A flaw was found in ImageMagick in MagickCore/visual-effects.c. An attacker who submits a crafted file that is processed by ImageMagick could trigger undefined behavior in the form of math division by zero. The highest threat from this vulnerability is to system availability. Se encontró un fallo en ImageMagick en el archivo MagickCore/visual-effects.c. Un atacante que envía un archivo diseñado que es procesado por ImageMagick podría desencadenar un comportamiento indefinido en el formulario de división matemática por cero. • https://bugzilla.redhat.com/show_bug.cgi?id=1928959 https://github.com/ImageMagick/ImageMagick/pull/3194 https://lists.debian.org/debian-lts-announce/2021/03/msg00030.html https://lists.debian.org/debian-lts-announce/2023/05/msg00020.html • CWE-369: Divide By Zero •

CVSS: 7.6EPSS: 0%CPEs: 20EXPL: 0CVE-2020-25647 – grub2: Out-of-bounds write in grub_usb_device_initialize()
https://notcve.org/view.php?id=CVE-2020-25647
A flaw was found in grub2 in versions prior to 2.06. During USB device initialization, descriptors are read with very little bounds checking and assumes the USB device is providing sane values. If properly exploited, an attacker could trigger memory corruption leading to arbitrary code execution allowing a bypass of the Secure Boot mechanism. 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. • https://bugzilla.redhat.com/show_bug.cgi?id=1886936 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-2020-25647 • CWE-787: Out-of-bounds Write •
