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. Fixed in versions 2.20.1-0ubuntu2.23, 2.20.9-0ubuntu7.14, 2.20... • https://bugs.launchpad.net/ubuntu/+source/apport/+bug/1862933 • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •

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.

27 Mar 2020 — In PHP versions 7.3.x below 7.3.16 and 7.4.x below 7.4.4, while using mb_strtolower() function with UTF-32LE encoding, certain invalid strings could cause PHP to overwrite stack-allocated buffer. This could lead to memory corruption, crashes and potentially code execution. En PHP versiones 7.3.x por debajo de 7.3.16 y versiones 7.4.x por debajo de 7.4.4, mientras se usa la función mb_strtolower() con codificación UTF-32LE, determinadas cadenas no comprobadas pueden causar que PHP sobrescriba el búfer asigna... • https://bugs.php.net/bug.php?id=79371 • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •

CVE-2020-7064 – Use-of-uninitialized-value in exif

27 Mar 2020 — In PHP versions 7.2.x below 7.2.9, 7.3.x below 7.3.16 and 7.4.x below 7.4.4, while parsing EXIF data with exif_read_data() function, it is possible for malicious data to cause PHP to read one byte of uninitialized memory. This could potentially lead to information disclosure or crash.

CVE-2020-10942 – kernel: vhost-net: stack overflow in get_raw_socket while checking sk_family field
https://notcve.org/view.php?id=CVE-2020-10942
24 Mar 2020 — In the Linux kernel before 5.5.8, get_raw_socket in drivers/vhost/net.c lacks validation of an sk_family field, which might allow attackers to trigger kernel stack corruption via crafted system calls. En el kernel de Linux versiones anteriores a 5.5.8, la función get_raw_socket en el archivo drivers/vhost/net.c carece de una comprobación de un campo sk_family, que podría permitir a atacantes desencadenar una corrupción de pila del kernel por medio de llamadas de sistema diseñadas.

CVE-2020-7062 – Null Pointer Dereference in PHP Session Upload Progress
