Use-after-free vulnerability in the XSLT ProcessingInstruction implementation in Blink, as used in Google Chrome before 29.0.1547.57, allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to an applyXSLTransform call involving (1) an HTML document or (2) an xsl:processing-instruction element that is still in the process of loading.
