Packages

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)
