Multiple vulnerabilities were discovered in the implementation of the Perl programming language. The Common Vulnerabilities and Exposures project identifies the following problems:

CVE-2018-18311

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

Eiichi Tsukata discovered that a crafted regular expression could cause a heap-based buffer overflow read during compilation which leads to information leak.

CVE-2018-18314

Jakub Wilk discovered that a specially crafted regular expression could lead to a heap-based buffer overflow.

For the stable distribution (stretch), these problems have been fixed in version 5.24.1-3+deb9u5.
