Descriptions
libxml2 2.9.8, if --with-lzma is used, allows remote attackers to cause a denial of service (infinite loop) via a crafted XML file that triggers LZMA_MEMLIMIT_ERROR, as demonstrated by xmllint, a different vulnerability than CVE-2015-8035 and CVE-2018-9251.
libxml2 2.9.8, si se emplea --with-lzma, permite que atacantes remotos provoquen una denegación de servicio (bucle infinito) mediante un archivo XML manipulado que desencadena LZMA_MEMLIMIT_ERROR, tal y como queda demostrado por xmllint. Esta vulnerabilidad es diferente de CVE-2015-8035 y CVE-2018-9251.
