CVSS: 6.5EPSS: 0%CPEs: 8EXPL: 0CVE-2020-15652 – Mozilla: Potential leak of redirect targets when loading scripts in a worker
https://notcve.org/view.php?id=CVE-2020-15652
By observing the stack trace for JavaScript errors in web workers, it was possible to leak the result of a cross-origin redirect. This applied only to content that can be parsed as script. This vulnerability affects Firefox < 79, Firefox ESR < 68.11, Firefox ESR < 78.1, Thunderbird < 68.11, and Thunderbird < 78.1. Al observar el seguimiento de la pila de errores de JavaScript en los trabajadores web, fue posible filtrar el resultado de un redireccionamiento de origen cruzado. Esto se aplica solo al contenido que puede ser analizado como script. • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00022.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00032.html https://bugzilla.mozilla.org/show_bug.cgi?id=1634872 https://usn.ubuntu.com/4443-1 https://www.mozilla.org/security/advisories/mfsa2020-30 https://www.mozilla.org/security/advisories/mfsa2020-31 https://www.mozilla.org/security/advisories/mfsa2020-32 https://www.mozill • CWE-209: Generation of Error Message Containing Sensitive Information CWE-346: Origin Validation Error •

https://notcve.org/view.php?id=CVE-2020-15659
Mozilla developers and community members reported memory safety bugs present in Firefox 78 and Firefox ESR 78.0. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 79, Firefox ESR < 68.11, Firefox ESR < 78.1, Thunderbird < 68.11, and Thunderbird < 78.1. Los desarrolladores de Mozilla y los miembros de la comunidad informaron bugs de seguridad de la memoria presentes en Firefox versión 78 y Firefox ESR versión 78.0. Algunos de estos bugs mostraron evidencia de corrupción de la memoria y suponemos que con un suficiente esfuerzo algunos de ellos podrían haberse explotado para ejecutar código arbitrario. • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00022.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00032.html https://bugzilla.mozilla.org/buglist.cgi?bug_id=1550133%2C1633880%2C1643613%2C1644839%2C1645835%2C1646006%2C1646787%2C1649347%2C1650811%2C1651678 https://usn.ubuntu.com/4443-1 https://www.mozilla.org/security/advisories/mfsa2020-30 https://www.mozilla.org/security/advisories/mfsa2020-31 https • CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2020-14311
There is an issue with grub2 before version 2.06 while handling symlink on ext filesystems. A filesystem containing a symbolic link with an inode size of UINT32_MAX causes an arithmetic overflow leading to a zero-sized memory allocation with subsequent heap-based buffer overflow. Se presenta un problema con grub2 versiones anteriores a 2.06, mientras se maneja un symlink en los sistemas de archivos ext. Un sistema de archivos que contiene un enlace simbólico con un tamaño de inode de UINT32_MAX causa un desbordamiento aritmético conllevando a una asignación de memoria de tamaño cero con el posterior desbordamiento del búfer en la región heap de la memoria A flaw was found in grub2 while handling symlink on ext filesystems.

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') •

https://notcve.org/view.php?id=CVE-2020-14310
There is an issue on grub2 before version 2.06 at function read_section_as_string(). It expects a font name to be at max UINT32_MAX - 1 length in bytes but it doesn't verify it before proceed with buffer allocation to read the value from the font value. An attacker may leverage that by crafting a malicious font file which has a name with UINT32_MAX, leading to read_section_as_string() to an arithmetic overflow, zero-sized allocation and further heap-based buffer overflow. Se presenta un problema en grub2 versiones anteriores a 2.06, en la función read_section_as_string(). Se espera que el nombre de la fuente sea una longitud máxima UINT32_MAX - 1 en bytes, pero no lo verifica antes de proceder con la asignación del búfer para leer el valor desde el valor de la fuente. • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00016.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00017.html https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-14310 https://security.gentoo.org/glsa/202104-05 https://usn.ubuntu.com/4432-1 https://access.redhat.com/security/cve/CVE-2020-14310 https://bugzilla.redhat.com/show_bug.cgi?id=1852030 • CWE-122: Heap-based Buffer Overflow CWE-190: Integer Overflow or Wraparound •
