CVE-2023-47039 2 Microsoft, Perl 2 Windows, Perl 2024-01-08 N/A 7.8 HIGH
A vulnerability was found in Perl. This security issue occurs while Perl for Windows relies on the system path environment variable to find the shell (`cmd.exe`). When running an executable that uses the 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. This flaw allows an attacker with limited privileges to place`cmd.exe` in locations with weak permissions, such as `C:\ProgramData`. By doing so, arbitrary code can be executed when an administrator attempts to use this executable from these compromised locations.
CVE-2023-47038 2 Perl, Redhat 2 Perl, Enterprise Linux 2023-12-29 N/A 7.8 HIGH
A vulnerability was found in perl. This issue occurs when a crafted regular expression is compiled by perl, which can allow an attacker controlled byte buffer overflow in a heap allocated buffer.
CVE-2023-31484 2 Cpanpm Project, Perl 2 Cpanpm, Perl 2023-08-02 N/A 8.1 HIGH
CPAN.pm before 2.35 does not verify TLS certificates when downloading distributions over HTTPS.
CVE-2020-10878 5 Fedoraproject, Netapp, Opensuse and 2 more 17 Fedora, Oncommand Workflow Automation, Snap Creator Framework and 14 more 2022-05-12 7.5 HIGH 8.6 HIGH
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-2020-10543 4 Fedoraproject, Opensuse, Oracle and 1 more 15 Fedora, Leap, Communications Billing And Revenue Management and 12 more 2022-05-12 6.4 MEDIUM 8.2 HIGH
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-2020-12723 5 Fedoraproject, Netapp, Opensuse and 2 more 16 Fedora, Oncommand Workflow Automation, Snap Creator Framework and 13 more 2022-05-12 5.0 MEDIUM 7.5 HIGH
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-2021-36770 3 Fedoraproject, P5-encode Project, Perl 3 Fedora, P5-encode, Perl 2022-05-03 6.8 MEDIUM 7.8 HIGH
Encode.pm, as distributed in Perl through 5.34.0, allows local users to gain privileges via a Trojan horse Encode::ConfigLocal library (in the current working directory) that preempts dynamic module loading. Exploitation requires an unusual configuration, and certain 2021 versions of Encode.pm (3.05 through 3.11). This issue occurs because the || operator evaluates @INC in a scalar context, and thus @INC has only an integer value.
CVE-2020-16156 1 Perl 1 Comprehensive Perl Archive Network 2022-01-12 6.8 MEDIUM 7.8 HIGH
CPAN 2.28 allows Signature Verification Bypass.
CVE-2016-6185 5 Canonical, Debian, Fedoraproject and 2 more 5 Ubuntu Linux, Debian Linux, Fedora and 2 more 2021-09-17 4.6 MEDIUM 7.8 HIGH
The XSLoader::load method in XSLoader in Perl does not properly locate .so files when called in a string eval, which might allow local users to execute arbitrary code via a Trojan horse library under the current working directory.
CVE-2020-14393 2 Opensuse, Perl 2 Leap, Database Interface 2020-09-28 3.6 LOW 7.1 HIGH
A buffer overflow was found in perl-DBI < 1.643 in DBI.xs. A local attacker who is able to supply a string longer than 300 characters could cause an out-of-bounds write, affecting the availability of the service or integrity of data.
CVE-2016-2381 5 Canonical, Debian, Opensuse and 2 more 10 Ubuntu Linux, Debian Linux, Opensuse and 7 more 2020-09-10 5.0 MEDIUM 7.5 HIGH
Perl might allow context-dependent attackers to bypass the taint protection mechanism in a child process via duplicate environment variables in envp.
CVE-2018-12015 6 Apple, Archive\, Canonical and 3 more 9 Mac Os X, \, Ubuntu Linux and 6 more 2020-08-24 6.4 MEDIUM 7.5 HIGH
In Perl through 5.26.2, the Archive::Tar module allows remote attackers to bypass a directory-traversal protection mechanism, and overwrite arbitrary files, via an archive file containing a symlink and a regular file with the same name.
CVE-2017-12837 1 Perl 1 Perl 2020-07-15 5.0 MEDIUM 7.5 HIGH
Heap-based buffer overflow in the S_regatom function in regcomp.c in Perl 5 before 5.24.3-RC1 and 5.26.x before 5.26.1-RC1 allows remote attackers to cause a denial of service (out-of-bounds write) via a regular expression with a '\N{}' escape and the case-insensitive modifier.
CVE-2015-8607 3 Canonical, Debian, Perl 3 Ubuntu Linux, Debian Linux, Pathtools 2020-07-15 7.5 HIGH 7.3 HIGH
The canonpath function in the File::Spec module in PathTools before 3.62, as used in Perl, does not properly preserve the taint attribute of data, which might allow context-dependent attackers to bypass the taint protection mechanism via a crafted string.
CVE-2018-6798 4 Canonical, Debian, Perl and 1 more 5 Ubuntu Linux, Debian Linux, Perl and 2 more 2020-07-15 5.0 MEDIUM 7.5 HIGH
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.
CVE-2016-1238 2 Debian, Perl 2 Debian Linux, Perl 2018-12-16 7.2 HIGH 7.8 HIGH
(1) cpan/Archive-Tar/bin/ptar, (2) cpan/Archive-Tar/bin/ptardiff, (3) cpan/Archive-Tar/bin/ptargrep, (4) cpan/CPAN/scripts/cpan, (5) cpan/Digest-SHA/shasum, (6) cpan/Encode/bin/enc2xs, (7) cpan/Encode/bin/encguess, (8) cpan/Encode/bin/piconv, (9) cpan/Encode/bin/ucmlint, (10) cpan/Encode/bin/unidump, (11) cpan/ExtUtils-MakeMaker/bin/instmodsh, (12) cpan/IO-Compress/bin/zipdetails, (13) cpan/JSON-PP/bin/json_pp, (14) cpan/Test-Harness/bin/prove, (15) dist/ExtUtils-ParseXS/lib/ExtUtils/xsubpp, (16) dist/Module-CoreList/corelist, (17) ext/Pod-Html/bin/pod2html, (18) utils/c2ph.PL, (19) utils/h2ph.PL, (20) utils/h2xs.PL, (21) utils/libnetcfg.PL, (22) utils/perlbug.PL, (23) utils/perldoc.PL, (24) utils/perlivp.PL, and (25) utils/splain.PL in Perl 5.x before 5.22.3-RC2 and 5.24 before 5.24.1-RC2 do not properly remove . (period) characters from the end of the includes directory array, which might allow local users to gain privileges via a Trojan horse module under the current working directory.
CVE-2015-8853 2 Fedoraproject, Perl 2 Fedora, Perl 2018-05-02 5.0 MEDIUM 7.5 HIGH
The (1) S_reghop3, (2) S_reghop4, and (3) S_reghopmaybe3 functions in regexec.c in Perl before 5.24.0 allow context-dependent attackers to cause a denial of service (infinite loop) via crafted utf-8 data, as demonstrated by "a\x80."
CVE-2016-1246 3 Dbd-mysql Project, Debian, Perl 3 Dbd-mysql, Debian Linux, Perl 2017-11-13 5.0 MEDIUM 7.5 HIGH
Buffer overflow in the DBD::mysql module before 4.037 for Perl allows context-dependent attackers to cause a denial of service (crash) via vectors related to an error message.
