https://notcve.org/view.php?id=CVE-2021-46143
In doProlog in xmlparse.c in Expat (aka libexpat) before 2.4.3, an integer overflow exists for m_groupSize. En la función doProlog en el archivo xmlparse.c en Expat (también se conoce como libexpat) versiones anteriores a 2.4.3, se presenta un desbordamiento de enteros para m_groupSize. expat (libexpat) is susceptible to a software flaw that causes process interruption. When processing a large number of prefixed XML attributes on a single tag can libexpat can terminate unexpectedly due to integer overflow. The highest threat from this vulnerability is to availability, confidentiality and integrity. • http://www.openwall.com/lists/oss-security/2022/01/17/3 https://cert-portal.siemens.com/productcert/pdf/ssa-484086.pdf https://github.com/libexpat/libexpat/issues/532 https://github.com/libexpat/libexpat/pull/538 https://security.gentoo.org/glsa/202209-24 https://security.netapp.com/advisory/ntap-20220121-0006 https://www.debian.org/security/2022/dsa-5073 https://www.tenable.com/security/tns-2022-05 https://access.redhat.com/security/cve/CVE-2021-46143 https://bu • CWE-190: Integer Overflow or Wraparound •

https://notcve.org/view.php?id=CVE-2021-45960
In Expat (aka libexpat) before 2.4.3, a left shift by 29 (or more) places in the storeAtts function in xmlparse.c can lead to realloc misbehavior (e.g., allocating too few bytes, or only freeing memory). En Expat (también se conoce como libexpat) versiones anteriores a 2.4.3, un desplazamiento a la izquierda por 29 (o más) lugares en la función storeAtts en el archivo xmlparse.c puede conllevar a un comportamiento incorrecto de reasignación (por ejemplo, asignar muy pocos bytes, o sólo liberar memoria). expat (libexpat) is susceptible to a software flaw that causes process interruption. When processing a large number of prefixed XML attributes on a single tag can libexpat can terminate unexpectedly due to buffer overrun. The highest threat from this vulnerability is to availability. • http://www.openwall.com/lists/oss-security/2022/01/17/3 https://bugzilla.mozilla.org/show_bug.cgi?id=1217609 https://cert-portal.siemens.com/productcert/pdf/ssa-484086.pdf https://github.com/libexpat/libexpat/issues/531 https://github.com/libexpat/libexpat/pull/534 https://security.gentoo.org/glsa/202209-24 https://security.netapp.com/advisory/ntap-20220121-0004 https://www.debian.org/security/2022/dsa-5073 https://www.tenable.com/security/tns-2022-05 https://acces • CWE-130: Improper Handling of Length Parameter Inconsistency CWE-682: Incorrect Calculation •
