https://notcve.org/view.php?id=CVE-2018-14567
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. • http://www.securityfocus.com/bid/105198 https://gitlab.gnome.org/GNOME/libxml2/commit/2240fbf5912054af025fb6e01e26375100275e74 https://lists.debian.org/debian-lts-announce/2018/09/msg00035.html https://lists.debian.org/debian-lts-announce/2020/09/msg00009.html https://usn.ubuntu.com/3739-1 https://access.redhat.com/security/cve/CVE-2018-14567 https://bugzilla.redhat.com/show_bug.cgi?id=1619875 • CWE-400: Uncontrolled Resource Consumption CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •

https://notcve.org/view.php?id=CVE-2016-9597
It was found that Red Hat JBoss Core Services erratum RHSA-2016:2957 for CVE-2016-3705 did not actually include the fix for the issue found in libxml2, making it vulnerable to a Denial of Service attack due to a Stack Overflow. This is a regression CVE for the same issue as CVE-2016-3705. Se ha descubierto que el erratum de Red Hat JBoss Core Services RHSA-2016:2957 para CVE-2016-3705 no incluía la solución al problema en libxml2, lo que lo hace vulnerable a un ataque de denegación de servicio (DoS) debido a un desbordamiento de pila. Este es un CVE de regresión para el mismo problema que CVE-2016-3705. • http://www.securityfocus.com/bid/98567 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2016-9597 https://access.redhat.com/security/cve/CVE-2016-9597 https://bugzilla.redhat.com/show_bug.cgi?id=1408305 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-674: Uncontrolled Recursion •

https://notcve.org/view.php?id=CVE-2018-14404
A NULL pointer dereference vulnerability exists in the xpath.c:xmlXPathCompOpEval() function of libxml2 through 2.9.8 when parsing an invalid XPath expression in the XPATH_OP_AND or XPATH_OP_OR case. Applications processing untrusted XSL format inputs with the use of the libxml2 library may be vulnerable to a denial of service attack due to a crash of the application. Existe una vulnerabilidad de desreferencia de puntero NULL en la función xpath.c:xmlXPathCompOpEval() de libxml2 hasta la versión 2.9.8 al analizar una expresión XPath inválida en los casos XPATH_OP_AND o XPATH_OP_OR. Las aplicaciones que procesan entradas de formato XLS no fiables mediante la biblioteca libxml2 podrían ser vulnerables a un ataque de denegación de servicio (DoS) debido al cierre inesperado de la aplicación. A null pointer dereference vulnerability exists in the xpath.c:xmlXPathCompOpEval() function of libxml2 when parsing invalid XPath expression. • https://access.redhat.com/errata/RHSA-2019:1543 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=901817 https://bugzilla.redhat.com/show_bug.cgi?id=1595985 https://gitlab.gnome.org/GNOME/libxml2/issues/10 https://lists.debian.org/debian-lts-announce/2018/09/msg00035.html https://lists.debian.org/debian-lts-announce/2020/09/msg00009.html https://security.netapp.com/advisory/ntap-20190719-0002 https://usn.ubuntu.com/3739-1 https://usn.ubuntu.com/3739-2 https://acc • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2017-18258
The xz_head function in xzlib.c in libxml2 before 2.9.6 allows remote attackers to cause a denial of service (memory consumption) via a crafted LZMA file, because the decoder functionality does not restrict memory usage to what is required for a legitimate file. La función xz_head en xzlib.c en libxml2, en versiones anteriores a la 2.9.6, permite que atacantes remotos provoquen una denegación de servicio (consumo de memoria) mediante un archivo LZMA. Esto se dene a que la funcionalidad de descifrado no restringe el uso de memoria a lo que se requiere para un archivo legítimo. • https://git.gnome.org/browse/libxml2/commit/?id=e2a9122b8dde53d320750451e9907a7dcb2ca8bb https://kc.mcafee.com/corporate/index?page=content&id=SB10284 https://lists.debian.org/debian-lts-announce/2018/09/msg00035.html https://lists.debian.org/debian-lts-announce/2020/09/msg00009.html https://security.netapp.com/advisory/ntap-20190719-0001 https://usn.ubuntu.com/3739-1 https://access.redhat.com/security/cve/CVE-2017-18258 https://bugzilla.redhat.com/show_bug.cgi?id=1566749 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
