https://notcve.org/view.php?id=CVE-2021-45078
stab_xcoff_builtin_type in stabs.c in GNU Binutils through 2.37 allows attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact, as demonstrated by an out-of-bounds write. NOTE: this issue exists because of an incorrect fix for CVE-2018-12699. La función stab_xcoff_builtin_type en el archivo stabs.c en GNU Binutils versiones hasta 2.37, permite a atacantes causar una denegación de servicio (desbordamiento de búfer basado en la pila) o posiblemente tener otro impacto no especificado, como lo demuestra una escritura fuera de límites. NOTA: este problema se presenta debido a una corrección incorrecta de CVE-2018-12699 • https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/UQBH244M5PV6S6UMHUTCVCWFZDX7Y4M6 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/UUHLDDT3HH7YEY6TX7IJRGPJUTNNVEL3 https://security.gentoo.org/glsa/202208-30 https://security.netapp.com/advisory/ntap-20220107-0002 https://sourceware.org/bugzilla/show_bug.cgi?id=28694 https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git%3Bh=161e87d12167b1e36193385485c1f6ce92f74f02 • CWE-787: Out-of-bounds Write •
CVE-2021-4008 – X.Org Server SProcRenderCompositeGlyphs Out-Of-Bounds Access Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2021-4008
A flaw was found in xorg-x11-server in versions before 21.1.2 and before 1.20.14. An out-of-bounds access can occur in the SProcRenderCompositeGlyphs function. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

CVE-2021-43518
https://notcve.org/view.php?id=CVE-2021-43518
Teeworlds up to and including 0.7.5 is vulnerable to Buffer Overflow. A map parser does not validate m_Channels value coming from a map file, leading to a buffer overflow. A malicious server may offer a specially crafted map that will overwrite client's stack causing denial of service or code execution. Teeworlds versiones hasta 0.7.5 incluyéndola, es vulnerable a un desbordamiento del búfer. Un analizador de mapas no comprueba el valor m_Channels procedente de un archivo de mapas, conllevando a un desbordamiento del búfer. • https://github.com/teeworlds/teeworlds/issues/2981 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JIYZ7EVY6NZBM7FQF6GVUARYO6MKSEAT https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/OS2LI2RHQNUKUT3FKWYHRC27PLRWCHMZ https://mmmds.pl/fuzzing-map-parser-part-1-teeworlds • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
CVE-2021-45046 – Apache Log4j2 Deserialization of Untrusted Data Vulnerability
https://notcve.org/view.php?id=CVE-2021-45046
It was found that the fix to address CVE-2021-44228 in Apache Log4j 2.15.0 was incomplete in certain non-default configurations. This could allows attackers with control over Thread Context Map (MDC) input data when the logging configuration uses a non-default Pattern Layout with either a Context Lookup (for example, $${ctx:loginId}) or a Thread Context Map pattern (%X, %mdc, or %MDC) to craft malicious input data using a JNDI Lookup pattern resulting in an information leak and remote code execution in some environments and local code execution in all environments. Log4j 2.16.0 (Java 8) and 2.12.2 (Java 7) fix this issue by removing support for message lookup patterns and disabling JNDI functionality by default. Se descubrió que la corrección para abordar CVE-2021-44228 en Apache Log4j versiones 2.15.0 estaba incompleta en ciertas configuraciones no predeterminadas. Esto podría permitir a los atacantes con control sobre los datos de entrada de Thread Context Map (MDC) cuando la configuración de registro utiliza un Pattern Layout no predeterminado con un Context Lookup (por ejemplo, $${ctx:loginId}) o un Thread Context Map pattern (%X, %mdc, o %MDC) para elaborar datos de entrada maliciosos utilizando un patrón JNDI Lookup que resulta en una fuga de información y ejecución de código remoto en algunos entornos y ejecución de código local en todos los entornos. • https://github.com/BobTheShoplifter/CVE-2021-45046-Info https://github.com/thedevappsecguy/Log4J-Mitigation-CVE-2021-44228--CVE-2021-45046--CVE-2021-45105--CVE-2021-44832 https://github.com/tejas-nagchandi/CVE-2021-45046 https://github.com/pravin-pp/log4j2-CVE-2021-45046 http://www.openwall.com/lists/oss-security/2021/12/14/4 http://www.openwall.com/lists/oss-security/2021/12/15/3 http://www.openwall.com/lists/oss-security/2021/12/18/1 https://cert-portal.siemen • CWE-400: Uncontrolled Resource Consumption CWE-917: Improper Neutralization of Special Elements used in an Expression Language Statement ('Expression Language Injection') •
CVE-2021-4104 – Deserialization of untrusted data in JMSAppender in Apache Log4j 1.2
https://notcve.org/view.php?id=CVE-2021-4104
JMSAppender in Log4j 1.2 is vulnerable to deserialization of untrusted data when the attacker has write access to the Log4j configuration. The attacker can provide TopicBindingName and TopicConnectionFactoryBindingName configurations causing JMSAppender to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-44228. Note this issue only affects Log4j 1.2 when specifically configured to use JMSAppender, 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://access.redhat.com/security/cve/CVE-2021-4104 https://github.com/apache/logging-log4j2/pull/608#issuecomment-990494126 https://psirt.global.sonicwall.com/vuln-detail/SNWLID-2021-0033 https://security.gentoo.org/glsa/202209-02 https://security.gentoo.org/glsa/202310-16 https://security.gentoo.org/glsa/202312-02 https://security.gentoo.org/glsa/202312-04 https://security.netapp.com/advisory/ntap-20211223-0007 https • CWE-20: Improper Input Validation CWE-502: Deserialization of Untrusted Data •
