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 •

There's a flaw in Python 3's pydoc. A local or adjacent attacker who discovers or is able to convince another local or adjacent user to start a pydoc server could access the server and use it to disclose sensitive information belonging to the other user that they would not normally be able to access. The highest risk of this flaw is to data confidentiality. This flaw affects Python versions before 3.8.9, Python versions before 3.9.3 and Python versions before 3.10.0a7. Se presenta un fallo en pydoc de Python versión 3. • https://bugzilla.redhat.com/show_bug.cgi?id=1935913 https://lists.debian.org/debian-lts-announce/2021/04/msg00005.html https://lists.debian.org/debian-lts-announce/2023/06/msg00039.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/25HVHLBGO2KNPXJ3G426QEYSSCECJDU5 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/BF2K7HEWADHN6P52R3QLIOX27U3DJ4HI https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message&#x • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

A flaw was found in dnsmasq in versions before 2.85. When configured to use a specific server for a given network interface, dnsmasq uses a fixed port while forwarding queries. An attacker on the network, able to find the outgoing port used by dnsmasq, only needs to guess the random transmission ID to forge a reply and get it accepted by dnsmasq. This flaw makes a DNS Cache Poisoning attack much easier. The highest threat from this vulnerability is to data integrity. • https://bugzilla.redhat.com/show_bug.cgi?id=1939368 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CVTJUOFFFHINLKWAOC2ZSC5MOPD4SJ24 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FHG7GWSQWKF7JXIMLOGJBKZWBB4VIAJ7 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/GHURNEHHUBSW45KMIZ4FNBCSUPWPGV5V https://security.gentoo.org/glsa/202105-20 https://www.oracle.com/security-alerts/cpujan2022.html https://access • CWE-358: Improperly Implemented Security Check for Standard •
