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 •
