Summary
perl vulnerabilities
Details

It was discovered that Perl incorrectly handled certain regular expressions with an invalid backreference. An attacker could use this issue to cause Perl to crash, resulting in a denial of service, or possibly execute arbitrary code. (CVE-2013-7422)

Markus Vervier discovered that Perl incorrectly handled nesting in the Data::Dumper module. An attacker could use this issue to cause Perl to consume memory and crash, resulting in a denial of service. (CVE-2014-4330)

Stephane Chazelas discovered that Perl incorrectly handled duplicate environment variables. An attacker could possibly use this issue to bypass the taint protection mechanism. (CVE-2016-2381)
