CVE-2022-23852 – expat: Integer overflow in function XML_GetBuffer
https://notcve.org/view.php?id=CVE-2022-23852
Expat (aka libexpat) before 2.4.4 has a signed integer overflow in XML_GetBuffer, for configurations with a nonzero XML_CONTEXT_BYTES. Expat (también se conoce como libexpat) versiones anteriores a 2.4.4, presenta un desbordamiento de enteros con signo en la función XML_GetBuffer, para configuraciones con un XML_CONTEXT_BYTES no nulo 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. • https://cert-portal.siemens.com/productcert/pdf/ssa-484086.pdf https://github.com/libexpat/libexpat/pull/550 https://lists.debian.org/debian-lts-announce/2022/03/msg00007.html https://security.gentoo.org/glsa/202209-24 https://security.netapp.com/advisory/ntap-20220217-0001 https://www.debian.org/security/2022/dsa-5073 https://www.oracle.com/security-alerts/cpuapr2022.html https://www.tenable.com/security/tns-2022-05 https://access.redhat.com/security/cve/CVE-2022-23852 https& • CWE-190: Integer Overflow or Wraparound •
CVE-2022-23437 – Infinite loop within Apache XercesJ xml parser
https://notcve.org/view.php?id=CVE-2022-23437
There's a vulnerability within the Apache Xerces Java (XercesJ) XML parser when handling specially crafted XML document payloads. This causes, the XercesJ XML parser to wait in an infinite loop, which may sometimes consume system resources for prolonged duration. This vulnerability is present within XercesJ version 2.12.1 and the previous versions. Se presenta una vulnerabilidad en el analizador XML de Apache Xerces Java (XercesJ) cuando maneja cargas útiles de documentos XML especialmente diseñados. Esto causa que el analizador XML de XercesJ espere en un bucle infinito, lo que a veces puede consumir recursos del sistema durante un tiempo prolongado. • http://www.openwall.com/lists/oss-security/2022/01/24/3 https://lists.apache.org/thread/6pjwm10bb69kq955fzr1n0nflnjd27dl https://security.netapp.com/advisory/ntap-20221028-0005 https://www.oracle.com/security-alerts/cpuapr2022.html https://www.oracle.com/security-alerts/cpujul2022.html https://access.redhat.com/security/cve/CVE-2022-23437 https://bugzilla.redhat.com/show_bug.cgi?id=2047200 • CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
CVE-2022-23307 – A deserialization flaw in the Chainsaw component of Log4j 1 can lead to malicious code execution.

CVE-2020-9493 identified a deserialization issue that was present in Apache Chainsaw. Prior to Chainsaw V2.0 Chainsaw was a component of Apache Log4j 1.2.x where the same issue exists. CVE-2020-9493 identificó un problema de deserialización presente en Apache Chainsaw. Versiones anteriores a Chainsaw V2.0 Chainsaw era un componente de Apache Log4j versiones 1.2.x donde se presenta el mismo problema A flaw was found in the log4j 1.x chainsaw component, where the contents of certain log entries are deserialized and possibly permit code execution.

CVE-2022-23305 – SQL injection in JDBC Appender in Apache Log4j V1
https://notcve.org/view.php?id=CVE-2022-23305
By design, the JDBCAppender in Log4j 1.2.x accepts an SQL statement as a configuration parameter where the values to be inserted are converters from PatternLayout. The message converter, %m, is likely to always be included. This allows attackers to manipulate the SQL by entering crafted strings into input fields or headers of an application that are logged allowing unintended SQL queries to be executed. Note this issue only affects Log4j 1.x when specifically configured to use the JDBCAppender, which is not the default. Beginning in version 2.0-beta8, the JDBCAppender was re-introduced with proper support for parameterized SQL queries and further customization over the columns written to in logs. • http://www.openwall.com/lists/oss-security/2022/01/18/4 https://lists.apache.org/thread/pt6lh3pbsvxqlwlp4c5l798dv2hkc85y https://logging.apache.org/log4j/1.2/index.html https://security.netapp.com/advisory/ntap-20220217-0007 https://www.oracle.com/security-alerts/cpuapr2022.html https://www.oracle.com/security-alerts/cpujul2022.html https://access.redhat.com/security/cve/CVE-2022-23305 https://bugzilla.redhat.com/show_bug.cgi?id=2041959 • CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') •
CVE-2022-23302 – Deserialization of untrusted data in JMSSink in Apache Log4j 1.x
https://notcve.org/view.php?id=CVE-2022-23302
JMSSink in all versions of Log4j 1.x is vulnerable to deserialization of untrusted data when the attacker has write access to the Log4j configuration or if the configuration references an LDAP service the attacker has access to. The attacker can provide a TopicConnectionFactoryBindingName configuration causing JMSSink to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-4104. Note this issue only affects Log4j 1.x when specifically configured to use JMSSink, which is not the default. Apache Log4j 1.2 reached end of life in August 2015. Users should upgrade to Log4j 2 as it addresses numerous other issues from the previous versions. • http://www.openwall.com/lists/oss-security/2022/01/18/3 https://lists.apache.org/thread/bsr3l5qz4g0myrjhy9h67bcxodpkwj4w https://logging.apache.org/log4j/1.2/index.html https://security.netapp.com/advisory/ntap-20220217-0006 https://www.oracle.com/security-alerts/cpuapr2022.html https://www.oracle.com/security-alerts/cpujul2022.html https://access.redhat.com/security/cve/CVE-2022-23302 https://bugzilla.redhat.com/show_bug.cgi?id=2041949 • CWE-502: Deserialization of Untrusted Data •
