CVE-2010-1330: XSS in the regular expression engine when processing invalid UTF-8 byte sequences

November 23, 2012 (updated August 16, 2017)

The regular expression engine in this package, when $KCODE is set to ‘u’, does not properly handle characters immediately after a UTF-8 character, which allows remote attackers to conduct cross-site scripting (XSS) attacks via a crafted string.
