https://notcve.org/view.php?id=CVE-2021-3537
A vulnerability found in libxml2 in versions before 2.9.11 shows that it did not propagate errors while parsing XML mixed content, causing a NULL dereference. If an untrusted XML document was parsed in recovery mode and post-validated, the flaw could be used to crash the application. The highest threat from this vulnerability is to system availability. Una vulnerabilidad encontrada en libxml2 en versiones anteriores a 2.9.11 muestra que no propagó errores al analizar el contenido mixto XML, causando una desreferencia de NULL. Si un documento XML que no es confiable fue analizado en modo de recuperación y pos-comprobado, el fallo podría usarse para bloquear la aplicación. • https://bugzilla.redhat.com/show_bug.cgi?id=1956522 https://lists.debian.org/debian-lts-announce/2021/05/msg00008.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BZOMV5J4PMZAORVT64BKLV6YIZAFDGX6 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/QVM4UJ3376I6ZVOYMHBNX4GY3NIV52WV https://security.gentoo.org/glsa/202107-05 https://security.netapp.com/advisory/ntap-20210625-0002 https://www.oracle.com/security-alerts/cpuapr2022.html • CWE-476: NULL Pointer Dereference •
