SO-AND-SO reports:

CVE-2017-12814: $ENV{$key} stack buffer overflow on Windows A possible stack 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.
