In LoadPartitionTable of gpt.cc, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege when inserting a malicious USB device, with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android-8.1 Android-9 Android-10 Android-8.0Android ID: A-152874864 En la función LoadPartitionTable del archivo gpt.cc, se presenta una posible escritura fuera de límites debido a una falta comprobación de límites.

Apache HTTP Server versions 2.4.20 to 2.4.43. A specially crafted value for the 'Cache-Digest' header in a HTTP/2 request would result in a crash when the server actually tries to HTTP/2 PUSH a resource afterwards. Configuring the HTTP/2 feature via "H2Push off" will mitigate this vulnerability for unpatched servers. Apache HTTP Server versiones 2.4.20 hasta 2.4.43.. Un valor especialmente diseñado para el encabezado "Cache-Digest" en una petición HTTP/2 resultaría en un bloqueo cuando el servidor realmente intenta un PUSH HTTP/2 un recurso mas tarde. • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00068.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00071.html http://lists.opensuse.org/opensuse-security-announce/2020-10/msg00081.html http://packetstormsecurity.com/files/160392/Apache-2.4.43-mod_http2-Memory-Corruption.html https://httpd.apache.org/security/vulnerabilities_24.html#CVE-2020-9490 https://lists.apache.org/thread.html/r06f0d87ebb6d59ed8379633f36f72f5b1f79cadfda72ede0830b42cf%40%3Ccvs.httpd.apache.org%3E https://lists& • CWE-400: Uncontrolled Resource Consumption CWE-444: Inconsistent Interpretation of HTTP Requests ('HTTP Request/Response Smuggling') •
CVSS: 6.4EPSS: 0%CPEs: 32EXPL: 0CVE-2020-15705 – GRUB2: avoid loading unsigned kernels when GRUB is booted directly under secureboot without shim
https://notcve.org/view.php?id=CVE-2020-15705
GRUB2 fails to validate kernel signature when booted directly without shim, allowing secure boot to be bypassed. This only affects systems where the kernel signing certificate has been imported directly into the secure boot database and the GRUB image is booted directly without the use of shim. This issue affects GRUB2 version 2.04 and prior versions. GRUB2 presenta un fallo al comprobar la firma del kernel cuando se inicia directamente sin cuña, permitiendo que el arranque seguro sea omitido. Esto solo afecta a los sistemas en los que el certificado de firma del kernel ha sido importado directamente a la base de datos de arranque seguro y la imagen de GRUB es iniciada directamente sin el uso de cuña. • http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00067.html http://lists.opensuse.org/opensuse-security-announce/2020-08/msg00069.html http://ubuntu.com/security/notices/USN-4432-1 http://www.openwall.com/lists/oss-security/2020/07/29/3 http://www.openwall.com/lists/oss-security/2021/03/02/3 http://www.openwall.com/lists/oss-security/2021/09/17/2 http://www.openwall.com/lists/oss-security/2021/09/17/4 http://www.openwall.com/lists/oss-security&#x • CWE-347: Improper Verification of Cryptographic Signature CWE-440: Expected Behavior Violation •
