| CVE-2026-4176 | Cri | 0.57 | 9.8 | 0.00 | | Mar 29, 2026 | 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. |

| CVE-2011-1487 | | 0.03 | — | 0.04 | | Apr 11, 2011 | The (1) lc, (2) lcfirst, (3) uc, and (4) ucfirst functions in Perl 5.10.x, 5.11.x, and 5.12.x through 5.12.3, and 5.13.x through 5.13.11, do not apply the taint attribute to the return value upon processing tainted input, which might allow context-dependent attackers to bypass the taint protection mechanism via a crafted string. |
| CVE-2008-2827 | | 0.03 | — | 0.00 | | Jun 23, 2008 | The rmtree function in lib/File/Path.pm in Perl 5.10 does not properly check permissions before performing a chmod, which allows local users to modify the permissions of arbitrary files via a symlink attack, a different vulnerability than CVE-2005-0448 and CVE-2004-0452. |
| CVE-2011-2939 | | 0.01 | — | 0.07 | | Jan 13, 2012 | Off-by-one error in the decode_xs function in Unicode/Unicode.xs in the Encode module before 2.44, as used in Perl before 5.15.6, might allow context-dependent attackers to cause a denial of service (memory corruption) via a crafted Unicode string, which triggers a heap-based buffer overflow. |
| CVE-2024-56406 | | 0.00 | — | 0.00 | | Apr 13, 2025 | A heap buffer overflow vulnerability was discovered in Perl.
Release branches 5.34, 5.36, 5.38 and 5.40 are affected, including development versions from 5.33.1 through 5.41.10.
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-2013-7422 | | 0.00 | — | 0.01 | | Aug 16, 2015 | Integer underflow in regcomp.c in Perl before 5.20, as used in Apple OS X before 10.10.5 and other products, allows context-dependent attackers to execute arbitrary code or cause a denial of service (application crash) via a long digit string associated with an invalid backreference within a regular expression. |

| CVE-2012-1151 | | 0.00 | — | 0.02 | | Sep 9, 2012 | Multiple format string vulnerabilities in dbdimp.c in DBD::Pg (aka DBD-Pg or libdbd-pg-perl) module before 2.19.0 for Perl allow remote PostgreSQL database servers to cause a denial of service (process crash) via format string specifiers in (1) a crafted database warning to the pg_warn function or (2) a crafted DBD statement to the dbd_st_prepare function. |
| CVE-2010-1158 | | 0.00 | — | 0.01 | | Apr 20, 2010 | Integer overflow in the regular expression engine in Perl 5.8.x allows context-dependent attackers to cause a denial of service (stack consumption and application crash) by matching a crafted regular expression against a long string. |
