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 •
CVSS: 6.0EPSS: 0%CPEs: 13EXPL: 0CVE-2020-14310 – grub2: Integer overflow read_section_as_string may lead to heap-based buffer overflow
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 •

https://notcve.org/view.php?id=CVE-2020-15863
hw/net/xgmac.c in the XGMAC Ethernet controller in QEMU before 07-20-2020 has a buffer overflow. This occurs during packet transmission and affects the highbank and midway emulated machines. A guest user or process could use this flaw to crash the QEMU process on the host, resulting in a denial of service or potential privileged code execution. This was fixed in commit 5519724a13664b43e225ca05351c60b4468e4555. El archivo hw/net/xgmac.c en el controlador Ethernet XGMAC en QEMU antes del 20/07/2020, presenta un desbordamiento de búfer. • http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00024.html http://www.openwall.com/lists/oss-security/2020/07/22/1 https://git.qemu.org/?p=qemu.git%3Ba=commitdiff%3Bh=5519724a13664b43e225ca05351c60b4468e4555 https://lists.nongnu.org/archive/html/qemu-devel/2020-07/msg03497.html https://lists.nongnu.org/archive/html/qemu-devel/2020-07/msg05745.html https://security.gentoo.org/glsa/202208-27 https://usn.ubuntu.com/4467-1 https://www.debian.org/security/2020/dsa-47 • CWE-787: Out-of-bounds Write •
CVSS: 3.5EPSS: 0%CPEs: 7EXPL: 0CVE-2020-15103 – Integer Overflow in FreeRDP
https://notcve.org/view.php?id=CVE-2020-15103
In FreeRDP less than or equal to 2.1.2, an integer overflow exists due to missing input sanitation in rdpegfx channel. All FreeRDP clients are affected. The input rectangles from the server are not checked against local surface coordinates and blindly accepted. A malicious server can send data that will crash the client later on (invalid length arguments to a `memcpy`) This has been fixed in 2.2.0. As a workaround, stop using command line arguments /gfx, /gfx-h264 and /network:auto En FreeRDP versiones anteriores o igual a 2.1.2, se presenta un desbordamiento de enteros debido a una falta de saneamiento de entrada en el canal rdpegfx. • http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00010.html https://github.com/FreeRDP/FreeRDP/blob/616af2d5b86dc24c7b3e89870dbcffd841d9a535/ChangeLog#L4 https://github.com/FreeRDP/FreeRDP/pull/6382 https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-4r38-6hq7-j3j9 https://lists.debian.org/debian-lts-announce/2023/10/msg00008.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6Y35HBHG2INICLSGCIKNAR7GCXEHQACQ https://lists.fedoraproject.org/archives/list&#x • CWE-122: Heap-based Buffer Overflow CWE-190: Integer Overflow or Wraparound CWE-680: Integer Overflow to Buffer Overflow •
