https://notcve.org/view.php?id=CVE-2021-3518
There's a flaw in libxml2 in versions before 2.9.11. An attacker who is able to submit a crafted file to be processed by an application linked with libxml2 could trigger a use-after-free. The greatest impact from this flaw is to confidentiality, integrity, and availability. Se presenta un fallo en libxml2 en versiones anteriores a 2.9.11. Un atacante que pueda enviar un archivo diseñado para que sea procesado por una aplicación vinculada con libxml2 podría desencadenar un uso de la memoria previamente liberada. • http://seclists.org/fulldisclosure/2021/Jul/54 http://seclists.org/fulldisclosure/2021/Jul/55 http://seclists.org/fulldisclosure/2021/Jul/58 http://seclists.org/fulldisclosure/2021/Jul/59 https://bugzilla.redhat.com/show_bug.cgi?id=1954242 https://lists.apache.org/thread.html/r58af02e294bd07f487e2c64ffc0a29b837db5600e33b6e698b9d696b%40%3Cissues.bookkeeper.apache.org%3E https://lists.apache.org/thread.html/rf4c02775860db415b4955778a131c2795223f61cb8c6a450893651e4%40%3Cissues.bookkeeper.apache.org%3E https://lists.debian.org/d • CWE-416: Use After Free •
CVSS: 7.5EPSS: 1%CPEs: 25EXPL: 0CVE-2021-3537 – libxml2: NULL pointer dereference when post-validating mixed content parsed in recovery mode
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 •
