Bug Fixes :

* If a fibre channel (FC) switch was powered down and then powered on again, the SCSI device driver stopped permanently the SCSI device's request queue. Consequently, the FC port login failed, leaving the port state as 'Bypassed' instead of 'Online', and users had to reboot the operating system. This update fixes the driver to avoid the permanent stop of the request queue. As a result, SCSI device now continues working as expected after power cycling the FC switch.
(BZ#1519857)

* Previously, on final close or unlink of a file, the find_get_pages() function in the memory management sometimes found no pages even if there were some pages left to save. Consequently, a kernel crash occurred when attempting to enter the unlink() function. This update fixes the find_get_pages() function in the memory management code to not return 0 too early. As a result, the kernel no longer crashes due to this behavior.(BZ# 1527811)

* Using IPsec connections under a heavy load could previously lead to a network performance degradation, especially when using the aesni-intel module. This update fixes the issue by making the cryptd queue length configurable so that it can be increased to prevent an overflow and packet drop. As a result, using IPsec under a heavy load no longer reduces network performance. (BZ#1527802)

* Previously, a deadlock in the bnx2fc driver caused all adapters to block and the SCSI error handler to become unresponsive. As a result, data transferring through the adapter was sometimes blocked. This update fixes bnx2fc, and data transferring through the adapter is no longer blocked due to this behavior. (BZ#1523783)

* If an NFSv3 client mounted a subdirectory of an exported file system, a directory entry to the mount hosting the export was incorrectly held even after clearing the cache. Consequently, attempts to unmount the subdirectory with the umount command failed with the EBUSY error. With this update, the underlying source code has been fixed, and the unmount operation now succeeds as expected in the described situation. (BZ#1535938)

Users of kernel are advised to upgrade to these updated packages, which fix these bugs. The system must be rebooted for this update to take effect.

Ruby is an extensible, interpreted, object-oriented, scripting language. It has features to process text files and to perform system management tasks.

Security Fix(es) :

* It was discovered that the Net::FTP module did not properly process filenames in combination with certain operations. A remote attacker could exploit this flaw to execute arbitrary commands by setting up a malicious FTP server and tricking a user or Ruby application into downloading files with specially crafted names using the Net::FTP module. (CVE-2017-17405)

* A buffer underflow was found in ruby's sprintf function. An attacker, with ability to control its format string parameter, could send a specially crafted string that would disclose heap memory or crash the interpreter. (CVE-2017-0898)

* It was found that rubygems did not sanitize gem names during installation of a given gem. A specially crafted gem could use this flaw to install files outside of the regular directory.
(CVE-2017-0901)

* A vulnerability was found where rubygems did not sanitize DNS responses when requesting the hostname of the rubygems server for a domain, via a _rubygems._tcp DNS SRV query. An attacker with the ability to manipulate DNS responses could direct the gem command towards a different domain. (CVE-2017-0902)

* A vulnerability was found where the rubygems module was vulnerable to an unsafe YAML deserialization when inspecting a gem. Applications inspecting gem files without installing them can be tricked to execute arbitrary code in the context of the ruby interpreter. (CVE-2017-0903)

* It was found that WEBrick did not sanitize all its log messages. If logs were printed in a terminal, an attacker could interact with the terminal via the use of escape sequences. (CVE-2017-10784)

* It was found that the decode method of the OpenSSL::ASN1 module was vulnerable to buffer underrun. An attacker could pass a specially crafted string to the application in order to crash the ruby interpreter, causing a denial of service. (CVE-2017-14033)

The java-1.7.0-openjdk packages provide the OpenJDK 7 Java Runtime Environment and the OpenJDK 7 Java Software Development Kit.

Security Fix(es) :

* A flaw was found in the AWT component of OpenJDK. An untrusted Java application or applet could use this flaw to bypass certain Java sandbox restrictions. (CVE-2018-2641)

* It was discovered that the LDAPCertStore class in the JNDI component of OpenJDK failed to securely handle LDAP referrals. An attacker could possibly use this flaw to make it fetch attacker controlled certificate data. (CVE-2018-2633)

* The JGSS component of OpenJDK ignores the value of the javax.security.auth.useSubjectCredsOnly property when using HTTP/SPNEGO authentication and always uses global credentials. It was discovered that this could cause global credentials to be unexpectedly used by an untrusted Java application. (CVE-2018-2634)

* It was discovered that the JMX component of OpenJDK failed to properly set the deserialization filter for the SingleEntryRegistry in certain cases. A remote attacker could possibly use this flaw to bypass intended deserialization restrictions. (CVE-2018-2637)

* 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)

* 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)

* 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 file. (CVE-2018-2602)

* 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)

* 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)

* 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)

* It was discovered that multiple classes in the Libraries, AWT, and JNDI components of OpenJDK did not sufficiently validate input when creating object instances from the serialized form. A specially crafted input could cause a Java application to create objects with an inconsistent state or use an excessive amount of memory when deserialized. (CVE-2018-2663, CVE-2018-2677, CVE-2018-2678)

* 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)

389 Directory Server is an LDAP version 3 (LDAPv3) compliant server.
The base packages include the Lightweight Directory Access Protocol (LDAP) server and command-line utilities for server administration.

