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 •

Vulnerability in the Solaris component of Oracle Sun Systems Products Suite (subcomponent: LDAP Library). Supported versions that are affected are 10 and 11.3. Difficult to exploit vulnerability allows low privileged attacker with network access via LDAP to compromise Solaris. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Solaris accessible data as well as unauthorized read access to a subset of Solaris accessible data. CVSS 3.0 Base Score 4.2 (Confidentiality and Integrity impacts). • http://www.oracle.com/technetwork/security-advisory/cpuapr2018-3678067.html http://www.securityfocus.com/bid/103888 http://www.securitytracker.com/id/1040702 •

CVSS: 7.0EPSS: 0%CPEs: 3EXPL: 0CVE-2018-1171 – Joyent SmartOS DTrace DOF Out-Of-Bounds Write Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2018-1171
This vulnerability allows local attackers to escalate privileges on vulnerable installations of Joyent SmartOS release-20170803-20170803T064301Z. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the DTrace DOF files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated object. An attacker can leverage this vulnerability to execute code under the context of the host OS. • http://www.oracle.com/technetwork/security-advisory/cpujul2018-4258247.html http://www.securityfocus.com/bid/104799 http://www.securitytracker.com/id/1041303 https://help.joyent.com/hc/en-us/articles/360000608188 https://zerodayinitiative.com/advisories/ZDI-18-236 • CWE-787: Out-of-bounds Write •
