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.

Perl before 5.26.3 and 5.28.x before 5.28.1 has a buffer overflow via a crafted regular expression that triggers invalid write operations.
CVE-2018-12015 6 Apple, Archive\, Canonical and 3 more 9 Mac Os X, \, Ubuntu Linux and 6 more 2026-06-17 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-2017-12883 1 Perl 1 Perl 2026-06-17 6.4 MEDIUM 9.1 CRITICAL
Buffer overflow in the S_grok_bslash_N 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 disclose sensitive information or cause a denial of service (application crash) via a crafted regular expression with an invalid '\N{U+...}' escape.
CVE-2017-12837 1 Perl 1 Perl 2026-06-17 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-2017-12814 2 Microsoft, Perl 2 Windows, Perl 2026-06-17 7.5 HIGH 9.8 CRITICAL
Stack-based buffer overflow in the CPerlHost::Add method in win32/perlhost.h in Perl before 5.24.3-RC1 and 5.26.x before 5.26.1-RC1 on Windows allows attackers to execute arbitrary code via a long environment variable.

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-2016-2381 5 Canonical, Debian, Opensuse and 2 more 10 Ubuntu Linux, Debian Linux, Opensuse and 7 more 2026-06-17 5.0 MEDIUM 7.5 HIGH
