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.

The remote NewStart CGSL host, running version MAIN 6.06 (SP), has dbus packages installed that are affected by multiple vulnerabilities:

  - dbus before 1.10.28, 1.12.x before 1.12.16, and 1.13.x before 1.13.12, as used in DBusServer in Canonical     Upstart in Ubuntu 14.04 (and in some, less common, uses of dbus-daemon), allows cookie spoofing because of     symlink mishandling in the reference implementation of DBUS_COOKIE_SHA1 in the libdbus library. (This only     affects the DBUS_COOKIE_SHA1 authentication mechanism.) A malicious client with write access to its own     home directory could manipulate a ~/.dbus-keyrings symlink to cause a DBusServer with a different uid to     read and write in unintended locations. In the worst case, this could result in the DBusServer reusing a     cookie that is known to the malicious client, and treating that cookie as evidence that a subsequent     client connection came from an attacker-chosen uid, allowing authentication bypass. (CVE-2019-12749)

  - 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)

  - 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.

(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)

(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)

Updated dbus packages fix multiple vulnerabilities :

A denial of service vulnerability in D-Bus before 1.6.20 allows a local attacker to cause a bus-activated service that is not currently running to attempt to start, and fail, denying other users access to this service Additionally, in highly unusual environments the same flaw could lead to a side channel between processes that should not be able to communicate (CVE-2014-3477).

A flaw was reported in D-Bus's file descriptor passing feature. A local attacker could use this flaw to cause a service or application to disconnect from the bus, typically resulting in that service or application exiting (CVE-2014-3532).

A flaw was reported in D-Bus's file descriptor passing feature. A local attacker could use this flaw to cause an invalid file descriptor to be forwarded to a service or application, causing it to disconnect from the bus, typically resulting in that service or application exiting (CVE-2014-3533).

On 64-bit platforms, file descriptor passing could be abused by local users to cause heap corruption in dbus-daemon, leading to a crash, or potentially to arbitrary code execution (CVE-2014-3635).

A denial-of-service vulnerability in dbus-daemon allowed local attackers to prevent new connections to dbus-daemon, or disconnect existing clients, by exhausting descriptor limits (CVE-2014-3636).

Malicious local users could create D-Bus connections to dbus-daemon which could not be terminated by killing the participating processes, resulting in a denial-of-service vulnerability (CVE-2014-3637).

dbus-daemon suffered from a denial-of-service vulnerability in the code which tracks which messages expect a reply, allowing local attackers to reduce the performance of dbus-daemon (CVE-2014-3638).

dbus-daemon did not properly reject malicious connections from local users, resulting in a denial-of-service vulnerability (CVE-2014-3639).

The patch issued by the D-Bus maintainers for CVE-2014-3636 was based on incorrect reasoning, and does not fully prevent the attack described as CVE-2014-3636 part A, which is repeated below. Preventing that attack requires raising the system dbus-daemon's RLIMIT_NOFILE (ulimit -n) to a higher value.

By queuing up the maximum allowed number of fds, a malicious sender could reach the system dbus-daemon's RLIMIT_NOFILE (ulimit -n, typically 1024 on Linux). This would act as a denial of service in two ways :

  - new clients would be unable to connect to the     dbus-daemon

  - when receiving a subsequent message from a non-malicious     client that contained a fd, dbus-daemon would receive     the MSG_CTRUNC flag, indicating that the list of fds was     truncated; kernel fd-passing APIs do not provide any way     to recover from that, so dbus-daemon responds to     MSG_CTRUNC by disconnecting the sender, causing denial     of service to that sender.

This update resolves the issue (CVE-2014-7824).

non-systemd processes can make dbus-daemon think systemd failed to activate a system service, resulting in an error reply back to the requester, causing a local denial of service (CVE-2015-0245).

The remote host is affected by the vulnerability described in GLSA-201412-12 (D-Bus: Multiple Vulnerabilities)

    Multiple vulnerabilities have been discovered in D-Bus. Please review       the CVE identifiers referenced below for details.
  Impact :

    A local attacker could possibly cause a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

The DBUS-1 service and libraries were updated to upstream release 1.6.24 fixing security issues and bugs.

