https://notcve.org/view.php?id=CVE-2019-18683
An issue was discovered in drivers/media/platform/vivid in the Linux kernel through 5.3.8. It is exploitable for privilege escalation on some Linux distributions where local users have /dev/video0 access, but only if the driver happens to be loaded. There are multiple race conditions during streaming stopping in this driver (part of the V4L2 subsystem). These issues are caused by wrong mutex locking in vivid_stop_generating_vid_cap(), vivid_stop_generating_vid_out(), sdr_cap_stop_streaming(), and the corresponding kthreads. At least one of these race conditions leads to a use-after-free. • https://github.com/sanjana123-cloud/CVE-2019-18683 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/2019/11/05/1 https://lists.debian.org/debian-lts-announce/2020/03/msg00001.html https://lore.kernel.org/lkml/20191103221719.27118-1-alex.popov%40linux.com https://seclists.org/bugtraq/2020/Jan/10 https://security.net • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •
CVSS: 8.1EPSS: 0%CPEs: 13EXPL: 2CVE-2019-17498 – libssh2: integer overflow in SSH_MSG_DISCONNECT logic in packet.c
https://notcve.org/view.php?id=CVE-2019-17498
In libssh2 v1.9.0 and earlier versions, the SSH_MSG_DISCONNECT logic in packet.c has an integer overflow in a bounds check, enabling an attacker to specify an arbitrary (out-of-bounds) offset for a subsequent memory read. A crafted SSH server may be able to disclose sensitive information or cause a denial of service condition on the client system when a user connects to the server. En libssh2 versión v1.9.0 y anteriores, la lógica de la función SSH_MSG_DISCONNECT en el archivo packet.c presenta un desbordamiento de enteros en una comprobación de límites, lo que permite a un atacante especificar un desplazamiento arbitrario (fuera de límites) para una lectura de memoria posterior. Un servidor SSH diseñado puede ser capaz de revelar información confidencial o causar una condición de denegación de servicio en el sistema del cliente cuando un usuario conecta con el servidor. libssh2 version 1.9.0 contains a remotely trigger-able out-of-bounds read, leading to denial of service or potentially to information disclosure. • http://lists.opensuse.org/opensuse-security-announce/2019-11/msg00026.html http://packetstormsecurity.com/files/172835/libssh2-1.9.0-Out-Of-Bounds-Read.html https://blog.semmle.com/libssh2-integer-overflow-CVE-2019-17498 https://github.com/kevinbackhouse/SecurityExploits/tree/8cbdbbe6363510f7d9ceec685373da12e6fc752d/libssh2/out_of_bounds_read_disconnect_CVE-2019-17498 https://github.com/libssh2/libssh2/blob/42d37aa63129a1b2644bf6495198923534322d64/src/packet.c#L480 https://github.com/libssh2/libssh2/commit/dedcbd106f8e52d5586b0205bc7677e4c • CWE-190: Integer Overflow or Wraparound CWE-400: Uncontrolled Resource Consumption •

https://notcve.org/view.php?id=CVE-2019-11068
libxslt through 1.1.33 allows bypass of a protection mechanism because callers of xsltCheckRead and xsltCheckWrite permit access even upon receiving a -1 error code. xsltCheckRead can return -1 for a crafted URL that is not actually invalid and is subsequently loaded. libxslt hasta la versión 1.1.33 permite omitir los mecanismos de protección debido a que los callers xsltCheckRead y xsltCheckWrite permiten acceso incluso después de recibir el código de error -1. xsltCheckRead puede devolver -1 para una URL creada que no es realmente inválida y que se carga posteriormente. • http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00048.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00052.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00053.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00025.html http://lists.opensuse.org/opensuse-security-announce/2019-08/msg00001.html http://www.openwall.com/lists/oss-security/2019/04/22/1 http://www.openwall.com/lists/oss-security/2019/04/23/5 https • CWE-284: Improper Access Control •
CVSS: 5.9EPSS: 1%CPEs: 180EXPL: 0CVE-2019-1559 – 0-byte record padding oracle
https://notcve.org/view.php?id=CVE-2019-1559
If an application encounters a fatal protocol error and then calls SSL_shutdown() twice (once to send a close_notify, and once to receive one) then OpenSSL can respond differently to the calling application if a 0 byte record is received with invalid padding compared to if a 0 byte record is received with an invalid MAC. If the application then behaves differently based on that in a way that is detectable to the remote peer, then this amounts to a padding oracle that could be used to decrypt data. In order for this to be exploitable "non-stitched" ciphersuites must be in use. Stitched ciphersuites are optimised implementations of certain commonly used ciphersuites. Also the application must call SSL_shutdown() twice even if a protocol error has occurred (applications should not do this but some do anyway). • http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00041.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00019.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00046.html http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00047.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00049.html http://lists.opensuse.org/opensuse-security-announce/2019-06/msg00080.html http://www.securityfocus.com/bid/107174 https://access. • CWE-203: Observable Discrepancy CWE-325: Missing Cryptographic Step •
CVSS: 7.5EPSS: 1%CPEs: 6EXPL: 0CVE-2018-5734 – A malformed request can trigger an assertion failure in badcache.c
https://notcve.org/view.php?id=CVE-2018-5734
While handling a particular type of malformed packet BIND erroneously selects a SERVFAIL rcode instead of a FORMERR rcode. If the receiving view has the SERVFAIL cache feature enabled, this can trigger an assertion failure in badcache.c when the request doesn't contain all of the expected information. Affects BIND 9.10.5-S1 to 9.10.5-S4, 9.10.6-S1, 9.10.6-S2. Al gestionar un tipo concreto de paquete mal formado, BIND selecciona erróneamente un rcode SERVFAIL en lugar de un rcode FORMERR. Si la vista que se está recibiendo tiene la característica de caché SERVFAIL habilitada, esto puede desencadenar un fallo de aserción en badcache.c cuando la petición no contiene toda la información esperada. • http://www.securityfocus.com/bid/103189 http://www.securitytracker.com/id/1040438 https://kb.isc.org/docs/aa-01562 https://security.netapp.com/advisory/ntap-20180926-0005 • CWE-617: Reachable Assertion •
