Local users could crash the D-Bus daemon by sending a specially crafted message (CVE-2010-4352). This update also properly fixes CVE-2008-3834 / CVE-2009-1189.

Updated dbus packages that fix a security issue are now available for Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

D-Bus is a system for sending messages between applications. It is used for the system-wide message bus service and as a per-user-login-session messaging facility.

It was discovered that the Red Hat Security Advisory RHSA-2009:0008 did not correctly fix the denial of service flaw in the system for sending messages between applications. A local user could use this flaw to send a message with a malformed signature to the bus, causing the bus (and, consequently, any process using libdbus to receive messages) to abort. (CVE-2009-1189)

Note: Users running any application providing services over the system message bus are advised to test this update carefully before deploying it in production environments.

All users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. For the update to take effect, all running instances of dbus-daemon and all running applications using the libdbus library must be restarted, or the system rebooted.

It was discovered that the dbus_signature_validate function in dbus, a simple interprocess messaging system, is prone to a denial of service attack. This issue was caused by an incorrect fix for DSA-1658-1.

The remote Oracle Linux 5 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2010-0018 advisory.

    [1.1.2-12.el5_4.1]
    - CVE-2009-1189 dbus: invalid fix for CVE-2008-3834

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote NewStart CGSL host, running version MAIN 6.02, has dbus packages installed that are affected by multiple vulnerabilities:

  - Unspecified vulnerability in the match_rule_equal function in bus/signals.c in D-Bus before 1.0.2 allows     local applications to remove match rules for other applications and cause a denial of service (lost     process messages). (CVE-2006-6107)

  - dbus-daemon in D-Bus before 1.0.3, and 1.1.x before 1.1.20, recognizes send_interface attributes in allow     directives in the security policy only for fully qualified method calls, which allows local users to     bypass intended access restrictions via a method call with a NULL interface. (CVE-2008-0595)

  - The _dbus_validate_signature_with_reason function (dbus-marshal-validate.c) in D-Bus (aka DBus) before     1.2.14 uses incorrect logic to validate a basic type, which allows remote attackers to spoof a signature     via a crafted key. NOTE: this is due to an incorrect fix for CVE-2008-3834. (CVE-2009-1189)

  - libdbus 1.5.x and earlier, when used in setuid or other privileged programs in X.org and possibly other     products, allows local users to gain privileges and execute arbitrary code via the DBUS_SYSTEM_BUS_ADDRESS     environment variable. NOTE: libdbus maintainers state that this is a vulnerability in the applications     that do not cleanse environment variables, not in libdbus itself: we do not support use of libdbus in     setuid binaries that do not sanitize their environment before their first call into libdbus.
    (CVE-2012-3524)

  - The _dbus_printf_string_upper_bound function in dbus/dbus-sysdeps-unix.c in D-Bus (aka DBus) 1.4.x before     1.4.26, 1.6.x before 1.6.12, and 1.7.x before 1.7.4 allows local users to cause a denial of service     (service crash) via a crafted message. (CVE-2013-2168)

  - The dbus-daemon in D-Bus 1.2.x through 1.4.x, 1.6.x before 1.6.20, and 1.8.x before 1.8.4, sends an     AccessDenied error to the service instead of a client when the client is prohibited from accessing the     service, which allows local users to cause a denial of service (initialization failure and exit) or     possibly conduct a side-channel attack via a D-Bus message to an inactive service. (CVE-2014-3477)

  - dbus 1.3.0 before 1.6.22 and 1.8.x before 1.8.6 allows local users to cause a denial of service     (disconnect) via a certain sequence of crafted messages that cause the dbus-daemon to forward a message     containing an invalid file descriptor. (CVE-2014-3533)

  - Off-by-one error in D-Bus 1.3.0 through 1.6.x before 1.6.24 and 1.8.x before 1.8.8, when running on a     64-bit system and the max_message_unix_fds limit is set to an odd number, allows local users to cause a     denial of service (dbus-daemon crash) or possibly execute arbitrary code by sending one more file     descriptor than the limit, which triggers a heap-based buffer overflow or an assertion failure.
    (CVE-2014-3635)

  - D-Bus 1.3.0 through 1.6.x before 1.6.24 and 1.8.x before 1.8.8 allows local users to (1) cause a denial of     service (prevention of new connections and connection drop) by queuing the maximum number of file     descriptors or (2) cause a denial of service (disconnect) via multiple messages that combine to have more     than the allowed number of file descriptors for a single sendmsg call. (CVE-2014-3636)

