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') •
CVSS: 6.5EPSS: 0%CPEs: 12EXPL: 0CVE-2020-10756 – QEMU SLiRP Networking Out-Of-Bounds Read Information Disclosure Vulnerability
https://notcve.org/view.php?id=CVE-2020-10756
An out-of-bounds read vulnerability was found in the SLiRP networking implementation of the QEMU emulator. This flaw occurs in the icmp6_send_echoreply() routine while replying to an ICMP echo request, also known as ping. This flaw allows a malicious guest to leak the contents of the host memory, resulting in possible information disclosure. This flaw affects versions of libslirp before 4.3.1. Se encontró una vulnerabilidad de lectura fuera de límites en la implementación de red SLiRP del emulador QEMU. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00035.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00040.html https://bugzilla.redhat.com/show_bug.cgi?id=1835986 https://lists.debian.org/debian-lts-announce/2020/07/msg00020.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/JYTZ32P67PZER6P7TW6FQK3SZRKQLVEI https://security.netapp.com/advisory/ntap-20201001-0001 https://usn.ubuntu.com/4437-1 https://usn.ubuntu.com/ • CWE-125: Out-of-bounds Read •

https://notcve.org/view.php?id=CVE-2020-4067
In coturn before version 4.5.1.3, there is an issue whereby STUN/TURN response buffer is not initialized properly. There is a leak of information between different client connections. One client (an attacker) could use their connection to intelligently query coturn to get interesting bytes in the padding bytes from the connection of another client. This has been fixed in 4.5.1.3. En coturn anterior a la versión 4.5.1.3, se presenta un problema por el cual el búfer de respuesta STUN/TURN no se inicializa apropiadamente. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00010.html https://github.com/coturn/coturn/blob/aab60340b201d55c007bcdc853230f47aa2dfdf1/ChangeLog#L15 https://github.com/coturn/coturn/issues/583 https://github.com/coturn/coturn/security/advisories/GHSA-c8r8-8vp5-6gcm https://lists.debian.org/debian-lts-announce/2020/07/msg00002.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/5G35UBNSRLL6SYRTODYTMBJ65TLQILUM https://lists.fedoraproject.org/archives/list/p • CWE-665: Improper Initialization •

Mutt before 1.14.4 and NeoMutt before 2020-06-19 have a STARTTLS buffering issue that affects IMAP, SMTP, and POP3. When a server sends a "begin TLS" response, the client reads additional data (e.g., from a man-in-the-middle attacker) and evaluates it in a TLS context, aka "response injection."
