CVE-2019-19579
https://notcve.org/view.php?id=CVE-2019-19579
An issue was discovered in Xen through 4.12.x allowing attackers to gain host OS privileges via DMA in a situation where an untrusted domain has access to a physical device (and assignable-add is not used), because of an incomplete fix for CVE-2019-18424. XSA-302 relies on the use of libxl's "assignable-add" feature to prepare devices to be assigned to untrusted guests. Unfortunately, this is not considered a strictly required step for device assignment. The PCI passthrough documentation on the wiki describes alternate ways of preparing devices for assignment, and libvirt uses its own ways as well. Hosts where these "alternate" methods are used will still leave the system in a vulnerable state after the device comes back from a guest. • http://lists.opensuse.org/opensuse-security-announce/2020-01/msg00011.html http://www.openwall.com/lists/oss-security/2019/12/05/7 http://xenbits.xen.org/xsa/advisory-306.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/RJYT5FNGM7JSVHHW6B22TSAATBOAPFPD https://seclists.org/bugtraq/2020/Jan/21 https://www.debian.org/security/2020/dsa-4602 https://www.openwall.com/lists/oss-security/2019/11/26/2 https://xenbits.xen.org/xsa/advisory-30 • CWE-20: Improper Input Validation •
CVE-2019-18609 – librabbitmq: integer overflow in amqp_handle_input in amqp_connection.c leads to heap-based buffer overflow
https://notcve.org/view.php?id=CVE-2019-18609
An issue was discovered in amqp_handle_input in amqp_connection.c in rabbitmq-c 0.9.0. There is an integer overflow that leads to heap memory corruption in the handling of CONNECTION_STATE_HEADER. A rogue server could return a malicious frame header that leads to a smaller target_size value than needed. This condition is then carried on to a memcpy function that copies too much data into a heap buffer. Se detectó un problema en la función amqp_handle_input en el archivo amqp_connection.c en rabbitmq-c versión 0.9.0. • https://github.com/alanxz/rabbitmq-c/blob/master/ChangeLog.md https://github.com/alanxz/rabbitmq-c/commit/fc85be7123050b91b054e45b91c78d3241a5047a https://lists.debian.org/debian-lts-announce/2019/12/msg00004.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WA7CPNVYMF6OQNIYNLWUY6U2GTKFOKH3 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/XQER6XTKYMHNQR7QTHW7DJAH645WQROU https://news.ycombinator.com/item?id=21681976 https://security.gentoo.or • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
CVE-2019-14901 – kernel: heap overflow in marvell/mwifiex/tdls.c
https://notcve.org/view.php?id=CVE-2019-14901
A heap overflow flaw was found in the Linux kernel, all versions 3.x.x and 4.x.x before 4.18.0, in Marvell WiFi chip driver. The vulnerability allows a remote attacker to cause a system crash, resulting in a denial of service, or execute arbitrary code. The highest threat with this vulnerability is with the availability of the system. If code execution occurs, the code will run with the permissions of root. This will affect both confidentiality and integrity of files on the system. • http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00029.html http://packetstormsecurity.com/files/155879/Kernel-Live-Patch-Security-Notice-LSN-0061-1.html http://packetstormsecurity.com/files/156185/Kernel-Live-Patch-Security-Notice-LSN-0062-1.html https://access.redhat.com/errata/RHSA-2020:0204 https://access.redhat.com/errata/RHSA-2020:0328 https://access.redhat.com/errata/RHSA-2020:0339 https://access.redhat.com/errata/RHSA-2020:0374 https://access.redhat.com/errata/RHSA- • CWE-122: Heap-based Buffer Overflow CWE-400: Uncontrolled Resource Consumption CWE-787: Out-of-bounds Write •
CVE-2019-14895 – kernel: heap-based buffer overflow in mwifiex_process_country_ie() function in drivers/net/wireless/marvell/mwifiex/sta_ioctl.c
https://notcve.org/view.php?id=CVE-2019-14895
A heap-based buffer overflow was discovered in the Linux kernel, all versions 3.x.x and 4.x.x before 4.18.0, in Marvell WiFi chip driver. The flaw could occur when the station attempts a connection negotiation during the handling of the remote devices country settings. This could allow the remote device to cause a denial of service (system crash) or possibly execute arbitrary code. Se detectó un desbordamiento de búfer en la región heap de la memoria en el kernel de Linux, todas las versiones 3.x.x y versiones 4.x.x anteriores a 4.18.0, en el controlador del chip WiFi de Marvell. El fallo podría presentarse cuando la estación intenta una negociación de conexión durante el manejo de la configuración country de dispositivos remotos. • http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00029.html http://packetstormsecurity.com/files/155879/Kernel-Live-Patch-Security-Notice-LSN-0061-1.html http://packetstormsecurity.com/files/156185/Kernel-Live-Patch-Security-Notice-LSN-0062-1.html https://access.redhat.com/errata/RHSA-2020:0328 https://access.redhat.com/errata/RHSA-2020:0339 https://access.redhat.com/errata/RHSA-2020:0374 https://access.redhat.com/errata/RHSA-2020:0375 https://access.redhat.com/errata/RHSA- • CWE-122: Heap-based Buffer Overflow CWE-787: Out-of-bounds Write •
CVE-2019-18660 – kernel: powerpc: incomplete Spectre-RSB mitigation leads to information exposure
https://notcve.org/view.php?id=CVE-2019-18660
The Linux kernel before 5.4.1 on powerpc allows Information Exposure because the Spectre-RSB mitigation is not in place for all applicable CPUs, aka CID-39e72bf96f58. This is related to arch/powerpc/kernel/entry_64.S and arch/powerpc/kernel/security.c. El kernel de Linux anterior a la versión 5.4.1 en powerpc permite la exposición de información porque la mitigación Spectre-RSB no está implementada para todas las CPU aplicables, también conocido como CID-39e72bf96f58. Esto está relacionado con arch / powerpc / kernel / entry_64.S y arch / powerpc / kernel / security.c. A flaw was found in the way the Linux kernel implemented a software flush of the Count Cache (indirect branch cache) and Link (Return Address) Stack on the PowerPC platform. • http://lists.opensuse.org/opensuse-security-announce/2019-12/msg00029.html http://packetstormsecurity.com/files/155890/Slackware-Security-Advisory-Slackware-14.2-kernel-Updates.html http://www.openwall.com/lists/oss-security/2019/11/27/1 https://access.redhat.com/errata/RHSA-2020:0174 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.4.1 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=39e72bf96f5847ba87cc5bd7a3ce0fed813dc9ad https://lists.fedoraproject.org& • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
