CVE-2020-12723
7.5 - High
- June 05, 2020
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-2018-18314
9.8 - Critical
- December 07, 2018
Perl before 5.26.3 has a buffer overflow via a crafted regular expression that triggers invalid write operations.
Buffer Overflow

CVE-2018-18312
9.8 - Critical
- December 05, 2018
Perl before 5.26.3 and 5.28.0 before 5.28.1 has a buffer overflow via a crafted regular expression that triggers invalid write operations.
Buffer Overflow
In Perl through 5.26.2, the Archive::Tar module
CVE-2018-12015
7.5 - High
- June 07, 2018
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-2018-6797
9.8 - Critical
- April 17, 2018
