CVSS: 5.5EPSS: 0%CPEs: 13EXPL: 0CVE-2020-14314 – kernel: buffer uses out of index in ext3/4 filesystem
https://notcve.org/view.php?id=CVE-2020-14314
A memory out-of-bounds read flaw was found in the Linux kernel before 5.9-rc2 with the ext3/ext4 file system, in the way it accesses a directory with broken indexing. This flaw allows a local user to crash the system if the directory exists. The highest threat from this vulnerability is to system availability. Se encontró un fallo de lectura de memoria fuera de límites en el kernel de Linux versiones anteriores a 5.9-rc2, con el sistema de archivos ext3/ext4, en la manera en que accede a un directorio con indexación rota. Este fallo permite a un usuario local bloquear el sistema si el directorio existe. • https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-14314 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=5872331b3d91820e14716632ebb56b1399b34fe1 https://lists.debian.org/debian-lts-announce/2020/09/msg00025.html https://lists.debian.org/debian-lts-announce/2020/10/msg00032.html https://lists.debian.org/debian-lts-announce/2020/10/msg00034.html https://lore.kernel.org/linux-ext4/f53e246b-647c-64bb-16ec-135383c70ad7%40redhat.com/T/#u https://usn.ubuntu. • CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2020-25285
A race condition between hugetlb sysctl handlers in mm/hugetlb.c in the Linux kernel before 5.8.8 could be used by local attackers to corrupt memory, cause a NULL pointer dereference, or possibly have unspecified other impact, aka CID-17743798d812. Una condición de carrera entre los manejadores hugetlb sysctl en el archivo mm/hugetlb.c en el kernel de Linux versiones anteriores a 5.8.8, podría ser usada por atacantes locales para corromper la memoria, causar una desreferencia del puntero NULL o posiblemente tener otro impacto no especificado, también se conoce como CID-17743798d812 A flaw was found in the Linux kernels sysctl handling code for hugepages management.

CVSS: 3.8EPSS: 0%CPEs: 1EXPL: 0CVE-2014-1420 – Insecure temp file usage in Ubuntu UI toolkit
https://notcve.org/view.php?id=CVE-2014-1420
On desktop, Ubuntu UI Toolkit's StateSaver would serialise data on tmp/ files which an attacker could use to expose potentially sensitive data. StateSaver would also open files without the O_EXCL flag. An attacker could exploit this to launch a symlink attack, though this is partially mitigated by symlink and hardlink restrictions in Ubuntu. Fixed in 1.1.1188+14.10.20140813.4-0ubuntu1. En escritorio, StateSaver de Ubuntu UI Toolkit serializaría datos en archivos tmp/ que un atacante podría usar para exponer datos potencialmente confidenciales. • http://bazaar.launchpad.net/~ubuntu-sdk-team/ubuntu-ui-toolkit/staging/revision/1182 https://launchpad.net/bugs/1348241 • CWE-59: Improper Link Resolution Before File Access ('Link Following') CWE-502: Deserialization of Untrusted Data •
