04-17)

An issue was discovered in Perl 5.22 through 5.26. Matching a crafted locale dependent regular expression can cause a heap-based buffer over-read and potentially information disclosure.

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.

ENVIRONMENT

This module sets the TERMPATH environment variable globally to:

$HOME/.termcap:/etc/termcap:/usr/share/misc/termcap:/usr/share/lib/termcap

if it isn't already set. (The first entry is omitted if the HOME environment variable isn't set.) This is a (very old) workaround for problems finding termcap information on older versions of Solaris, and is not good module behavior. Please do not rely on this behavior; it may be dropped in a future release.

NOTES

This module uses Term::Cap to retrieve the formatting escape sequences for the current terminal, and falls back on the ECMA-48 (the same in this regard as ANSI X3.64 and ISO 6429, the escape codes also used by DEC VT100 terminals) if the bold, underline, and reset codes aren't set in the termcap information.

Pod::Text, Pod::Simple, Term::Cap

The current version of this module is always available from its web site at http://www.eyrie.org/~eagle/software/podlators/. It is also part of the Perl core distribution as of 5.6.0.
