CVSS: 8.2EPSS: 0%CPEs: 20EXPL: 0CVE-2021-20233 – grub2: Heap out-of-bounds write due to miscalculation of space required for quoting
https://notcve.org/view.php?id=CVE-2021-20233
A flaw was found in grub2 in versions prior to 2.06. Setparam_prefix() in the menu rendering code performs a length calculation on the assumption that expressing a quoted single quote will require 3 characters, while it actually requires 4 characters which allows an attacker to corrupt memory by one byte for each quote in the input. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. Se encontró un fallo en grub2 en versiones anteriores a 2.06. La función Setparam_prefix() en el código de renderización del menú lleva a cabo un cálculo de longitud asumiendo que expresar una comilla simple entre comillas requerirá 3 caracteres, mientras que actualmente requiere 4 caracteres, lo que permite a un atacante corromper la memoria por un byte para cada comilla en la entrada. • https://bugzilla.redhat.com/show_bug.cgi?id=1926263 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ZWZ36QK4IKU6MWDWNOOWKPH3WXZBHT2R https://security.gentoo.org/glsa/202104-05 https://security.netapp.com/advisory/ntap-20220325-0001 https://access.redhat.com/security/cve/CVE-2021-20233 • CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2020-35518
When binding against a DN during authentication, the reply from 389-ds-base will be different whether the DN exists or not. This can be used by an unauthenticated attacker to check the existence of an entry in the LDAP database. Cuando se vincula con un DN durante la autenticación, la respuesta de 389-ds-base será diferente si el DN se presenta o no. Esto puede ser usado por un atacante no autenticado para comprobar la existencia de una entrada en la base de datos de LDAP. • https://bugzilla.redhat.com/show_bug.cgi?id=1905565 https://github.com/389ds/389-ds-base/commit/b6aae4d8e7c8a6ddd21646f94fef1bf7f22c3f32 https://github.com/389ds/389-ds-base/commit/cc0f69283abc082488824702dae485b8eae938bc https://github.com/389ds/389-ds-base/issues/4480 https://access.redhat.com/security/cve/CVE-2020-35518 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-203: Observable Discrepancy •
