Integer overflow in Perl-Compatible Regular Expression (PCRE) library
before 6.7 allows context-dependent attackers to execute arbitrary code via
a regular expression containing a large number of named subpatterns
(name_count) or long subpattern names (max_name_size), which triggers a
buffer overflow. NOTE: this issue was originally subsumed by
CVE-2006-7224, but that CVE has been REJECTED and split.
