CVSS: 5.6EPSS: 0%CPEs: 665EXPL: 5CVE-2018-3639 – AMD / ARM / Intel - Speculative Execution Variant 4 Speculative Store Bypass
https://notcve.org/view.php?id=CVE-2018-3639
Systems with microprocessors utilizing speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis, aka Speculative Store Bypass (SSB), Variant 4. Los sistemas con microprocesadores que emplean la ejecución especulativa y que realizan la ejecución especulativa de lecturas de memoria antes de que se conozcan las direcciones de todas las anteriores escrituras de memoria podrían permitir la divulgación no autorizada de información a un atacante con acceso de usuario local mediante un análisis de canal lateral. Esto también se conoce como Speculative Store Bypass (SSB), Variant 4. An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of Load & Store instructions (a commonly used performance optimization). It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory read from address to which a recent memory write has occurred may see an older value and subsequently cause an update into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). • https://www.exploit-db.com/exploits/44695 https://github.com/mmxsrup/CVE-2018-3639 https://github.com/Shuiliusheng/CVE-2018-3639-specter-v4- https://github.com/malindarathnayake/Intel-CVE-2018-3639-Mitigation_RegistryUpdate http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00058.html http://lists.opensuse.org/opensuse-security-announce/2019-05/msg00059.html http://lists.opensuse.org/opensuse-security-announce/2020-09/msg00007.html http://support.lenovo.com/us/en/solutions/LEN-2213 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-203: Observable Discrepancy •

An integer overflow that could lead to an attacker-controlled heap out-of-bounds write in PDFium in Google Chrome prior to 66.0.3359.170 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted PDF file. Un desbordamiento de enteros que conduce a una escritura fuera de límites basada en memoria dinámica (heap) controlada por el atacante en PDFium en Google Chrome en versiones anteriores a la 66.0.3359.170 permitía que un atacante remoto ejecutase código arbitrario dentro de un sandbox mediante un archivo PDF manipulado. • http://www.securityfocus.com/bid/104143 https://access.redhat.com/errata/RHSA-2018:1446 https://chromereleases.googleblog.com/2018/05/stable-channel-update-for-desktop.html https://crbug.com/833721 https://security.gentoo.org/glsa/201805-06 https://www.debian.org/security/2018/dsa-4237 https://access.redhat.com/security/cve/CVE-2018-6120 https://bugzilla.redhat.com/show_bug.cgi?id=1577115 • CWE-190: Integer Overflow or Wraparound CWE-787: Out-of-bounds Write •

DHCP packages in Red Hat Enterprise Linux 6 and 7, Fedora 28, and earlier are vulnerable to a command injection flaw in the NetworkManager integration script included in the DHCP client. A malicious DHCP server, or an attacker on the local network able to spoof DHCP responses, could use this flaw to execute arbitrary commands with root privileges on systems using NetworkManager and configured to obtain network configuration using the DHCP protocol. Los paquetes DHCP en Red Hat Enterprise Linux 6 y 7, Fedora 28 y anteriores son vulnerables a un error de inyección de comandos en el script de integración NetworkManager incluido en el cliente DHCP.
