Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

SO-AND-SO reports :

CVE-2017-12814: $ENV{$key} stack-based buffer overflow on Windows

A possible stack-based buffer overflow in the %ENV code on Windows has been fixed by removing the buffer completely since it was superfluous anyway.

CVE-2017-12837: Heap buffer overflow in regular expression compiler

Compiling certain regular expression patterns with the case-insensitive modifier could cause a heap buffer overflow and crash perl. This has now been fixed.

CVE-2017-12883: Buffer over-read in regular expression parser

For certain types of syntax error in a regular expression pattern, the error message could either contain the contents of a random, possibly large, chunk of memory, or could crash perl. This has now been fixed.

Solution

Update the affected packages.
