Red Hat Security Advisory 2012-0874-04 - MySQL is a multi-user, multi-threaded SQL database server. It consists of the MySQL server daemon and many client programs and libraries. A flaw was found in the way MySQL processed HANDLER READ NEXT statements after deleting a record. A remote, authenticated attacker could use this flaw to provide such requests, causing mysqld to crash. This issue only caused a temporary denial of service, as mysqld was automatically restarted after the crash.

Red Hat Security Advisory 2012-0810-04 - BusyBox provides a single binary that includes versions of a large number of system commands, including a shell. This can be very useful for recovering from certain types of system failures, particularly those involving broken shared libraries. A buffer underflow flaw was found in the way the uncompress utility of BusyBox expanded certain archive files compressed using Lempel-Ziv compression. If a user were tricked into expanding a specially-crafted archive file with uncompress, it could cause BusyBox to crash or, potentially, execute arbitrary code with the privileges of the user running BusyBox.

Red Hat Security Advisory 2012-0813-04 - The 389 Directory Server is an LDAPv3 compliant server. The base packages include the Lightweight Directory Access Protocol server and command-line utilities for server administration. A flaw was found in the way the 389 Directory Server daemon handled access control instructions using certificate groups. If an LDAP user that had a certificate group defined attempted to bind to the directory server, it would cause ns-slapd to enter an infinite loop and consume an excessive amount of CPU time.

Red Hat Security Advisory 2012-0899-04 - OpenLDAP is an open source suite of LDAP applications and development tools. A denial of service flaw was found in the way the OpenLDAP server daemon processed certain search queries requesting only attributes and no values. In certain configurations, a remote attacker could issue a specially-crafted LDAP search query that, when processed by slapd, would cause slapd to crash due to an assertion failure. These updated openldap packages include numerous bug fixes. Space precludes documenting all of these changes in this advisory. Users are directed to the Red Hat Enterprise Linux 6.3 Technical Notes for information on the most significant of these changes.

Red Hat Security Advisory 2012-0796-04 - The rsyslog packages provide an enhanced, multi-threaded syslog daemon. A numeric truncation error, leading to a heap-based buffer overflow, was found in the way the rsyslog imfile module processed text files containing long lines. An attacker could use this flaw to crash the rsyslogd daemon or, possibly, execute arbitrary code with the privileges of rsyslogd, if they are able to cause a long line to be written to a log file that rsyslogd monitors with imfile. The imfile module is not enabled by default.

Red Hat Security Advisory 2012-0880-04 - Qt is a software toolkit that simplifies the task of writing and maintaining GUI applications for the X Window System. HarfBuzz is an OpenType text shaping engine. A buffer overflow flaw was found in the harfbuzz module in Qt. If a user loaded a specially-crafted font file with an application linked against Qt, it could cause the application to crash or, possibly, execute arbitrary code with the privileges of the user running the application. A flaw was found in the way Qt handled X.509 certificates with IP address wildcards. An attacker able to obtain a certificate with a Common Name containing an IP wildcard could possibly use this flaw to impersonate an SSL server to client applications that are using Qt. This update also introduces more strict handling for hostname wildcard certificates by disallowing the wildcard character to match more than one hostname component.

Red Hat Security Advisory 2012-0774-04 - libguestfs is a library for accessing and modifying guest disk images. It was found that editing files with virt-edit left said files in a world-readable state. If an administrator on the host used virt-edit to edit a file inside a guest, the file would be left with world-readable permissions. This could lead to unprivileged guest users accessing files they would otherwise be unable to. These updated libguestfs packages include numerous bug fixes and enhancements. Space precludes documenting all of these changes in this advisory. Users are directed to the Red Hat Enterprise Linux 6.3 Technical Notes for information on the most significant of these changes.

Red Hat Security Advisory 2012-0748-05 - The libvirt library is a C API for managing and interacting with the virtualization capabilities of Linux and other operating systems. In addition, libvirt provides tools for remote management of virtualized systems. Bus and device IDs were ignored when attempting to attach multiple USB devices with identical vendor or product IDs to a guest. This could result in the wrong device being attached to a guest, giving that guest root access to the device. These updated libvirt packages include numerous bug fixes and enhancements. Space precludes documenting all of these changes in this advisory. Users are directed to the Red Hat Enterprise Linux 6.3 Technical Notes for information on the most significant of these changes.

Red Hat Security Advisory 2012-1013-01 - The Java Authorization Contract for Containers specification defines Permission classes and the binding of container access decisions to operations on instances of these permission classes. JaccAuthorizationRealm performs authorization based on Java ACC permissions and a Policy implementation. When a JBoss server is configured to use JaccAuthorizationRealm, the WebPermissionMapping class creates permissions that are not checked and can permit access to users without checking their roles. If the ignoreBaseDecision property is set to true on JBossWebRealm, the web authorization process is handled exclusively by JBossAuthorizationEngine, without any input from JBoss Web. This allows any valid user to access an application, without needing to be assigned the role specified in the application's web.xml "security-constraint" tag.

Red Hat Security Advisory 2012-1012-01 - mod_cluster is an Apache HTTP Server based load balancer that forwards requests from httpd to application server nodes. It can use the AJP, HTTP, or HTTPS protocols for communication with application server nodes. The RHSA-2012:0036 update for JBoss Enterprise Web Server 1.0.2 introduced a regression, causing mod_cluster to register and expose the root context of a server by default, even when "ROOT" was in the "excludedContexts" list in the mod_cluster configuration. If an application was deployed on the root context, a remote attacker could use this flaw to bypass intended access restrictions and gain access to that application.

Red Hat Security Advisory 2012-0745-01 - Python is an interpreted, interactive, object-oriented programming language. A denial of service flaw was found in the implementation of associative arrays in Python. An attacker able to supply a large number of inputs to a Python application that are used as keys when inserting data into an array could trigger multiple hash function collisions, making array operations take an excessive amount of CPU time. To mitigate this issue, randomization has been added to the hash function to reduce the chance of an attacker successfully causing intentional collisions.

Red Hat Security Advisory 2012-0743-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. A local, unprivileged user could use an integer overflow flaw in drm_mode_dirtyfb_ioctl() to cause a denial of service or escalate their privileges. A buffer overflow flaw was found in the macvtap device driver, used for creating a bridged network between the guest and the host in KVM environments. A privileged guest user in a KVM guest could use this flaw to crash the host. Note: This issue only affected hosts that have the vhost_net module loaded with the experimental_zcopytx module option enabled, and that also have macvtap configured for at least one guest.

Red Hat Security Advisory 2012-0731-01 - Expat is a C library written by James Clark for parsing XML documents. A denial of service flaw was found in the implementation of hash arrays in Expat. An attacker could use this flaw to make an application using Expat consume an excessive amount of CPU time by providing a specially-crafted XML file that triggers multiple hash function collisions. To mitigate this issue, randomization has been added to the hash function to reduce the chance of an attacker successfully causing intentional collisions. A memory leak flaw was found in Expat. If an XML file processed by an application linked against Expat triggered a memory re-allocation failure, Expat failed to free the previously allocated memory. This could cause the application to exit unexpectedly or crash when all available memory is exhausted.
