https://notcve.org/view.php?id=CVE-2020-12243
In filter.c in slapd in OpenLDAP before 2.4.50, LDAP search filters with nested boolean expressions can result in denial of service (daemon crash). En el archivo filter.c en slapd en OpenLDAP versiones anteriores a 2.4.50, los filtros de búsqueda de LDAP con expresiones booleanas anidadas pueden resultar en una denegación de servicio (bloqueo del demonio). • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00016.html https://bugs.openldap.org/show_bug.cgi?id=9202 https://git.openldap.org/openldap/openldap/-/blob/OPENLDAP_REL_ENG_2_4/CHANGES https://git.openldap.org/openldap/openldap/-/commit/98464c11df8247d6a11b52e294ba5dd4f0380440 https://lists.debian.org/debian-lts-announce/2020/05/msg00001.html https://security.netapp.com/advisory/ntap-20200511-0003 https://support.apple.com/kb/HT211289 https://usn.ubuntu.com/4352-1 https&# • CWE-400: Uncontrolled Resource Consumption CWE-674: Uncontrolled Recursion •
CVSS: 9.8EPSS: 0%CPEs: 3EXPL: 1CVE-2020-12268 – jbig2dec: heap-based buffer overflow in jbig2_image_compose in jbig2_image.c
https://notcve.org/view.php?id=CVE-2020-12268
jbig2_image_compose in jbig2_image.c in Artifex jbig2dec before 0.18 has a heap-based buffer overflow. La función jbig2_image_compose en el archivo jbig2_image.c en Artifex jbig2dec versiones anteriores a la versión 0.18, tiene un desbordamiento de búfer en la región heap de la memoria. An integer overflow was found in jbig2dec, which causes an out-of-bounds read/write in the jbig2_image_compose function. This flaw could potentially result in the execution of code on the system. Applications that use jbig2dec with untrusted input may be vulnerable to this flaw. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00034.html https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=20332 https://github.com/ArtifexSoftware/jbig2dec/commit/0726320a4b55078e9d8deb590e477d598b3da66e https://github.com/ArtifexSoftware/jbig2dec/compare/0.17...0.18 https://lists.debian.org/debian-lts-announce/2021/10/msg00023.html https://access.redhat.com/security/cve/CVE-2020-12268 https://bugzilla.redhat.com/show_bug.cgi?id=1848518 • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2020-12137
GNU Mailman 2.x before 2.1.30 uses the .obj extension for scrubbed application/octet-stream MIME parts. This behavior may contribute to XSS attacks against list-archive visitors, because an HTTP reply from an archive web server may lack a MIME type, and a web browser may perform MIME sniffing, conclude that the MIME type should have been text/html, and execute JavaScript code. GNU Mailman versiones 2.x anteriores a la versión 2.1.30, usa una extensión .obj para partes MIME de aplications/octet-stream. Este comportamiento puede contribuir a ataques de tipo XSS contra visitantes de archivos de lista, porque una respuesta HTTP desde un servidor web de archivo puede carecer de un tipo MIME, y un navegador web puede realizar rastreo del MIME, concluir que el tipo MIME debería haber sido text/html, y ejecutar código JavaScript. • http://bazaar.launchpad.net/~mailman-coders/mailman/2.1/view/head:/NEWS http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00047.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00063.html http://www.openwall.com/lists/oss-security/2020/04/24/3 https://lists.debian.org/debian-lts-announce/2020/05/msg00002.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6YCMGTTOXXCVM4O6CYZLTZDX6YLYORNF https://lists.fedoraproject.org • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

CVSS: 9.8EPSS: 13%CPEs: 13EXPL: 0CVE-2020-11945 – squid: improper access restriction upon Digest Authentication nonce replay could lead to remote code execution
https://notcve.org/view.php?id=CVE-2020-11945
An issue was discovered in Squid before 5.0.2. A remote attacker can replay a sniffed Digest Authentication nonce to gain access to resources that are otherwise forbidden. This occurs because the attacker can overflow the nonce reference counter (a short integer). Remote code execution may occur if the pooled token credentials are freed (instead of replayed as valid credentials). Se detectó un problema en Squid versiones anteriores a 5.0.2. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00018.html http://master.squid-cache.org/Versions/v4/changesets/squid-4-eeebf0f37a72a2de08348e85ae34b02c34e9a811.patch http://www.openwall.com/lists/oss-security/2020/04/23/2 http://www.squid-cache.org/Versions/v4/changesets/squid-4-eeebf0f37a72a2de08348e85ae34b02c34e9a811.patch https://bugzilla.suse.com/show_bug.cgi?id=1170313 https://github.com/squid-cache/squid/commit/eeebf0f37a72a2de08348e85ae34b02c34e9a811 https://github.com/squid-cache/squid/pull/585 • CWE-190: Integer Overflow or Wraparound CWE-284: Improper Access Control •
