CVE-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 •
CVE-2018-2796 – OpenJDK: unbounded memory allocation during deserialization in PriorityBlockingQueue (Concurrency, 8189981)
https://notcve.org/view.php?id=CVE-2018-2796
Vulnerability in the Java SE, Java SE Embedded, JRockit component of Oracle Java SE (subcomponent: Concurrency). Supported versions that are affected are Java SE: 7u171, 8u162 and 10; Java SE Embedded: 8u161; JRockit: R28.3.17. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded, JRockit. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Java SE, Java SE Embedded, JRockit. Note: Applies to client and server deployment of Java. • http://www.oracle.com/technetwork/security-advisory/cpuapr2018-3678067.html http://www.securityfocus.com/bid/103868 http://www.securitytracker.com/id/1040697 https://access.redhat.com/errata/RHSA-2018:1188 https://access.redhat.com/errata/RHSA-2018:1191 https://access.redhat.com/errata/RHSA-2018:1201 https://access.redhat.com/errata/RHSA-2018:1202 https://access.redhat.com/errata/RHSA-2018:1204 https://access.redhat.com/errata/RHSA-2018:1206 https://access.redhat.com/errata/ • CWE-770: Allocation of Resources Without Limits or Throttling •

Vulnerability in the Java SE, Java SE Embedded component of Oracle Java SE (subcomponent: Security). Supported versions that are affected are Java SE: 6u181, 7u171, 8u162 and 10; Java SE Embedded: 8u161. Difficult to exploit vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Java SE, Java SE Embedded accessible data. • http://www.oracle.com/technetwork/security-advisory/cpuapr2018-3678067.html http://www.securityfocus.com/bid/103877 http://www.securitytracker.com/id/1040697 https://access.redhat.com/errata/RHSA-2018:1188 https://access.redhat.com/errata/RHSA-2018:1191 https://access.redhat.com/errata/RHSA-2018:1201 https://access.redhat.com/errata/RHSA-2018:1202 https://access.redhat.com/errata/RHSA-2018:1203 https://access.redhat.com/errata/RHSA-2018:1204 https://access.redhat.com/errata/ • CWE-347: Improper Verification of Cryptographic Signature •
