A NULL pointer dereference flaw was found in ImageMagick in versions prior to 7.0.10-31 in ReadSVGImage() in coders/svg.c. This issue is due to not checking the return value from libxml2's xmlCreatePushParserCtxt() and uses the value directly, which leads to a crash and segmentation fault. Se ha encontrado un fallo de desreferencia de puntero NULL en ImageMagick en versiones anteriores a 7.0.10-31 en la función ReadSVGImage() en el archivo coders/svg.c. Este problema es debido a que no es comprobado el valor de retorno de xmlCreatePushParserCtxt() de libxml2 y es usado el valor directamente, conllevando a un fallo de bloqueo y segmentación • https://bugzilla.redhat.com/show_bug.cgi?id=1970569 https://github.com/ImageMagick/ImageMagick/issues/2624 https://lists.debian.org/debian-lts-announce/2022/05/msg00018.html https://lists.debian.org/debian-lts-announce/2023/03/msg00008.html • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2021-45417
AIDE before 0.17.4 allows local users to obtain root privileges via crafted file metadata (such as XFS extended attributes or tmpfs ACLs), because of a heap-based buffer overflow. AIDE versiones anteriores a 0.17.4, permite a usuarios locales obtener privilegios de root por medio de metadatos de archivo diseñados (como atributos extendidos de XFS o ACLs de tmpfs), debido a un desbordamiento de búfer en la región heap de la memoria A heap-based buffer overflow vulnerability in the base64 functions of AIDE, an advanced intrusion detection system. An attacker could crash the program and possibly execute arbitrary code through large (<16k) extended file attributes or ACL. • http://www.openwall.com/lists/oss-security/2022/01/20/3 https://lists.debian.org/debian-lts-announce/2022/01/msg00024.html https://security.gentoo.org/glsa/202311-07 https://www.debian.org/security/2022/dsa-5051 https://www.ipi.fi/pipermail/aide/2022-January/001713.html https://www.openwall.com/lists/oss-security/2022/01/20/3 https://access.redhat.com/security/cve/CVE-2021-45417 https://bugzilla.redhat.com/show_bug.cgi?id=2041489 • CWE-787: Out-of-bounds Write •
CVSS: 7.5EPSS: 15%CPEs: 72EXPL: 0CVE-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 •

https://notcve.org/view.php?id=CVE-2021-3941
In ImfChromaticities.cpp routine RGBtoXYZ(), there are some division operations such as `float Z = (1 - chroma.white.x - chroma.white.y) * Y / chroma.white.y;` and `chroma.green.y * (X + Z))) / d;` but the divisor is not checked for a 0 value. A specially crafted file could trigger a divide-by-zero condition which could affect the availability of programs linked with OpenEXR. En la rutina RGBtoXYZ() del archivo ImfChromaticities.cpp, se presentan algunas operaciones de división como "float Z = (1 - chroma.white.x - chroma.white.y) * Y / chroma.white.y;" y "chroma.green.y * (X + Z)) / d;" pero no es comprobado que el divisor tenga un valor 0.
