HIGH 7.5REMOTEUPGRADE

CVE-2006-10002 is a high-severity flaw (CVSS 7.5) affecting xml\. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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 crash