Upstream changes since dbus 1.6.8

  + Security fixes

  - Do not accept an extra fd in the padding of a cmsg     message, which could lead to a 4-byte heap buffer     overrun. (CVE-2014-3635, fdo#83622; Simon McVittie)

  - Reduce default for maximum Unix file descriptors passed     per message from 1024 to 16, preventing a uid with the     default maximum number of connections from exhausting     the system bus' file descriptors under Linux's default     rlimit. Distributors or system administrators with a     more restrictive fd limit may wish to reduce these     limits further. Additionally, on Linux this prevents a     second denial of service in which the dbus-daemon can be     made to exceed the maximum number of fds per sendmsg()     and disconnect the process that would have received     them. (CVE-2014-3636, fdo#82820; Alban Crequy)

  - Disconnect connections that still have a fd pending     unmarshalling after a new configurable limit,     pending_fd_timeout (defaulting to 150 seconds), removing     the possibility of creating an abusive connection that     cannot be disconnected by setting up a circular     reference to a connection's file descriptor.
    (CVE-2014-3637, fdo#80559; Alban Crequy)

  - Reduce default for maximum pending replies per     connection from 8192 to 128, mitigating an algorithmic     complexity denial-of-service attack (CVE-2014-3638,     fdo#81053; Alban Crequy)

  - Reduce default for authentication timeout on the system     bus from 30 seconds to 5 seconds, avoiding denial of     service by using up all unauthenticated connection     slots; and when all unauthenticated connection slots are     used up, make new connection attempts block instead of     disconnecting them. (CVE-2014-3639, fdo#80919; Alban     Crequy)

  - On Linux >= 2.6.37-rc4, if sendmsg() fails with     ETOOMANYREFS, silently drop the message. This prevents     an attack in which a malicious client can make     dbus-daemon disconnect a system service, which is a     local denial of service. (fdo#80163, CVE-2014-3532;
    Alban Crequy)

  - Track remaining Unix file descriptors correctly when     more than one message in quick succession contains fds.
    This prevents another attack which a malicious client     can make dbus-daemon disconnect a system service.
    (fdo#79694, fdo#80469, CVE-2014-3533; Alejandro     Mart&iacute;nez Su&aacute;rez, Simon McVittie, Alban     Crequy)

  - Alban Crequy at Collabora Ltd. discovered and fixed a     denial-of-service flaw in dbus-daemon, part of the     reference implementation of D-Bus. Additionally, in     highly unusual environments the same flaw could lead to     a side channel between processes that should not be able     to communicate. (CVE-2014-3477, fdo#78979)

  - Don't leak temporary fds pointing to /dev/null     (fdo#56927, Michel HERMIER)

  - Create session.d, system.d directories under CMake     (fdo#41319, Ralf Habacker)

  - Include alloca.h for alloca() if available, fixing     compilation on Solaris 10 (fdo#63071, Dagobert     Michelsen)

DBUS-1 was upgraded to upstream release 1.8.

This brings the version of dbus to the latest stable release from an unstable snapshot 1.7.4 that is know to have several regressions

  - Upstream changes since 1.7.4 :

  + Security fixes :

  - Do not accept an extra fd in the padding of a cmsg     message, which could lead to a 4-byte heap buffer     overrun. (CVE-2014-3635, fdo#83622; Simon McVittie)

  - Reduce default for maximum Unix file descriptors passed     per message from 1024 to 16, preventing a uid with the     default maximum number of connections from exhausting     the system bus' file descriptors under Linux's default     rlimit. Distributors or system administrators with a     restrictive fd limit may wish to reduce these limits     further. Additionally, on Linux this prevents a second     denial of service in which the dbus-daemon can be made     to exceed the maximum number of fds per sendmsg() and     disconnect the process that would have received them.
    (CVE-2014-3636, fdo#82820; Alban Crequy)

  - Disconnect connections that still have a fd pending     unmarshalling after a new configurable limit,     pending_fd_timeout (defaulting to 150 seconds), removing     the possibility of creating an abusive connection that     cannot be disconnected by setting up a circular     reference to a connection's file descriptor.
    (CVE-2014-3637, fdo#80559; Alban Crequy)

  - Reduce default for maximum pending replies per     connection from 8192 to 128, mitigating an algorithmic     complexity denial-of-service attack (CVE-2014-3638,     fdo#81053; Alban Crequy)

