CVSS: 7.5EPSS: 0%CPEs: 13EXPL: 0CVE-2018-1128 – ceph: cephx protocol is vulnerable to replay attack
https://notcve.org/view.php?id=CVE-2018-1128
It was found that cephx authentication protocol did not verify ceph clients correctly and was vulnerable to replay attack. Any attacker having access to ceph cluster network who is able to sniff packets on network can use this vulnerability to authenticate with ceph service and perform actions allowed by ceph service. Ceph branches master, mimic, luminous and jewel are believed to be vulnerable. Se ha descubierto que el protocolo de autenticación cephx no verificaba correctamente los clientes ceph y era vulnerable a ataques de reproducción. Cualquier atacante que tenga acceso a la red de clústers de ceph y que pueda rastrear paquetes en la red puede emplear esta vulnerabilidad para autenticarse con el servicio ceph y realizar acciones permitidas por el servicio ceph. • http://lists.opensuse.org/opensuse-security-announce/2019-04/msg00100.html http://tracker.ceph.com/issues/24836 http://www.openwall.com/lists/oss-security/2020/11/17/3 http://www.openwall.com/lists/oss-security/2020/11/17/4 https://access.redhat.com/errata/RHSA-2018:2177 https://access.redhat.com/errata/RHSA-2018:2179 https://access.redhat.com/errata/RHSA-2018:2261 https://access.redhat.com/errata/RHSA-2018:2274 https://bugzilla.redhat.com/show_bug.cgi?id=1575866& • CWE-287: Improper Authentication CWE-294: Authentication Bypass by Capture-replay •

A flaw was found in the way signature calculation was handled by cephx authentication protocol. An attacker having access to ceph cluster network who is able to alter the message payload was able to bypass signature checks done by cephx protocol. Ceph branches master, mimic, luminous and jewel are believed to be vulnerable. Se ha encontrado un error en la forma en la que el cálculo de firmas es gestionado por el protocolo de autenticación cephx.

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 •

The xmlreader in libxml allows remote attackers to cause a denial of service (memory consumption) via crafted XML data, related to an XML Entity Expansion (XEE) attack. Vulnerabilidad en el xmlreader en libxml, permite a atacantes remotos causar una denegación de servicio (consumo de memoria) a través de datos XML manipulados, relacionada con un ataque XML Entity Expansión (XEE). A denial of service flaw was found in the way the libxml2 library parsed certain XML files. An attacker could provide a specially crafted XML file that, when parsed by an application using libxml2, could cause that application to use an excessive amount of memory. • http://lists.apple.com/archives/security-announce/2016/Mar/msg00000.html http://lists.apple.com/archives/security-announce/2016/Mar/msg00001.html http://lists.apple.com/archives/security-announce/2016/Mar/msg00002.html http://lists.apple.com/archives/security-announce/2016/Mar/msg00004.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/172710.html http://lists.fedoraproject.org/pipermail/package-announce/2015-November/172943.html http://lists.opensuse.org/opensuse-updates/2015- • CWE-399: Resource Management Errors •