  - D-Bus 1.3.0 through 1.6.x before 1.6.24 and 1.8.x before 1.8.8 does not properly close connections for     processes that have terminated, which allows local users to cause a denial of service via a D-bus message     containing a D-Bus connection file descriptor. (CVE-2014-3637)

  - The bus_connections_check_reply function in config-parser.c in D-Bus before 1.6.24 and 1.8.x before 1.8.8     allows local users to cause a denial of service (CPU consumption) via a large number of method calls.
    (CVE-2014-3638)

  - The dbus-daemon in D-Bus before 1.6.24 and 1.8.x before 1.8.8 does not properly close old connections,     which allows local users to cause a denial of service (incomplete connection consumption and prevention of     new connections) via a large number of incomplete connections. (CVE-2014-3639)

  - D-Bus 1.3.0 through 1.6.x before 1.6.26, 1.8.x before 1.8.10, and 1.9.x before 1.9.2 allows local users to     cause a denial of service (prevention of new connections and connection drop) by queuing the maximum     number of file descriptors. NOTE: this vulnerability exists because of an incomplete fix for     CVE-2014-3636.1. (CVE-2014-7824)

  - D-Bus 1.4.x through 1.6.x before 1.6.30, 1.8.x before 1.8.16, and 1.9.x before 1.9.10 does not validate     the source of ActivationFailure signals, which allows local users to cause a denial of service (activation     failure error returned) by leveraging a race condition involving sending an ActivationFailure signal     before systemd responds. (CVE-2015-0245)

  - An issue was discovered in dbus >= 1.3.0 before 1.12.18. The DBusServer in libdbus, as used in dbus-     daemon, leaks file descriptors when a message exceeds the per-message file descriptor limit. A local     attacker with access to the D-Bus system bus or another system service's private AF_UNIX socket could use     this to make the system service reach its file descriptor limit, denying service to subsequent D-Bus     clients. (CVE-2020-12049)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

It was discovered that the last dbus security update did not correctly fix the denial of service flaw in the system for sending messages between applications. A local user could use this flaw to send a message with a malformed signature to the bus, causing the bus (and, consequently, any process using libdbus to receive messages) to abort.
(CVE-2009-1189)

Note: Users running any application providing services over the system message bus are advised to test this update carefully before deploying it in production environments.

For the update to take effect, all running instances of dbus-daemon and all running applications using the libdbus library must be restarted, or the system rebooted.

A vulnerability was discovered and corrected in dbus :

The _dbus_validate_signature_with_reason function (dbus-marshal-validate.c) in D-Bus (aka DBus) uses incorrect logic to validate a basic type, which allows remote attackers to spoof a signature via a crafted key. NOTE: this is due to an incorrect fix for CVE-2008-3834 (CVE-2009-1189).

This update provides a fix for this vulnerability.

Update :

Packages for 2008.0 are provided for Corporate Desktop 2008.0 customers

The remote VMware ESX host is missing a security-related patch. It is, therefore, affected by multiple vulnerabilities, including remote code execution vulnerabilities, in several third-party components and libraries :

  - bind
  - expat
  - glib2
  - Kernel
  - newt
  - nfs-utils
  - NTP
  - OpenSSH
  - OpenSSL

a. vMA and Service Console update for newt to 0.52.2-12.el5_4.1

   Newt is a programming library for color text mode, widget based    user interfaces. Newt can be used to add stacked windows, entry    widgets, checkboxes, radio buttons, labels, plain text fields,    scrollbars, etc., to text mode user interfaces.

   A heap-based buffer overflow flaw was found in the way newt    processes content that is to be displayed in a text dialog box.
   A local attacker could issue a specially crafted text dialog box    display request (direct or via a custom application), leading to a    denial of service (application crash) or, potentially, arbitrary    code execution with the privileges of the user running the    application using the newt library.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2009-2905 to this issue.

b. vMA and Service Console update for vMA package nfs-utils to    1.0.9-42.el5

   The nfs-utils package provides a daemon for the kernel NFS server    and related tools.

   It was discovered that nfs-utils did not use tcp_wrappers    correctly.  Certain hosts access rules defined in '/etc/hosts.allow'    and '/etc/hosts.deny' may not have been honored, possibly allowing    remote attackers to bypass intended access restrictions.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2008-4552 to this issue.

c. vMA and Service Console package glib2 updated to 2.12.3-4.el5_3.1

   GLib is the low-level core library that forms the basis for    projects such as GTK+ and GNOME. It provides data structure    handling for C, portability wrappers, and interfaces for such    runtime functionality as an event loop, threads, dynamic loading,    and an object system.