  - Reduce default for authentication timeout on the system     bus from 30 seconds to 5 seconds, avoiding denial of     service by using up all unauthenticated connection     slots; and when all unauthenticated connection slots are     used up, make new connection attempts block instead of     disconnecting them. (CVE-2014-3639, fdo#80919; Alban     Crequy)

  - On Linux >0 2.6.37-rc4, if sendmsg() fails with     ETOOMANYREFS, silently drop the message. This prevents     an attack in which a malicious client can make     dbus-daemon disconnect a system service, which is a     local denial of service. (fdo#80163, CVE-2014-3532;
    Alban Crequy)

  - Track remaining Unix file descriptors correctly when     more than one message in quick succession contains fds.
    This prevents another attack in which a malicious client     can make dbus-daemon disconnect a system service.
    (fdo#79694, fdo#80469, CVE-2014-3533; Alejandro     Mart&iacute;nez Su&aacute;rez, Simon McVittie, Alban     Crequy)

  - Alban Crequy at Collabora Ltd. discovered and fixed a     denial-of-service flaw in dbus-daemon, part of the     reference implementation of D-Bus. Additionally, in     highly unusual environments the same flaw could lead to     a side channel between processes that should not be able     to communicate. (CVE-2014-3477, fdo#78979)

  + Other fixes and enhancements :

  - Check for libsystemd from systemd >= 209, falling back     to the older separate libraries if not found (Umut     Tezduyar Lindskog, Simon McVittie)

  - On Linux, use prctl() to disable core dumps from a test     executable that deliberately raises SIGSEGV to test     dbus-daemon's handling of that condition (fdo#83772,     Simon McVittie)

  - Fix compilation with --enable-stats (fdo#81043, Gentoo     #507232; Alban Crequy)

  - Improve documentation for running tests on Windows     (fdo#41252, Ralf Habacker)

  - When dbus-launch --exit-with-session starts a     dbus-daemon but then cannot attach to a session, kill     the dbus-daemon as intended (fdo#74698,     &#x420;&#x43E;&#x43C;&#x430;&#x43D;
    &#x414;&#x43E;&#x43D;&#x447;&#x435;&#x43D;&#x43A;&#x43E;
    )

  - in the CMake build system, add some hints for Linux     users cross-compiling Windows D-Bus binaries to be able     to run tests under Wine (fdo#41252, Ralf Habacker)

  - add Documentation key to dbus.service (fdo#77447,     Cameron Norman)

  - in 'dbus-uuidgen --ensure', try to copy systemd's     /etc/machine-id to /var/lib/dbus/machine-id instead of     generating an entirely new ID (fdo#77941, Simon     McVittie)

  - if dbus-launch receives an X error very quickly, do not     kill unrelated processes (fdo#74698,     &#x420;&#x43E;&#x43C;&#x430;&#x43D;
    &#x414;&#x43E;&#x43D;&#x447;&#x435;&#x43D;&#x43A;&#x43E;
    )

  - on Windows, allow up to 8K connections to the     dbus-daemon, instead of the previous 64 (fdo#71297;
    Cristian Onet, Ralf Habacker)

  - cope with \r\n newlines in regression tests, since on     Windows, dbus-daemon.exe uses text mode (fdo#75863,     &#x420;&#x443;&#x441;&#x43B;&#x430;&#x43D;
    &#x418;&#x436;&#x431;&#x443;&#x43B;&#x430;&#x442;&#x43E;
    &#x432;)

  - Enhance the CMake build system to check for GLib and     compile/run a subset of the regression tests (fdo#41252,     fdo#73495; Ralf Habacker)

  - don't rely on va_copy(), use DBUS_VA_COPY() wrapper     (fdo#72840, Ralf Habacker)

  - fix compilation of systemd journal support on older     systemd versions where sd-journal.h doesn't include     syslog.h (fdo#73455, Ralf Habacker)

  - fix compilation on older MSVC versions by including     stdlib.h (fdo#73455, Ralf Habacker)

  - Allow <allow_anonymous/> to appear in an included     configuration file (fdo#73475, Matt Hoosier)

  - If the tests crash with an assertion failure, they no     longer default to blocking for a debugger to be     attached. Set DBUS_BLOCK_ON_ABORT in the environment if     you want the old behaviour.

