CVSS: 7.5EPSS: 0%CPEs: 41EXPL: 0CVE-2021-3695 – grub2: Crafted PNG grayscale images may lead to out-of-bounds write in heap
https://notcve.org/view.php?id=CVE-2021-3695
A crafted 16-bit grayscale PNG image may lead to a out-of-bounds write in the heap area. An attacker may take advantage of that to cause heap data corruption or eventually arbitrary code execution and circumvent secure boot protections. This issue has a high complexity to be exploited as an attacker needs to perform some triage over the heap layout to achieve signifcant results, also the values written into the memory are repeated three times in a row making difficult to produce valid payloads. This flaw affects grub2 versions prior grub-2.12. Una imagen PNG en escala de grises de 16 bits diseñada puede conllevar a una escritura fuera de límites en el área de la pila. • https://bugzilla.redhat.com/show_bug.cgi?id=1991685 https://security.gentoo.org/glsa/202209-12 https://security.netapp.com/advisory/ntap-20220930-0001 https://access.redhat.com/security/cve/CVE-2021-3695 • CWE-787: Out-of-bounds Write •
CVSS: 7.5EPSS: 0%CPEs: 2EXPL: 0CVE-2022-29244 – npm packing does not respect root-level ignore files in workspaces
https://notcve.org/view.php?id=CVE-2022-29244
npm pack ignores root-level .gitignore and .npmignore file exclusion directives when run in a workspace or with a workspace flag (ie. `--workspaces`, `--workspace=<name>`). Anyone who has run `npm pack` or `npm publish` inside a workspace, as of v7.9.0 and v7.13.0 respectively, may be affected and have published files into the npm registry they did not intend to include. Users should upgrade to the latest, patched version of npm v8.11.0, run: npm i -g npm@latest . Node.js versions v16.15.1, v17.19.1, and v18.3.0 include the patched v8.11.0 version of npm. npm pack ignora las directivas de exclusión de archivos .gitignore y .npmignore a nivel de root cuando es ejecutado en un espacio de trabajo o con un flag de espacio de trabajo (es decir, "--workspaces", "--workspace=(name)"). • https://github.com/nodejs/node/pull/43210 https://github.com/nodejs/node/releases/tag/v16.15.1 https://github.com/nodejs/node/releases/tag/v17.9.1 https://github.com/nodejs/node/releases/tag/v18.3.0 https://github.com/npm/cli/releases/tag/v8.11.0 https://github.com/npm/cli/security/advisories/GHSA-hj9c-8jmm-8c52 https://github.com/npm/cli/tree/latest/workspaces/libnpmpack https://github.com/npm/cli/tree/latest/workspaces/libnpmpublish https://github.com • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-212: Improper Removal of Sensitive Information Before Storage or Transfer •