   Multiple integer overflows in glib/gbase64.c in GLib before 2.20    allow context-dependent attackers to execute arbitrary code via a    long string that is converted either from or to a base64    representation.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2008-4316 to this issue.

d. vMA and Service Console update for openssl to 0.9.8e-12.el5

   SSL is a toolkit implementing SSL v2/v3 and TLS protocols with full-    strength cryptography world-wide.

   Multiple denial of service flaws were discovered in OpenSSL's DTLS    implementation. A remote attacker could use these flaws to cause a    DTLS server to use excessive amounts of memory, or crash on an    invalid memory access or NULL pointer dereference.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the names CVE-2009-1377, CVE-2009-1378,    CVE-2009-1379, CVE-2009-1386, CVE-2009-1387 to these issues.

   An input validation flaw was found in the handling of the BMPString    and UniversalString ASN1 string types in OpenSSL's    ASN1_STRING_print_ex() function. An attacker could use this flaw to    create a specially crafted X.509 certificate that could cause    applications using the affected function to crash when printing    certificate contents.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2009-0590 to this issue.

e. vMA and Service Console package bind updated to 9.3.6-4.P1.el5_4.1

   It was discovered that BIND was incorrectly caching responses    without performing proper DNSSEC validation, when those responses    were received during the resolution of a recursive client query    that requested DNSSEC records but indicated that checking should be    disabled. A remote attacker could use this flaw to bypass the DNSSEC    validation check and perform a cache poisoning attack if the target    BIND server was receiving such client queries.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2009-4022 to this issue.

f. vMA and Service Console package expat updated to 1.95.8-8.3.el5_4.2.

   Two buffer over-read flaws were found in the way Expat handled    malformed UTF-8 sequences when processing XML files. A specially-    crafted XML file could cause applications using Expat to fail while    parsing the file.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the names CVE-2009-3560 and CVE-2009-3720 to these    issues.

g. vMA and Service Console package openssh update to 4.3p2-36.el5_4.2

   A Red Hat specific patch used in the openssh packages as shipped in    Red Hat Enterprise Linux 5.4 (RHSA-2009:1287) loosened certain    ownership requirements for directories used as arguments for the    ChrootDirectory configuration options. A malicious user that also    has or previously had non-chroot shell access to a system could    possibly use this flaw to escalate their privileges and run    commands as any system user.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2009-2904 to this issue.

h. vMA and Service Console package ntp updated to    ntp-4.2.2p1-9.el5_4.1.i386.rpm

   A flaw was discovered in the way ntpd handled certain malformed NTP    packets. ntpd logged information about all such packets and replied    with an NTP packet that was treated as malformed when received by    another ntpd. A remote attacker could use this flaw to create an NTP    packet reply loop between two ntpd servers through a malformed packet    with a spoofed source IP address and port, causing ntpd on those    servers to use excessive amounts of CPU time and fill disk space with    log messages.

   The Common Vulnerabilities and Exposures Project (cve.mitre.org)    has assigned the name CVE-2009-3563 to this issue.   

i. vMA update for package kernel to 2.6.18-164.9.1.el5

   Updated vMA package kernel addresses the security issues listed    below.

   The Common Vulnerabilities and Exposures project (cve.mitre.org)    has assigned the name CVE-2009-2849 to the security issue fixed in    kernel 2.6.18-128.2.1

   The Common Vulnerabilities and Exposures project (cve.mitre.org)    has assigned the names CVE-2009-2695, CVE-2009-2908, CVE-2009-3228,    CVE-2009-3286, CVE-2009-3547, CVE-2009-3613 to the security issues    fixed in kernel 2.6.18-128.6.1

   The Common Vulnerabilities and Exposures project (cve.mitre.org)    has assigned the names CVE-2009-3612, CVE-2009-3620, CVE-2009-3621,    CVE-2009-3726 to the security issues fixed in kernel    2.6.18-128.9.1

j. vMA 4.0 updates for the packages kpartx, libvolume-id,    device-mapper-multipath, fipscheck, dbus, dbus-libs, and ed

   kpartx updated to 0.4.7-23.el5_3.4, libvolume-id updated to    095-14.20.el5 device-mapper-multipath package updated to    0.4.7-23.el5_3.4, fipscheck updated to 1.0.3-1.el5, dbus    updated to 1.1.2-12.el5, dbus-libs updated to 1.1.2-12.el5,    and ed package updated to 0.2-39.el5_2.