  - To improve debuggability, the dbus-daemon and     dbus-daemon-eavesdrop tests can be run with an external     dbus-daemon by setting DBUS_TEST_DAEMON_ADDRESS in the     environment. Test-cases that require an     unusually-configured dbus-daemon are skipped.

  - don't require messages with no INTERFACE to be     dispatched (fdo#68597, Simon McVittie)

  - document 'tcp:bind=...' and 'nonce-tcp:bind=...'     (fdo#72301, Chengwei Yang)

  - define 'listenable' and 'connectable' addresses, and     discuss the difference (fdo#61303, Simon McVittie)

  - support printing Unix file descriptors in dbus-send,     dbus-monitor (fdo#70592, Robert Ancell)

  - don't install systemd units if --disable-systemd is     given (fdo#71818, Chengwei Yang)

  - don't leak memory on out-of-memory while listing     activatable or active services (fdo#71526, Radoslaw     Pajak)

  - fix undefined behaviour in a regression test (fdo#69924,     DreamNik)

  - escape Unix socket addresses correctly (fdo#46013,     Chengwei Yang)

  - on SELinux systems, don't assume that SECCLASS_DBUS,     DBUS__ACQUIRE_SVC and DBUS__SEND_MSG are numerically     equal to their values in the reference policy     (fdo#88719, osmond sun)

  - define PROCESS_QUERY_LIMITED_INFORMATION if missing from     MinGW < 4 headers (fdo#71366, Matt Fischer)

  - define WIN32_LEAN_AND_MEAN to avoid conflicts between     winsock.h and winsock2.h (fdo#71405, Matt Fischer)

  - do not return failure from _dbus_read_nonce() with no     error set, preventing a potential crash (fdo#72298,     Chengwei Yang)

  - on BSD systems, avoid some O(1)-per-process memory and     fd leaks in kqueue, preventing test failures (fdo#69332,     fdo#72213; Chengwei Yang)

  - fix warning spam on Hurd by not trying to set     SO_REUSEADDR on Unix sockets, which doesn't do anything     anyway on at least Linux and FreeBSD (fdo#69492, Simon     McVittie)

  - fix use of TCP sockets on FreeBSD and Hurd by tolerating     EINVAL from sendmsg() with SCM_CREDS (retrying with     plain send()), and looking for credentials more     correctly (fdo#69492, Simon McVittie)

  - ensure that tests run with a temporary XDG_RUNTIME_DIR     to avoid getting mixed up in XDG/systemd 'user sessions'     (fdo#61301, Simon McVittie)

  - refresh cached policy rules for existing connections     when bus configuration changes (fdo#39463, Chengwei     Yang)

  - If systemd support is enabled, libsystemd-journal is now     required.

  - When activating a non-systemd service under systemd,     annotate its stdout/stderr with its bus name in the     Journal. Known limitation: because the socket is opened     before forking, the process will still be logged as if     it had dbus-daemon's process ID and user ID. (fdo#68559,     Chengwei Yang)

  - Document more configuration elements in dbus-daemon(1)     (fdo#69125, Chengwei Yang)

  - Don't leak string arrays or fds if     dbus_message_iter_get_args_valist() unpacks them and     then encounters an error (fdo#21259, Chengwei Yang)

  - If compiled with libaudit, retain CAP_AUDIT_WRITE so we     can write disallowed method calls to the audit log,     fixing a regression in 1.7.6 (fdo#49062, Colin Walters)

  - path_namespace='/' in match rules incorrectly matched     nothing; it now matches everything. (fdo#70799, Simon     McVittie)

  - Directory change notification via dnotify on Linux is no     longer supported; it hadn't compiled successfully since     2010 in any case. If you don't have inotify (Linux) or     kqueue (*BSD), you will need to send SIGHUP to the     dbus-daemon when its configuration changes. (fdo#33001,     Chengwei Yang)

  - Compiling with --disable-userdb-cache is no longer     supported; it didn't work since at least 2008, and would     lead to an extremely slow dbus-daemon even it worked.
    (fdo#15589, fdo#17133, fdo#66947; Chengwei Yang)

