FreeBSD : pcre -- regular expression buffer overflow (b971d2a6-1670-11da-978e-0001020eed82)

high Nessus Plugin ID 21502
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 FreeBSD host is missing one or more security-related updates.


The pcre library is vulnerable to a buffer overflow vulnerability due to insufficient validation of quantifier values. This could lead execution of arbitrary code with the permissions of the program using pcre by way of a specially crated regular expression.


Update the affected packages.
