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 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). As a result, an unprivileged attacker could use this flaw to read privileged memory by conducting targeted cache side-channel attacks. (CVE-2018-3639, x86 AMD)

* kernel: Use-after-free vulnerability in mm/mempolicy.c:do_get_mempolicy function allows local denial of service or other unspecified impact (CVE-2018-10675)

* Kernel: FPU state information leakage via lazy FPU restore (CVE-2018-3665)

Security Fix(es) :

* A flaw was found in the way the DES/3DES cipher was used as part of the TLS /SSL protocol. A man-in-the-middle attacker could use this flaw to recover some plaintext data by capturing large amounts of encrypted traffic between TLS/SSL server and client if the communication used a DES/3DES based ciphersuite. (CVE-2016-2183)

Red Hat would like to thank Ken Johnson (Microsoft Security Response Center) and Jann Horn (Google Project Zero) for reporting this issue.

Bug Fix(es) :

* Previously, the virtlogd service logged redundant AVC denial errors when a guest virtual machine was started. With this update, the virtlogd service no longer attempts to send shutdown inhibition calls to systemd, which prevents the described errors from occurring.
(BZ#1573268)

* Prior to this update, guest virtual machine actions that use a python library in some cases failed and 'Hash operation not allowed during iteration' error messages were logged. Several redundant thread access checks have been removed, and the problem no longer occurs.
(BZ#1581364)

* The 'virsh capabilities' command previously displayed an inaccurate number of 4 KiB memory pages on systems with very large amounts of memory. This update optimizes the memory diagnostic mechanism to ensure memory page numbers are displayed correctly on such systems.
(BZ#1582418)

* pki-core: Mishandled ACL configuration in AAclAuthz.java reverses rules that allow and deny access (CVE-2018-1080)

For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.

This issue was discovered by Fraser Tweedale (Red Hat).

Bug Fix(es) :

* Previously, when ECC keys were enrolled, Certificate Management over CMS (CMC) authentication failed with a 'TokenException: Unable to insert certificate into temporary database' error. As a consequence, the enrollment failed. This update fixes the problem. As a result, the mentioned bug no longer occurs. (BZ#1550581)

* Previously, Certificate System used the same enrollment profiles for issuing RSA and ECC certificates. As a consequence, the key usage extension in issued certificates did not meet the Common Criteria standard. This update adds ECC-specific enrollment profiles where the key usage extension for TLS server and client certificates are different as described in RFC 6960. Additionally, the update changes existing profiles to issue only RSA certificates. As a result, the key usage extension in ECC certificates now meets the Common Criteria standard. (BZ#1554726)

* The Certificate System server rejects saving invalid access control lists (ACL). As a consequence, when saving an ACL with an empty expression, the server rejected the update and the pkiconsole utility displayed an StringIndexOutOfBoundsException error. With this update, the utility rejects empty ACL expressions. As a result, invalid ACLs cannot be saved and the error is no longer displayed. (BZ#1557883)

* Previously, due to a bug in the Certificate System installation procedure, installing a Key Recovery Authority (KRA) with ECC keys failed. To fix the problem, the installation process has been updated to handle both RSA and ECC subsystems automatically. As a result, installing subsystems with ECC keys no longer fail. (BZ#1581134)

* Previously, during verification, Certificate System encoded the ECC public key incorrectly in CMC Certificate Request Message Format (CRMF) requests. As a consequence, requesting an ECC certificate with Certificate Management over CMS (CMC) in CRMF failed. The problem has been fixed, and as a result, CMC CRMF requests using ECC keys work as expected. (BZ#1585945)

Enhancement(s) :

* The pkispawn man page has been updated and now describes the
--skip-configuration and --skip-installation parameters. (BZ#1551067)

* With this update, Certificate System adds the Subject Alternative Name (SAN) extension by default to server certificates and sets it to the Common Name (CN) of the certificate. (BZ#1581135)

* With this enhancement, users can create Certificate Request Message Format (CRMF) requests without the key archival option when using the CRMFPopClient utility. This feature increases flexibility because a Key Recovery Authority (KRA) certificate is no longer required.
Previously, if the user did not pass the '-b transport_certificate_file' option to CRMFPopClient, the utility automatically used the KRA transport certificate stored in the transport.txt file. With this update, if '-b transport_certificate_file' is not specified, Certificate System creates a request without using key archival. (BZ#1588945)

Git is a distributed revision control system with a decentralized architecture. As opposed to centralized version control systems with a client-server model, Git ensures that each working copy of a Git repository is an exact copy with complete revision history. This not only allows the user to work on and contribute to projects without the need to have permission to push the changes to their official repositories, but also makes it possible for the user to work with no network connection.

