CVE-2019-14815 – kernel: heap-overflow in mwifiex_set_wmm_params() function of Marvell WiFi driver leading to DoS
https://notcve.org/view.php?id=CVE-2019-14815
A vulnerability was found in Linux Kernel, where a Heap Overflow was found in mwifiex_set_wmm_params() function of Marvell Wifi Driver. Se encontró una vulnerabilidad en Linux Kernel, donde se encontró un desbordamiento de pila en la función mwifiex_set_wmm_params () del controlador Marvell Wifi. A vulnerability found in the Linux kernel's WMM implementation for Marvell WiFi-based hardware (mwifiex) could lead to a denial of service or allow arbitrary code execution. For this flaw to be executed, the attacker must be both local and privileged. There is no mitigation to this flaw. • https://access.redhat.com/errata/RHSA-2020:0174 https://access.redhat.com/errata/RHSA-2020:0328 https://access.redhat.com/errata/RHSA-2020:0339 https://access.redhat.com/security/cve/cve-2019-14815 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2019-14815 https://github.com/torvalds/linux/commit/7caac62ed598a196d6ddf8d9c121e12e082cac3a https://lists.debian.org/debian-lts-announce/2020/03/msg00001.html https://lore.kernel.org/linux-wireless/20190828020751.13625-1-huangwenabc%40gmail.com https: • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
CVE-2019-14814 – kernel: heap overflow in mwifiex_set_uap_rates() function of Marvell Wifi Driver leading to DoS
https://notcve.org/view.php?id=CVE-2019-14814
There is heap-based buffer overflow in Linux kernel, all versions up to, excluding 5.3, in the marvell wifi chip driver in Linux kernel, that allows local users to cause a denial of service(system crash) or possibly execute arbitrary code. Se presenta un desbordamiento de búfer en la región heap de la memoria en el kernel de Linux, todas las versiones hasta 5.3 (excluyéndola), en el controlador de chip wifi marvell en el kernel de Linux, que permite a usuarios locales causar una denegación de servicio (bloqueo del sistema) o posiblemente ejecutar código arbitrario. A flaw was found in the Linux kernel’s implementation of the Marvell wifi driver, which can allow a local user who has CAP_NET_ADMIN or administrative privileges to possibly cause a Denial Of Service (DOS) by corrupting memory and possible code execution. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00064.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00066.html http://packetstormsecurity.com/files/154951/Kernel-Live-Patch-Security-Notice-LSN-0058-1.html http://packetstormsecurity.com/files/155212/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://www.openwall.com/lists/oss-security/2019/08/28/1 https://access.redhat.com/errata/RHSA-2020:0174 https://access.redhat.com/errata/RHSA-2020:0328 • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
CVE-2019-14816 – kernel: heap overflow in mwifiex_update_vs_ie() function of Marvell WiFi driver
https://notcve.org/view.php?id=CVE-2019-14816
There is heap-based buffer overflow in kernel, all versions up to, excluding 5.3, in the marvell wifi chip driver in Linux kernel, that allows local users to cause a denial of service(system crash) or possibly execute arbitrary code. Se presenta un desbordamiento del búfer en la región heap de la memoria en el kernel, todas las versiones hasta 5.3 (excluyéndola), en el controlador de chip wifi marvell en el kernel de Linux, que permite a usuarios locales causar una denegación de servicio (bloqueo del sistema) o posiblemente ejecutar código arbitrario. A vulnerability was found in the Linux kernel's Marvell WiFi chip driver. Where, while parsing vendor-specific informational attributes, an attacker on the same WiFi physical network segment could cause a system crash, resulting in a denial of service, or potentially execute arbitrary code. This flaw affects the network interface at the most basic level meaning the attacker only needs to affiliate with the same network device as the vulnerable system to create an attack path. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00064.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00066.html http://packetstormsecurity.com/files/154951/Kernel-Live-Patch-Security-Notice-LSN-0058-1.html http://packetstormsecurity.com/files/155212/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://www.openwall.com/lists/oss-security/2019/08/28/1 https://access.redhat.com/errata/RHSA-2020:0174 https://access.redhat.com/errata/RHSA-2020:0204 • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
CVE-2019-9506 – Blutooth BR/EDR specification does not specify sufficient encryption key length and allows an attacker to influence key length negotiation
https://notcve.org/view.php?id=CVE-2019-9506
The Bluetooth BR/EDR specification up to and including version 5.1 permits sufficiently low encryption key length and does not prevent an attacker from influencing the key length negotiation. This allows practical brute-force attacks (aka "KNOB") that can decrypt traffic and inject arbitrary ciphertext without the victim noticing. La especificación de Bluetooth BR/EDR incluyendo versión 5.1, permite una longitud de clave de cifrado suficientemente baja y no impide que un atacante influya en la negociación de longitud de clave. Esto permite ataques prácticos de fuerza bruta (también se conoce como "KNOB") que pueden descifrar el tráfico e inyectar texto cifrado arbitrario sin que la víctima se dé cuenta. A flaw was discovered in the Bluetooth protocol. • http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00036.html http://lists.opensuse.org/opensuse-security-announce/2019-10/msg00037.html http://seclists.org/fulldisclosure/2019/Aug/11 http://seclists.org/fulldisclosure/2019/Aug/13 http://seclists.org/fulldisclosure/2019/Aug/14 http://seclists.org/fulldisclosure/2019/Aug/15 http://www.cs.ox.ac.uk/publications/publication12404-abstract.html http://www.huawei.com/en/psirt/security-advisories/huawei-sa-20190828-01-knob-en https: • CWE-310: Cryptographic Issues CWE-327: Use of a Broken or Risky Cryptographic Algorithm •
CVE-2019-13272 – Linux Kernel Improper Privilege Management Vulnerability
https://notcve.org/view.php?id=CVE-2019-13272
In the Linux kernel before 5.1.17, ptrace_link in kernel/ptrace.c mishandles the recording of the credentials of a process that wants to create a ptrace relationship, which allows local users to obtain root access by leveraging certain scenarios with a parent-child process relationship, where a parent drops privileges and calls execve (potentially allowing control by an attacker). One contributing factor is an object lifetime issue (which can also cause a panic). Another contributing factor is incorrect marking of a ptrace relationship as privileged, which is exploitable through (for example) Polkit's pkexec helper with PTRACE_TRACEME. NOTE: SELinux deny_ptrace might be a usable workaround in some environments. En el kernel de Linux anterior a versión 5.1.17, ptrace_link en el archivo kernel/ptrace.c maneja inapropiadamente la grabación de las credenciales de un proceso que desea crear una relación de ptrace, que permite a los usuarios locales obtener acceso de root aprovechando determinados escenarios con un relación de proceso padre-hijo, donde un padre elimina los privilegios y llama a execve (permitiendo potencialmente el control por parte de un atacante). • https://www.exploit-db.com/exploits/47133 https://www.exploit-db.com/exploits/47163 https://www.exploit-db.com/exploits/50541 https://www.exploit-db.com/exploits/47543 https://github.com/jas502n/CVE-2019-13272 https://github.com/Cyc1eC/CVE-2019-13272 https://github.com/oneoy/CVE-2019-13272 https://github.com/polosec/CVE-2019-13272 https://github.com/MDS1GNAL/ptrace_scope-CVE-2019-13272-privilege-escalation https://github.com/datntsec/CVE-2019-13272 https://github • CWE-271: Privilege Dropping / Lowering Errors •
