https://notcve.org/view.php?id=CVE-2020-16166
The Linux kernel through 5.7.11 allows remote attackers to make observations that help to obtain sensitive information about the internal state of the network RNG, aka CID-f227e3ec3b5c. This is related to drivers/char/random.c and kernel/time/timer.c. El kernel de Linux versiones hasta 5.7.11, permite a atacantes remotos realizar observaciones que ayudan a obtener información confidencial sobre el estado interno de la red RNG, también se conoce como CID-f227e3ec3b5c. Esto está relacionado con los archivos drivers/char/random.c y kernel/time/timer.c A flaw was found in the Linux kernel. The generation of the device ID from the network RNG internal state is predictable. • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00009.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00047.html https://arxiv.org/pdf/2012.07432.pdf https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f227e3ec3b5cad859ad15666874405e8c1bbc1d4 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=c51f8f88d705e06bd696d7510aff22b33eb8e638 https://github.com/torvalds/linux/commit/f227e3ec3b5cad859ad15666874405e8c1bbc1d4 https://lists.debian& • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-330: Use of Insufficiently Random Values •
CVSS: 6.4EPSS: 0%CPEs: 33EXPL: 1CVE-2020-15707 – GRUB2 contained integer overflows when handling the initrd command, leading to a heap-based buffer overflow.
https://notcve.org/view.php?id=CVE-2020-15707
Integer overflows were discovered in the functions grub_cmd_initrd and grub_initrd_init in the efilinux component of GRUB2, as shipped in Debian, Red Hat, and Ubuntu (the functionality is not included in GRUB2 upstream), leading to a heap-based buffer overflow. These could be triggered by an extremely large number of arguments to the initrd command on 32-bit architectures, or a crafted filesystem with very large files on any architecture. An attacker could use this to execute arbitrary code and bypass UEFI Secure Boot restrictions. This issue affects GRUB2 version 2.04 and prior versions. Se detectaron desbordamientos de enteros en las funciones grub_cmd_initrd y grub_initrd_init en el componente efilinux de GRUB2, como se incluye en Debian, Red Hat y Ubuntu (la funcionalidad no está incluida aguas arriba de GRUB2), conllevando a un desbordamiento del búfer en la región heap de la memoria. • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00016.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00017.html http://ubuntu.com/security/notices/USN-4432-1 http://www.openwall.com/lists/oss-security/2020/07/29/3 https://access.redhat.com/security/vulnerabilities/grub2bootloader https://lists.gnu.org/archive/html/grub-devel/2020-07/msg00034.html https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/ADV200011 https://security.gentoo.org/ • CWE-190: Integer Overflow or Wraparound CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Optimizer). Supported versions that are affected are 8.0.20 and prior. Easily exploitable vulnerability allows high privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server.

https://notcve.org/view.php?id=CVE-2020-15778
scp in OpenSSH through 8.3p1 allows command injection in the scp.c toremote function, as demonstrated by backtick characters in the destination argument. NOTE: the vendor reportedly has stated that they intentionally omit validation of "anomalous argument transfers" because that could "stand a great chance of breaking existing workflows." ** EN DISPUTA ** scp en OpenSSH versiones hasta 8.3p1 permite una inyección de comandos en la función toremote de scp.c, como lo demuestran los caracteres backtick en el argumento de destino. NOTA: según se informa, el proveedor ha declarado que omite intencionadamente la validación de las "transferencias de argumentos anómalos" porque eso podría "tener grandes posibilidades de romper los flujos de trabajo existentes" A flaw was found in the scp program shipped with the openssh-clients package. An attacker having the ability to scp files to a remote server, could execute arbitrary commands on the remote server by including the command as a part of the filename being copied on the server. This command is run with the permissions of user with which the files were copied on the remote server. • https://github.com/cpandya2909/CVE-2020-15778 https://github.com/Neko-chanQwQ/CVE-2020-15778-Exploit https://github.com/Evan-Zhangyf/CVE-2020-15778 https://access.redhat.com/errata/RHSA-2024:3166 https://news.ycombinator.com/item?id=25005567 https://security.gentoo.org/glsa/202212-06 https://security.netapp.com/advisory/ntap-20200731-0007 https://www.openssh.com/security.html https://access.redhat.com/security/cve/CVE-2020-15778 https://bugzilla.redhat.com/show_bug.cgi?id&# • CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection') CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') •

Vulnerability in the Java SE product of Oracle Java SE (component: JavaFX). The supported version that is affected is Java SE: 8u251. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Java SE, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Java SE. • https://security.gentoo.org/glsa/202209-15 https://security.netapp.com/advisory/ntap-20200717-0005 https://www.oracle.com/security-alerts/cpujul2020.html https://www.zerodayinitiative.com/advisories/ZDI-20-897 •
