An attacker could use this issue to cause Perl to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2018-18311) Eiichi Tsukata discovered that Perl incorrectly handled certain regular expressions. An attacker could use this issue to cause Perl to crash, resulting in a denial of service, or possibly execute arbitrary code.

    description 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.
