Synopsis
========

A vulnerability in PCRE library allows remote attackers to cause a
Denial of Service condition.

pattern matching using the same syntax and semantics as Perl 5.

It was found that the compile_bracket_matchingpath function in
pcre_jit_compile.c in PCRE library is vulnerable to an out-of-bounds
read.

Impact
======

A remote attacker could possibly cause a Denial of Service condition
via a special crafted regular expression.

Workaround
