https://notcve.org/view.php?id=CVE-2024-6387
01 Jul 2024 — A security regression (CVE-2006-5051) was discovered in OpenSSH's server (sshd). There is a race condition which can lead sshd to handle some signals in an unsafe manner. An unauthenticated, remote attacker may be able to trigger it by failing to authenticate within a set time period. Se encontró una condición de ejecución del controlador de señales en el servidor de OpenSSH (sshd), donde un cliente no se autentica dentro de los segundos de LoginGraceTime (120 de forma predeterminada, 600 en versiones anter... • https://packetstorm.news/files/id/179290 • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-364: Signal Handler Race Condition •
CVSS: 6.8EPSS: 0%CPEs: 14EXPL: 0CVE-2023-6660 – NFS client data corruption and kernel memory disclosure
https://notcve.org/view.php?id=CVE-2023-6660
13 Dec 2023 — When a program running on an affected system appends data to a file via an NFS client mount, the bug can cause the NFS client to fail to copy in the data to be written but proceed as though the copy operation had succeeded. This means that the data to be written is instead replaced with whatever data had been in the packet buffer previously. Thus, an unprivileged user with access to an affected system may abuse the bug to trigger disclosure of sensitive information. In particular, the leak is limited to dat... • https://security.freebsd.org/advisories/FreeBSD-SA-23:18.nfsclient.asc •

13 Dec 2023 — In versions of FreeBSD 14.0-RELEASE before 14-RELEASE-p2, FreeBSD 13.2-RELEASE before 13.2-RELEASE-p7 and FreeBSD 12.4-RELEASE before 12.4-RELEASE-p9, the pf(4) packet filter incorrectly validates TCP sequence numbers. This could allow a malicious actor to execute a denial-of-service attack against hosts behind the firewall. En las versiones de FreeBSD 14.0-RELEASE anteriores a 14-RELEASE-p2, FreeBSD 13.2-RELEASE anteriores a 13.2-RELEASE-p7 y FreeBSD 12.4-RELEASE anteriores a 12.4-RELEASE-p9, el filtro de ... • https://security.freebsd.org/advisories/FreeBSD-SA-23:17.pf.asc •

14 Mar 2020 — grub2-bhyve, as used in FreeBSD bhyve before revision 525916 2020-02-12, does not validate the address provided as part of a memrw command (read_* or write_*) by a guest through a grub2.cfg file. This allows an untrusted guest to perform arbitrary read or write operations in the context of the grub-bhyve process, resulting in code execution as root on the host OS. grub2-bhyve, como es usado en FreeBSD bhyve anterior a revisión 525916 12-02-2020, no comprueba la dirección proporcionada como parte de un coman... • https://svnweb.freebsd.org/ports?view=revision&revision=525916 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
