Heap-based buffer overflow in the S_regatom function in regcomp.c in Perl 5 before 5.24.3-RC1 and 5.26.x before 5.26.1-RC1 allows remote attackers to cause a denial of service (out-of-bounds write) via a regular expression with a '\N{}' escape and the case-insensitive modifier.

An update of the perl package has been released.

According to its self-reported version number, the remote pfSense install is affected by multiple vulnerabilities as stated in the referenced vendor advisories.

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.

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.
