Debian DSA-3982-1 : perl - security update

critical Nessus Plugin ID 103392
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote Debian host is missing a security-related update.


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

- CVE-2017-12837 Jakub Wilk reported a heap buffer overflow flaw in the regular expression compiler, allowing a remote attacker to cause a denial of service via a specially crafted regular expression with the case-insensitive modifier.

- CVE-2017-12883 Jakub Wilk reported a buffer over-read flaw in the regular expression parser, allowing a remote attacker to cause a denial of service or information leak.


Upgrade the perl packages.

For the oldstable distribution (jessie), these problems have been fixed in version 5.20.2-3+deb8u9.

For the stable distribution (stretch), these problems have been fixed in version 5.24.1-3+deb9u2.
