CVSS: 8.2EPSS: 0%CPEs: 11EXPL: 0CVE-2019-8308 – flatpak: potential /proc based sandbox escape
https://notcve.org/view.php?id=CVE-2019-8308
Flatpak before 1.0.7, and 1.1.x and 1.2.x before 1.2.3, exposes /proc in the apply_extra script sandbox, which allows attackers to modify a host-side executable file. Flatpak, en versiones anteriores a la 1.0.7 y en versiones 1.1.x y 1.2.x anteriores a la 1.2.3, expone /proc en el sandbox de script apply_extra, lo que permite que los atacantes modifiquen un archivo ejecutable del lado del host. A flaw was found in flatpak. In certain special cases, installing flatpak applications and runtimes system-wide may allow an attacker to escape the flatpak sandbox. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability. • http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00088.html https://access.redhat.com/errata/RHSA-2019:0375 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=922059 https://github.com/flatpak/flatpak/releases/tag/1.0.7 https://github.com/flatpak/flatpak/releases/tag/1.2.3 https://access.redhat.com/security/cve/CVE-2019-8308 https://bugzilla.redhat.com/show_bug.cgi?id=1675070 • CWE-668: Exposure of Resource to Wrong Sphere CWE-672: Operation on a Resource after Expiration or Release •

https://notcve.org/view.php?id=CVE-2019-7665
In elfutils 0.175, a heap-based buffer over-read was discovered in the function elf32_xlatetom in elf32_xlatetom.c in libelf. A crafted ELF input can cause a segmentation fault leading to denial of service (program crash) because ebl_core_note does not reject malformed core file notes. En elfutils 0.175, existe una sobrelectura de búfer basada en memoria dinámica (heap) en la función elf32_xlatetom en elf32_xlatetom.c. Una entrada ELF manipulada puede provocar un fallo de segmentación que conduce a una denegación de servicio (cierre inesperado del programa) debido a que ebl_core_note no rechaza las notas de archivo core mal formadas. • http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00052.html https://access.redhat.com/errata/RHSA-2019:2197 https://access.redhat.com/errata/RHSA-2019:3575 https://lists.debian.org/debian-lts-announce/2019/02/msg00036.html https://lists.debian.org/debian-lts-announce/2021/10/msg00030.html https://sourceware.org/bugzilla/show_bug.cgi?id=24089 https://sourceware.org/ml/elfutils-devel/2019-q1/msg00049.html https://usn.ubuntu.com/4012-1 https://access.redhat.com&#x • CWE-122: Heap-based Buffer Overflow CWE-125: Out-of-bounds Read •
