https://notcve.org/view.php?id=CVE-2018-18311
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 – perl: Directory traversal in Archive::Tar
https://notcve.org/view.php?id=CVE-2018-12015
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. En Perl hasta la versión 5.26.2, el módulo Archive::Tar permite que atacantes remotos omitan un mecanismo de protección de salto de directorio y sobrescriban archivos arbitrarios mediante un archivo comprimido que contiene un symlink y un archivo normal con el mismo nombre. It was found that the Archive::Tar module did not properly sanitize symbolic links when extracting tar archives. An attacker, able to provide a specially crafted archive for processing, could use this flaw to write or overwrite arbitrary files in the context of the Perl interpreter. • http://seclists.org/fulldisclosure/2019/Mar/49 http://www.securityfocus.com/bid/104423 http://www.securitytracker.com/id/1041048 https://access.redhat.com/errata/RHSA-2019:2097 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=900834 https://seclists.org/bugtraq/2019/Mar/42 https://security.netapp.com/advisory/ntap-20180927-0001 https://support.apple.com/kb/HT209600 https://usn.ubuntu.com/3684-1 https://usn.ubuntu.com/3684-2 https://www.debian.org/security/2018& • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-59: Improper Link Resolution Before File Access ('Link Following') •
