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 •
