Descriptions
Use after free in libxml2 before 2.9.5, as used in Google Chrome prior to 63.0.3239.84 and other products, allowed a remote attacker to potentially exploit heap corruption via a crafted HTML page.
Uso de memoria previamente liberada en libxml2 en versiones anteriores a la 2.9.5, tal y como se emplea en Google Chrome en versiones anteriores a la 63.0.3239.84 y otros productos, permitía que un atacante remoto pudiese explotar una corrupción de memoria dinámica (heap) mediante una página HTML manipulada.
A use-after-free flaw was found in the libxml2 library. An attacker could use this flaw to cause an application linked against libxml2 to crash when parsing a specially crafted XML file.
