Jayakrishna Menon and Christophe Hauser discovered an integer
overflow vulnerability in Perl_my_setenv leading to a heap-based
buffer overflow with attacker-controlled input.
CVE-2018-18312
Eiichi Tsukata discovered that a crafted regular expression could
cause a heap-based buffer overflow write during compilation,
potentially allowing arbitrary code execution.
CVE-2018-18313

cause a heap-based buffer overflow read during compilation which
leads to information leak.
CVE-2018-18314

For the stable distribution (stretch), these problems have been fixed in
