CVE-2020-11736 – file-roller: directory traversal via directory symlink pointing outside of the target directory
https://notcve.org/view.php?id=CVE-2020-11736
13 Apr 2020 — fr-archive-libarchive.c in GNOME file-roller through 3.36.1 allows Directory Traversal during extraction because it lacks a check of whether a file's parent is a symlink to a directory outside of the intended extraction location. El archivo fr-archive-libarchive.c en GNOME file-roller versiones hasta 3.36.1, permite un Salto del Directorio durante la extracción porque carece de una comprobación de si el padre de un archivo es un enlace simbólico en un directorio fuera de la ubicación de extracción prevista. • https://gitlab.gnome.org/GNOME/file-roller/-/commit/21dfcdbfe258984db89fb65243a1a888924e45a0 • CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') CWE-59: Improper Link Resolution Before File Access ('Link Following') •
CVE-2020-1730 – libssh: denial of service when handling AES-CTR (or DES) ciphers
https://notcve.org/view.php?id=CVE-2020-1730
09 Apr 2020 — A flaw was found in libssh versions before 0.8.9 and before 0.9.4 in the way it handled AES-CTR (or DES ciphers if enabled) ciphers. The server or client could crash when the connection hasn't been fully initialized and the system tries to cleanup the ciphers when closing the connection. The biggest threat from this vulnerability is system availability.

CVE-2020-11565 – kernel: out-of-bounds write in mpol_parse_str function in mm/mempolicy.c
https://notcve.org/view.php?id=CVE-2020-11565
06 Apr 2020 — An issue was discovered in the Linux kernel through 5.6.2. mpol_parse_str in mm/mempolicy.c has a stack-based out-of-bounds write because an empty nodelist is mishandled during mount option parsing, aka CID-aa9f7d5172fa. NOTE: Someone in the security community disagrees that this is a vulnerability because the issue “is a bug in parsing mount options which can only be specified by a privileged user, so triggering the bug does not grant any powers not already held.” ** EN DISPUTA ** Se detectó un problema en... • https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=aa9f7d5172fac9bf1f09e678c35e287a40a7b7dd • CWE-787: Out-of-bounds Write •

02 Apr 2020 — An issue was discovered in slc_bump in drivers/net/can/slcan.c in the Linux kernel 3.16 through 5.6.2. It allows attackers to read uninitialized can_frame data, potentially containing sensitive information from kernel stack memory, if the configuration lacks CONFIG_INIT_STACK_ALL, aka CID-b9258a2cece4.

CVE-2020-8831 – World writable root owned lock file created in user controllable location
https://notcve.org/view.php?id=CVE-2020-8831
02 Apr 2020 — Apport creates a world writable lock file with root ownership in the world writable /var/lock/apport directory. If the apport/ directory does not exist (this is not uncommon as /var/lock is a tmpfs), it will create the directory, otherwise it will simply continue execution using the existing directory. This allows for a symlink attack if an attacker were to create a symlink at /var/lock/apport, changing apport's lock file location. This file could then be used to escalate privileges, for example.

CVE-2020-8833 – Apport race condition in crash report permissions
https://notcve.org/view.php?id=CVE-2020-8833
02 Apr 2020 — Time-of-check Time-of-use Race Condition vulnerability on crash report ownership change in Apport allows for a possible privilege escalation opportunity. If fs.protected_symlinks is disabled, this can be exploited between the os.open and os.chown calls when the Apport cron script clears out crash files of size 0. A symlink with the same name as the deleted file can then be created upon which chown will be called, changing the file owner to root.
