CVE-2006-10002: Toddr Xml::parser

High severity, CVSS 7.5. EPSS: 0.6% chance of exploitation in the next 30 days.

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.

Affected products

• Toddr Xml::parser: before 2.48 (fixed in 2.48)
