## Description

XML::Parser versions through 2.45 for Perl could overflow the pre-allocated
buffer size cause a heap corruption (double free or corruption) and
crashes.
A :utf8 PerlIO layer, parse\_stream() in Expat.xs could overflow the XML
input buffer because Perl's read() returns decoded characters while SvPV()
gives back multi-byte UTF-8 bytes that can exceed the pre-allocated buffer
size. This can cause heap corruption (double free or corruption) and
crashes.
