Summary

Details

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.

Summary

libxml-parser-perl vulnerabilities

Details

It was discovered that XML::Parser incorrectly handled certain multi-byte UTF-8 characters. If a user or automated system were tricked into processing specially crafted XML data, a remote attacker could use this issue to cause XML::Parser to crash, resulting in a denial of service or to possibly execute arbitrary code. (CVE-2006-10002)

It was discovered that XML::Parser incorrectly handled very deep element nesting. If a user or automated system were tricked into processing specially crafted XML data, a remote attacker could use this issue to cause XML::Parser to crash, resulting in a denial of service or to possibly execute arbitrary code (CVE-2006-10003)