* git: arbitrary code execution when recursively cloning a malicious repository (CVE-2018-11235)

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 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). As a result, an unprivileged attacker could use this flaw to read privileged memory by conducting targeted cache side-channel attacks. (CVE-2018-3639, PowerPC)

* kernel: net/packet: overflow in check for priv area size (CVE-2017-7308)

* kernel: AIO interface didn't use rw_verify_area() for checking mandatory locking on files and size of access (CVE-2012-6701)

The CVE-2018-1064 issue was discovered by Daniel P. Berrange (Red Hat) and the CVE-2018-5748 issue was discovered by Daniel P. Berrange (Red Hat) and Peter Krempa (Red Hat).

Bug Fix(es) :

* Previously, the check for a non-unique device boot order did not properly handle updates of existing devices when a new device was attached to a guest. Consequently, updating any device with a specified boot order failed. With this update, the duplicity check detects correctly handles updates and ignores the original device, which avoids reporting false conflicts. As a result, updating a device with a boot order succeeds. (BZ# 1557922)

* In Red Hat Enterprise Linux 7.5, guests with SCSI passthrough enabled failed to boot because of changes in kernel CGroup detection.
With this update, libvirt fetches dependencies and adds them to the device CGroup. As a result, and the affected guests now start as expected. (BZ#1564996)

* The VMX parser in libvirt did not parse more than four network interfaces. As a consequence, the esx driver did not expose more than four network interface cards (NICs) for guests running ESXi. With this update, the VMX parser parses all the available NICs in .vmx files. As a result, libvirt reports all the NICs of guests running ESXi.
(BZ#1566524)

* Previously, user aliases for PTY devices that were longer than 32 characters were not supported. Consequently, if a domain included a PTY device with a user alias longer than 32 characters, the domain would not start. With this update, a static buffer was replaced with a dynamic buffer. As a result, the domain starts even if the length of the user alias for a PTY device is longer than 32 characters.
(BZ#1566525)

For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.

Red Hat would like to thank Greg Kubok for reporting this issue.

Bug Fix(es) :

* Indexing tasks in Directory Server contain the nsTaskStatus attribute to monitor whether the task is completed and the database is ready to receive updates. Before this update, the server set the value that indexing had completed before the database was ready to receive updates. Applications which monitor nsTaskStatus could start sending updates as soon as indexing completed, but before the database was ready. As a consequence, the server rejected updates with an UNWILLING_TO_PERFORM error. The problem has been fixed. As a result, the nsTaskStatus attribute now shows that indexing is completed after the database is ready to receive updates. (BZ#1553605)

* Previously, Directory Server did not remember when the first operation, bind, or a connection was started. As a consequence, the server applied in certain situations anonymous resource limits to an authenticated client. With this update, Directory Server properly marks authenticated client connections. As a result, it applies the correct resource limits, and authenticated clients no longer get randomly restricted by anonymous resource limits. (BZ#1554720)

* When debug replication logging is enabled, Directory Server incorrectly logged an error that updating the replica update vector (RUV) failed when in fact the update succeeded. The problem has been fixed, and the server no longer logs an error if updating the RUV succeeds. (BZ#1559464)

* This update adds the -W option to the ds-replcheck utility. With this option, ds-replcheck asks for the password, similar to OpenLDAP utilities. As a result, the password is not stored in the shell's history file when the -W option is used. (BZ#1559760)

* If an administrator moves a group in Directory Server from one subtree to another, the memberOf plug-in deletes the memberOf attribute with the old value and adds a new memberOf attribute with the new group's distinguished name (DN) in affected user entries.
Previously, if the old subtree was not within the scope of the memberOf plug-in, deleting the old memberOf attribute failed because the values did not exist. As a consequence, the plug-in did not add the new memberOf value, and the user entry contained an incorrect memberOf value. With this update, the plug-in now checks the return code when deleting the old value. If the return code is 'no such value', the plug-in only adds the new memberOf value. As a result, the memberOf attribute information is correct. (BZ#1559764)

* In a Directory Server replication topology, updates are managed by using Change Sequence Numbers (CSN) based on time stamps. New CSNs must be higher than the highest CSN present in the relative update vector (RUV). In case the server generates a new CSN in the same second as the most recent CSN, the sequence number is increased to ensure that it is higher. However, if the most recent CSN and the new CSN were identical, the sequence number was not increased. In this situation, the new CSN was, except the replica ID, identical to the most recent one. As a consequence, a new update in the directory appeared in certain situations older than the most recent update. With this update, Directory Server increases the CSN if the sequence number is lower or equal to the most recent one. As a result, new updates are no longer considered older than the most recent data. (BZ#1563079)
