CVE-2017-12883

A heap buffer overread was found in perl's grok_bslash_N() function, which is used in the compilation of Unicode nodes in regular expressions, possibly leading to crash or dump of memory segments via the error output. An attacker, able to provide a specially crafted regular expression, could look for sensible information in the error message, or crash perl.
