CVSS: 7.4EPSS: 0%CPEs: 12EXPL: 0CVE-2017-12151 – samba: SMB2 connections don't keep encryption across DFS redirects
https://notcve.org/view.php?id=CVE-2017-12151
A flaw was found in the way samba client before samba 4.4.16, samba 4.5.14 and samba 4.6.8 used encryption with the max protocol set as SMB3. The connection could lose the requirement for signing and encrypting to any DFS redirects, allowing an attacker to read or alter the contents of the connection via a man-in-the-middle attack. Se ha encontrado un fallo en la forma en la que el cliente samba en versiones anteriores a samba 4.4.16, samba 4.5.14 y samba 4.6.8 utilizaba cifrado con el protocolo max establecido en SMB3. La conexión podía perder el requisito de firmar y cifrar con cualquier redirección DFS, lo que permitía a un atacante leer o alterar el contenido de la conexión mediante un ataque Man-in-the-Middle (MitM). A flaw was found in the way samba client used encryption with the max protocol set as SMB3. • http://www.securityfocus.com/bid/100917 http://www.securitytracker.com/id/1039401 https://access.redhat.com/errata/RHSA-2017:2790 https://access.redhat.com/errata/RHSA-2017:2858 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2017-12151 https://security.netapp.com/advisory/ntap-20170921-0001 https://support.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbux03817en_us https://www.debian.org/security/2017/dsa-3983 https://www.samba.org/samba/security/CVE-20 • CWE-300: Channel Accessible by Non-Endpoint CWE-310: Cryptographic Issues •
CVSS: 8.0EPSS: 0%CPEs: 43EXPL: 5CVE-2017-1000251 – Linux Kernel < 4.13.1 - BlueTooth Buffer Overflow (PoC)
https://notcve.org/view.php?id=CVE-2017-1000251
The native Bluetooth stack in the Linux Kernel (BlueZ), starting at the Linux kernel version 2.6.32 and up to and including 4.13.1, are vulnerable to a stack overflow vulnerability in the processing of L2CAP configuration responses resulting in Remote code execution in kernel space. La pila Bluetooth nativa en el Kernel Linux (BlueZ), comenzando por la versión 2.6.32 del kernel de Linux y hasta, e incluyendo, la versión 4.13.1, es vulnerable a un desbordamiento de pila durante el procesado de las respuestas de configuración L2CAP, lo que desemboca en la ejecución remota de código en el espacio del kernel. A stack buffer overflow flaw was found in the way the Bluetooth subsystem of the Linux kernel processed pending L2CAP configuration responses from a client. On systems with the stack protection feature enabled in the kernel (CONFIG_CC_STACKPROTECTOR=y, which is enabled on all architectures other than s390x and ppc64[le]), an unauthenticated attacker able to initiate a connection to a system via Bluetooth could use this flaw to crash the system. Due to the nature of the stack protection feature, code execution cannot be fully ruled out, although we believe it is unlikely. • https://www.exploit-db.com/exploits/42762 https://github.com/hayzamjs/Blueborne-CVE-2017-1000251 https://github.com/own2pwn/blueborne-CVE-2017-1000251-POC https://github.com/sgxgsx/blueborne-CVE-2017-1000251 https://github.com/tlatkdgus1/blueborne-CVE-2017-1000251 http://nvidia.custhelp.com/app/answers/detail/a_id/4561 http://www.debian.org/security/2017/dsa-3981 http://www.securityfocus.com/bid/100809 http://www.securitytracker.com/id/1039373 https://access.redhat.com/errata& • CWE-121: Stack-based Buffer Overflow CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2017-0902
RubyGems version 2.6.12 and earlier is vulnerable to a DNS hijacking vulnerability that allows a MITM attacker to force the RubyGems client to download and install gems from a server that the attacker controls. RubyGems 2.6.12 y anteriores es vulnerable a secuestro de DNS, lo que permite a un atacante Man-in-the-Middle (MitM) forzar el cliente RubyGems a que descargue e instale gemas desde un servidor que está bajo el control del atacante. A vulnerability was found where rubygems did not sanitize DNS responses when requesting the hostname of the rubygems server for a domain, via a _rubygems._tcp DNS SRV query. An attacker with the ability to manipulate DNS responses could direct the gem command towards a different domain. • http://blog.rubygems.org/2017/08/27/2.6.13-released.html http://www.securityfocus.com/bid/100586 http://www.securitytracker.com/id/1039249 https://access.redhat.com/errata/RHSA-2017:3485 https://access.redhat.com/errata/RHSA-2018:0378 https://access.redhat.com/errata/RHSA-2018:0583 https://access.redhat.com/errata/RHSA-2018:0585 https://github.com/rubygems/rubygems/commit/8d91516fb7037ecfb27622f605dc40245e0f8d32 https://hackerone.com/reports/218088 https://lists.debian.org/debian- • CWE-138: Improper Neutralization of Special Elements CWE-346: Origin Validation Error CWE-350: Reliance on Reverse DNS Resolution for a Security-Critical Action •
