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-2023-47100 1 Perl 1 Perl 2023-12-14 N/A 9.8 CRITICAL
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-2022-48522 1 Perl 1 Perl 2023-08-28 N/A 9.8 CRITICAL
In Perl 5.34.0, function S_find_uninit_var in sv.c has a stack-based crash that can lead to remote code execution or local privilege escalation.
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-2020-10543 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

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.
