Description

XML::Parser versions through 2.47 for Perl could overflow the pre-allocated buffer size cause a heap corruption (double free or corruption) and crashes.<br /> <br /> A :utf8 PerlIO layer, parse_stream() in Expat.xs could overflow the XML input buffer because Perl&#39;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.
