https://notcve.org/view.php?id=CVE-2021-46790
ntfsck in NTFS-3G through 2021.8.22 has a heap-based buffer overflow involving buffer+512*3-2. NOTE: the upstream position is that ntfsck is deprecated; however, it is shipped by some Linux distributions. ntfsck en NTFS-3G versiones hasta 2021.8.22, presenta un desbordamiento del búfer en la región heap de la memoria que afecta al búfer+512*3-2. NOTA: la posición de la corriente principal es que ntfsck está obsoleto; sin embargo, es incluido en algunas distribuciones de Linux A vulnerability was found in NTFS-3G, specifically in the ntfsck utility. Incorrect validation of NTFS metadata can result in a heap-based buffer overflow when processing a crafted NTFS image file or partition. • http://www.openwall.com/lists/oss-security/2022/05/26/1 https://github.com/tuxera/ntfs-3g/issues/16 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/7JPX6OUCQKZX4PN5DQPVDUFZCOOZUX7Z https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ECDCISL24TYH4CTDFCUVF24WAKRSYF7F https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FAXFYIJWT5SHHRNPOJETM77EIMJ6ZP6I https://lists.fedoraproject.org/archives/list/package-announce • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •

Sinatra before 2.2.0 does not validate that the expanded path matches public_dir when serving static files. Sinatra versiones anteriores a 2.2.0, no comprueba que la ruta expandida coincida con public_dir cuando sirve archivos estáticos A flaw was found in Sinatra when serving static files from the public directory. The requested path is not validated if it is in the public directory, allowing files outside of the public directory to be served. • https://github.com/sinatra/sinatra/pull/1683/commits/462c3ca1db53ed3cfc394cf5948e9c948ad1c10e https://lists.debian.org/debian-lts-announce/2022/10/msg00034.html https://access.redhat.com/security/cve/CVE-2022-29970 https://bugzilla.redhat.com/show_bug.cgi?id=2081096 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') •

https://notcve.org/view.php?id=CVE-2021-4206
A flaw was found in the QXL display device emulation in QEMU. An integer overflow in the cursor_alloc() function can lead to the allocation of a small cursor object followed by a subsequent heap-based buffer overflow. This flaw allows a malicious privileged guest user to crash the QEMU process on the host or potentially execute arbitrary code within the context of the QEMU process. Se ha encontrado un fallo en la emulación del dispositivo de visualización QXL en QEMU. Un desbordamiento de enteros en la función cursor_alloc() puede conllevar a una asignación de un pequeño objeto cursor seguido de un posterior desbordamiento del búfer en la región heap de la memoria. • https://bugzilla.redhat.com/show_bug.cgi?id=2036998 https://lists.debian.org/debian-lts-announce/2022/09/msg00008.html https://security.gentoo.org/glsa/202208-27 https://starlabs.sg/advisories/21-4206 https://www.debian.org/security/2022/dsa-5133 https://access.redhat.com/security/cve/CVE-2021-4206 • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-131: Incorrect Calculation of Buffer Size CWE-190: Integer Overflow or Wraparound •
