详细描述

dracut: dracut contains tools to create a bootable initramfs for 2.6 Linux kernels. Unlike existing implementations, dracut does hard-code as little as possible into the initramfs. dracut contains various modules which are driven by the event-based udev. Having root on MD, DM, LVM2, LUKS is supported as well as NFS, iSCSI, NBD, FCoE with the dracut-network package.

Security Fix(es):
dracut: An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of instructions (a commonly used performance optimization). There are three primary variants of the issue which differ in the way the speculative execution can be exploited. Variant CVE-2017-5715 triggers the speculative execution by utilizing branch target injection. It relies on the presence of a precisely-defined instruction sequence in the privileged code as well as the fact that memory accesses may cause allocation into the microprocessor's data cache even for speculatively executed instructions that never actually commit (retire). As a result, an unprivileged attacker could use this flaw to cross the syscall and guest/host boundaries and read privileged memory by conducting targeted cache side-channel attacks.(CVE-2017-5715)
dracut: bugfix
java-1.8.0-openjdk: ulnerability in the Java SE, Java SE Embedded, JRockit component of Oracle Java SE (subcomponent: JNDI). Supported versions that are affected are Java SE: 6u171, 7u161, 8u152 and 9.0.1; Java SE Embedded: 8u151; JRockit: R28.3.16. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Java SE, Java SE Embedded, JRockit. Successful attacks require human interaction from a person other than the attacker. 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: This vulnerability applies to client and server deployment of Java. This vulnerability can be exploited through sandboxed Java Web Start applications and sandboxed Java applets. It can also be exploited by supplying data to APIs in the specified Component without using sandboxed Java Web Start applications or sandboxed Java applets, such as through a web service. CVSS 3.0 Base Score 4.3 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L)(CVE-2018-2678)
java-1.8.0-openjdk: ulnerability in the Java SE, Java SE Embedded component of Oracle Java SE (subcomponent: AWT). Supported versions that are affected are Java SE: 6u171, 7u161, 8u152 and 9.0.1; Java SE Embedded: 8u151. Easily exploitable 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 ability to cause a partial denial of service (partial DOS) of Java SE, Java SE Embedded. Note: This vulnerability applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. This vulnerability does not apply to Java deployments, typically in servers, that load and run only trusted code (e.g., code installed by an administrator). CVSS 3.0 Base Score 4.3 (Availability impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L)(CVE-2018-2677)

java-1.8.0-openjdk: It was discovered that multiple encryption key classes in the Libraries component of OpenJDK did not properly synchronize access to their internal data. This could possibly cause a multi-threaded Java application to apply weak encryption to data because of the use of a key that was zeroed out(CVE-2018-2579)
java-1.8.0-openjdk: It was discovered that the LDAP component of OpenJDK failed to properly encode special characters in user names when adding them to an LDAP search query. A remote attacker could possibly use this flaw to manipulate LDAP queries performed by the LdapLoginModule class(CVE-2018-2588)
java-1.8.0-openjdk: It was discovered that the I18n component of OpenJDK could use an untrusted search path when loading resource bundle classes. A local attacker could possibly use this flaw to execute arbitrary code as another local user by making their Java application load an attacker controlled class fil(CVE-2018-2602)
java-1.8.0-openjdk: It was discovered that the DNS client implementation in the JNDI component of OpenJDK did not use random source ports when sending out DNS queries. This could make it easier for a remote attacker to spoof responses to those queries(CVE-2018-2599)
java-1.8.0-openjdk: It was discovered that the Libraries component of OpenJDK failed to sufficiently limit the amount of memory allocated when reading DER encoded input. A remote attacker could possibly use this flaw to make a Java application use an excessive amount of memory if it parsed attacker supplied DER encoded input(CVE-2018-2603)
java-1.8.0-openjdk: It was discovered that the JGSS component of OpenJDK failed to properly handle GSS context in the native GSS library wrapper in certain cases. A remote attacker could possibly make a Java application using JGSS to use a previously freed context(CVE-2018-2629)
java-1.8.0-openjdk: It was discovered that the key agreement implementations in the JCE component of OpenJDK did not guarantee sufficient strength of used keys to adequately protect generated shared secret. This could make it easier to break data encryption by attacking key agreement rather than the encryption using the negotiated secret(CVE-2018-2618)
java-1.8.0-openjdk: ulnerability in the Java SE, Java SE Embedded component of Oracle Java SE (subcomponent: AWT). Supported versions that are affected are Java SE: 6u171, 7u161, 8u152 and 9.0.1; Java SE Embedded: 8u151. 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 and while the vulnerability is in Java SE, Java SE Embedded, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Java SE, Java SE Embedded accessible data.
