https://notcve.org/view.php?id=CVE-2019-5094
An exploitable code execution vulnerability exists in the quota file functionality of E2fsprogs 1.45.3. A specially crafted ext4 partition can cause an out-of-bounds write on the heap, resulting in code execution. An attacker can corrupt a partition to trigger this vulnerability. Se presenta una vulnerabilidad de ejecución de código explotable en la funcionalidad quota file de E2fsprogs versión 1.45.3. Una partición ext4 especialmente diseñada puede causar una escritura fuera de límites en la pila, resultando en la ejecución de código. • https://lists.debian.org/debian-lts-announce/2019/09/msg00029.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/2AKETJ6BREDUHRWQTV35SPGG5C6H7KSI https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/6DOBCYQKCTTWXBLMUPJ5TX3FY7JNCOKY https://seclists.org/bugtraq/2019/Sep/58 https://security.gentoo.org/glsa/202003-05 https://security.netapp.com/advisory/ntap-20200115-0002 https://talosintelligence.com/vulnerability_reports/TALOS-2019-0887 htt • CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2019-14835
A buffer overflow flaw was found, in versions from 2.6.34 to 5.2.x, in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could use this flaw to increase their privileges on the host. Se encontró un fallo de desbordamiento de búfer, en las versiones desde 2.6.34 hasta 5.2.x, en la manera en que la funcionalidad vhost del kernel de Linux que traduce los búferes virtueue en IOV, registraba los descriptores del búfer durante una migración. Un usuario invitado privilegiado capaz de pasar descriptores con una longitud no válida hacia el host cuando la migración está en marcha, podría usar este fallo para aumentar sus privilegios sobre el host.

CVSS: 4.4EPSS: 0%CPEs: 10EXPL: 1CVE-2019-15031 – kernel: powerpc: local user can read vector registers of other users' processes via an interrupt
https://notcve.org/view.php?id=CVE-2019-15031
In the Linux kernel through 5.2.14 on the powerpc platform, a local user can read vector registers of other users' processes via an interrupt. To exploit the venerability, a local user starts a transaction (via the hardware transactional memory instruction tbegin) and then accesses vector registers. At some point, the vector registers will be corrupted with the values from a different local Linux process, because MSR_TM_ACTIVE is misused in arch/powerpc/kernel/process.c. En el kernel de Linux versiones hasta 5.2.14 en la plataforma powerpc, un usuario local puede leer los registros vectoriales de los procesos de otros usuarios por medio de una interrupción. Para explotar la venerabilidad, un usuario local inicia una transacción (por medio de la instrucción de memoria transaccional de hardware tbegin) y luego accede a los registros vectoriales. • http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00064.html http://lists.opensuse.org/opensuse-security-announce/2019-09/msg00066.html http://www.openwall.com/lists/oss-security/2019/09/10/4 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=a8318c13e79badb92bc6640704a64cc022a6eb97 https://security.netapp.com/advisory/ntap-20191004-0001 https://usn.ubuntu.com/4135-1 https://usn.ubuntu.com/4135-2 https://access.redhat.com/security/cve/CVE-2019 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-662: Improper Synchronization •

https://notcve.org/view.php?id=CVE-2019-16275
hostapd before 2.10 and wpa_supplicant before 2.10 allow an incorrect indication of disconnection in certain situations because source address validation is mishandled. This is a denial of service that should have been prevented by PMF (aka management frame protection). The attacker must send a crafted 802.11 frame from a location that is within the 802.11 communications range. hostapd versiones anteriores a 2.10 y wpa_supplicant versiones anteriores a 2.10, permiten una indicación incorrecta de desconexión en ciertas situaciones porque la comprobación de la dirección de origen es manejada inapropiadamente. Esta es una denegación de servicio que debió haber sido evitada mediante PMF (también se conoce como protección de la trama de administración). El atacante requiere enviar una trama 802.11 diseñada desde una ubicación que este dentro del rango de comunicaciones de 802.11. • http://www.openwall.com/lists/oss-security/2019/09/12/6 https://lists.debian.org/debian-lts-announce/2019/09/msg00017.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/36G4XAZ644DMHBLKOL4FDSPZVIGNQY6U https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/B7NCLOPTZNRRNYODH22BFIDH6YIQWLJD https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/FEGITWRTIWABW54ANEPCEF4ARZLXGSK5 https://lists.fedoraproject.org/archives& • CWE-346: Origin Validation Error •