Security Fix(es) :

* A stack-based buffer overflow flaw was found in the way 389-ds-base handled certain LDAP search filters. A remote, unauthenticated attacker could potentially use this flaw to make ns-slapd crash via a specially crafted LDAP request, thus resulting in denial of service.
(CVE-2017-15134)

Bug Fix(es) :

* Previously, when a connection received a high operation rate, Directory Server stopped to poll the connection in certain situations.
As a consequence, new requests on the connection were not detected and processed. With this update, Directory Server correctly decides whether a connection has to be polled. As a result, connections with a high request rate no longer remain unprocessed. (BZ#1523505)

* Previously, if Directory Server was stopped during an operation which created additional changes in the memory changelog, the Replication Update Vector (RUV) in the changelog was higher than the RUV in the database. As a consequence, Directory Server recreated the changelog when the server started. With this update, the server now writes the highest RUV to the changelog only if there is the highest Change Sequence Number (CSN) present in it. As a result, the database and the changelog RUV are consistent and the server does not need recreating the changelog at start up. (BZ#1523507)

* Due to a bug, using a large number of Class of Service (CoS) templates in Directory Server increased the virtual attribute processing time. This update improves the structure of the CoS storage. As a result, using a large number of CoS templates no longer increases the virtual attribute processing time. (BZ#1526928)

An update for dhcp is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Security Fix(es) :

* It was found that the DHCP daemon did not properly clean up closed OMAPI connections in certain cases. A remote attacker able to connect to the OMAPI port could use this flaw to exhaust file descriptors in the DHCP daemon, leading to a denial of service in the OMAPI functionality. (CVE-2017-3144)

An update for kernel is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security Fix(es) :

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.

Note: This issue is present in hardware and cannot be fully fixed via software update. The updated kernel packages provide software mitigation for this hardware issue at a cost of potential performance penalty. Please refer to References section for further information about this issue and the performance impact.

In this update initial mitigations for IBM Power (PowerPC) and IBM zSeries (S390) architectures are provided.

* 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. This fix specifically addresses S390 processors. (CVE-2017-5715, Important)

* Variant CVE-2017-5753 triggers the speculative execution by performing a bounds-check bypass. 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 boundary and read privileged memory by conducting targeted cache side-channel attacks. This fix specifically addresses S390 and PowerPC processors. (CVE-2017-5753, Important)

* Variant CVE-2017-5754 relies on the fact that, on impacted microprocessors, during speculative execution of instruction permission faults, exception generation triggered by a faulting access is suppressed until the retirement of the whole instruction block. In a combination with the fact that memory accesses may populate the cache even when the block is being dropped and never committed (executed), an unprivileged local attacker could use this flaw to read privileged (kernel space) memory by conducting targeted cache side-channel attacks. Note: CVE-2017-5754 affects Intel x86-64 microprocessors. AMD x86-64 microprocessors are not affected by this issue. This fix specifically addresses PowerPC processors.

Mozilla Firefox is an open source web browser.

This update upgrades Firefox to version 52.6.0 ESR.

Security Fix(es) :

* Multiple flaws were found in the processing of malformed web content. A web page containing malicious content could cause Firefox to crash or, potentially, execute arbitrary code with the privileges of the user running Firefox. (CVE-2018-5089, CVE-2018-5091, CVE-2018-5095, CVE-2018-5096, CVE-2018-5097, CVE-2018-5098, CVE-2018-5099, CVE-2018-5102, CVE-2018-5103, CVE-2018-5104, CVE-2018-5117)

* To mitigate timing-based side-channel attacks similar to 'Spectre' and 'Meltdown', the resolution of performance.now() has been reduced from 5ms to 20ms.

Red Hat would like to thank the Mozilla project for reporting these issues.

An update for bind is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

The Berkeley Internet Name Domain (BIND) is an implementation of the Domain Name System (DNS) protocols. BIND includes a DNS server (named); a resolver library (routines for applications to use when interfacing with DNS); and tools for verifying that the DNS server is operating correctly.

Security Fix(es) :

* A use-after-free flaw leading to denial of service was found in the way BIND internally handled cleanup operations on upstream recursion fetch contexts. A remote attacker could potentially use this flaw to make named, acting as a DNSSEC validating resolver, exit unexpectedly with an assertion failure via a specially crafted DNS request.
(CVE-2017-3145)

Red Hat would like to thank ISC for reporting this issue. Upstream acknowledges Jayachandran Palanisamy (Cygate AB) as the original reporter.

An update for java-1.8.0-openjdk is now available for Red Hat Enterprise Linux 6 and Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

The java-1.8.0-openjdk packages provide the OpenJDK 8 Java Runtime Environment and the OpenJDK 8 Java Software Development Kit.

Security Fix(es) :

* Multiple flaws were found in the Hotspot and AWT components of OpenJDK. An untrusted Java application or applet could use these flaws to bypass certain Java sandbox restrictions. (CVE-2018-2582, CVE-2018-2641)

* It was discovered that the LDAPCertStore class in the JNDI component of OpenJDK failed to securely handle LDAP referrals. An attacker could possibly use this flaw to make it fetch attacker controlled certificate data. (CVE-2018-2633)

* The JGSS component of OpenJDK ignores the value of the javax.security.auth.useSubjectCredsOnly property when using HTTP/SPNEGO authentication and always uses global credentials. It was discovered that this could cause global credentials to be unexpectedly used by an untrusted Java application. (CVE-2018-2634)

* It was discovered that the JMX component of OpenJDK failed to properly set the deserialization filter for the SingleEntryRegistry in certain cases. A remote attacker could possibly use this flaw to bypass intended deserialization restrictions. (CVE-2018-2637)

* 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)

* 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)

* 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 file. (CVE-2018-2602)

* 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)

* 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)

* 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)

* It was discovered that multiple classes in the Libraries, AWT, and JNDI components of OpenJDK did not sufficiently validate input when creating object instances from the serialized form. A specially crafted input could cause a Java application to create objects with an inconsistent state or use an excessive amount of memory when deserialized. (CVE-2018-2663, CVE-2018-2677, CVE-2018-2678)

* 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)

Note: If the web browser plug-in provided by the icedtea-web package was installed, the issues exposed via Java applets could have been exploited without user interaction if a user visited a malicious website.
