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.
CVSS 3 base score: 9.8
5.18 - 5.28
looks to me like this was introduced by: https://perl5.git.perl.org/perl.git/commit/6798c95dd27b33efd71f394c18649af7bbaf42b7 trusty doesn't look affected
