CVSS: 7.8EPSS: 0%CPEs: 24EXPL: 4CVE-2018-8897 – Microsoft Windows - 'POP/MOV SS' Privilege Escalation
https://notcve.org/view.php?id=CVE-2018-8897
A statement in the System Programming Guide of the Intel 64 and IA-32 Architectures Software Developer's Manual (SDM) was mishandled in the development of some or all operating-system kernels, resulting in unexpected behavior for #DB exceptions that are deferred by MOV SS or POP SS, as demonstrated by (for example) privilege escalation in Windows, macOS, some Xen configurations, or FreeBSD, or a Linux kernel crash. The MOV to SS and POP SS instructions inhibit interrupts (including NMIs), data breakpoints, and single step trap exceptions until the instruction boundary following the next instruction (SDM Vol. 3A; section 6.8.3). (The inhibited data breakpoints are those on memory accessed by the MOV to SS or POP to SS instruction itself.) Note that debug exceptions are not inhibited by the interrupt enable (EFLAGS.IF) system flag (SDM Vol. 3A; section 2.3). If the instruction following the MOV to SS or POP to SS instruction is an instruction like SYSCALL, SYSENTER, INT 3, etc. that transfers control to the operating system at CPL < 3, the debug exception is delivered after the transfer to CPL < 3 is complete. • https://www.exploit-db.com/exploits/44697 https://www.exploit-db.com/exploits/45024 https://github.com/can1357/CVE-2018-8897 https://github.com/nmulasmajic/CVE-2018-8897 http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=d8ba61ba58c88d5207c1ba2f7d9a2280e7d03be9 http://openwall.com/lists/oss-security/2018/05/08/1 http://openwall.com/lists/oss-security/2018/05/08/4 http://www.huawei.com/en/psirt/security-advisories/huawei-sa-20190921-01-debug-en http: • CWE-250: Execution with Unnecessary Privileges CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •

It was found that samba before 4.4.16, 4.5.x before 4.5.14, and 4.6.x before 4.6.8 did not enforce "SMB signing" when certain configuration options were enabled. A remote attacker could launch a man-in-the-middle attack and retrieve information in plain-text.

https://notcve.org/view.php?id=CVE-2017-12163
An information leak flaw was found in the way SMB1 protocol was implemented by Samba before 4.4.16, 4.5.x before 4.5.14, and 4.6.x before 4.6.8. A malicious client could use this flaw to dump server memory contents to a file on the samba share or to a shared printer, though the exact area of server memory cannot be controlled by the attacker. Se ha descubierto una vulnerabilidad de fuga de información en la manera en la que Samba, en versiones anteriores a la 4.4.16, versiones 4.5.x anteriores a la 4.5.14 y versiones 4.6.x anteriores a la 4.6.8, implementó el protocolo SMB1. Un cliente malicioso podría utilizar esta vulnerabilidad para volcar los contenidos de la memoria del servidor en un archivo en el almacenamiento de samba o en una impresora compartida, aunque el atacante no pueda controlar el área exacta de memoria del servidor.

https://notcve.org/view.php?id=CVE-2017-10664
qemu-nbd in QEMU (aka Quick Emulator) does not ignore SIGPIPE, which allows remote attackers to cause a denial of service (daemon crash) by disconnecting during a server-to-client reply attempt. qemu-nbd en QEMU (Quick Emulator) no ignora la señal SIGPIPE, lo que permite a atacantes remotos provocar una denegación de servicio desconectando el proceso durante un intento de respuesta de servidor a cliente. Quick Emulator (QEMU) built with the Network Block Device (NBD) Server support is vulnerable to a crash via a SIGPIPE signal. The crash can occur if a client aborts a connection due to any failure during negotiation or read operation. A remote user/process could use this flaw to crash the qemu-nbd server resulting in a Denial of Service (DoS). • http://www.debian.org/security/2017/dsa-3920 http://www.openwall.com/lists/oss-security/2017/06/29/1 http://www.securityfocus.com/bid/99513 https://access.redhat.com/errata/RHSA-2017:2390 https://access.redhat.com/errata/RHSA-2017:2445 https://access.redhat.com/errata/RHSA-2017:3466 https://access.redhat.com/errata/RHSA-2017:3470 https://access.redhat.com/errata/RHSA-2017:3471 https://access.redhat.com/errata/RHSA-2017:3472 https://access.redhat.com/errata/RH • CWE-248: Uncaught Exception •
