    Summary: Nokogiri implementation of libxslt lacks integer overflow checks

    Details: The xsltAddTextString function in transform.c in libxslt 1.1.29, as used in Nokogiri prior to 1.7.2, lacked a check for integer overflow during a size calculation, which allowed a remote attacker to perform an out of bounds memory write via a crafted HTML page.