  - The DBUS_DISABLE_ASSERTS CMake option didn't actually     disable most assertions. It has been renamed to     DBUS_DISABLE_ASSERT to be consistent with the Autotools     build system. (fdo#66142, Chengwei Yang)

  - --with-valgrind=auto enables Valgrind instrumentation if     and only if valgrind headers are available. The default     is still

    --with-valgrind=no. (fdo#56925, Simon McVittie)

  - Platforms with no 64-bit integer type are no longer     supported. (fdo#65429, Simon McVittie)

  - GNU make is now (documented to be) required. (fdo#48277,     Simon McVittie)

  - Full test coverage no longer requires dbus-glib,     although the tests do not exercise the shared library     (only a static copy) if dbus-glib is missing.
    (fdo#68852, Simon McVittie)

  - D-Bus Specification 0.22

  - Document GetAdtAuditSessionData() and     GetConnectionSELinuxSecurityContext() (fdo#54445, Simon)

  - Fix example .service file (fdo#66481, Chengwei Yang)

  - Don't claim D-Bus is 'low-latency' (lower than what?),     just give factual statements about it supporting async     use (fdo#65141, Justin Lee)

  - Document the contents of .service files, and the fact     that system services' filenames are constrained     (fdo#66608; Simon McVittie, Chengwei Yang)

  - Be thread-safe by default on all platforms, even if     dbus_threads_init_default() has not been called. For     compatibility with older libdbus, library users should     continue to call dbus_threads_init_default(): it is     harmless to do so. (fdo#54972, Simon McVittie)

  - Add GetConnectionCredentials() method (fdo#54445, Simon)

  - New API: dbus_setenv(), a simple wrapper around     setenv(). Note that this is not thread-safe. (fdo#39196,     Simon)

  - Add dbus-send --peer=ADDRESS (connect to a given     peer-to-peer connection, like --address=ADDRESS in     previous versions) and dbus-send --bus=ADDRESS (connect     to a given bus, like dbus-monitor

    --address=ADDRESS). dbus-send --address still exists for     backwards compatibility, but is no longer documented.
    (fdo#48816, Andrey Mazo)

  - 'dbus-daemon --nofork' is allowed on Windows again.
    (fdo#68852, Simon McVittie)

  - Avoid an infinite busy-loop if a signal interrupts     waitpid() (fdo#68945, Simon McVittie)

  - Clean up memory for parent nodes when objects are     unexported (fdo#60176, Thomas Fitzsimmons)

  - Make dbus_connection_set_route_peer_messages(x, FALSE)     behave as documented. Previously, it assumed its second     parameter was TRUE. (fdo#69165, Chengwei Yang)

  - Escape addresses containing non-ASCII characters     correctly (fdo#53499, Chengwei Yang)

  - Document <servicedir> search order correctly (fdo#66994,     Chengwei Yang)

  - Don't crash on 'dbus-send --session / x.y.z' which     regressed in 1.7.4. (fdo#65923, Chengwei Yang)

  - If malloc() returns NULL in _dbus_string_init() or     similar, don't free an invalid pointer if the string is     later freed (fdo#65959, Chengwei Yang)

  - If malloc() returns NULL in dbus_set_error(), don't     va_end() a va_list that was never va_start()ed     (fdo#66300, Chengwei Yang)

  - fix build failure with --enable-stats (fdo#66004,     Chengwei Yang)

  - fix a regression test on platforms with strict alignment     (fdo#67279, Colin Walters)

  - Avoid calling function parameters 'interface' since     certain Windows headers have a namespace-polluting macro     of that name (fdo#66493, Ivan Romanov)

  - Assorted Doxygen fixes (fdo#65755, Chengwei Yang)

  - Various thread-safety improvements to static variables     (fdo#68610, Simon McVittie)

  - Make 'make -j check' work (fdo#68852, Simon McVittie)

  - Fix a NULL pointer dereference on an unlikely error path     (fdo#69327, Sviatoslav Chagaev)

  - Improve valgrind memory pool tracking (fdo#69326,     Sviatoslav Chagaev)

  - Don't over-allocate memory in dbus-monitor (fdo#69329,     Sviatoslav Chagaev)

  - dbus-monitor can monitor dbus-daemon < 1.5.6 again     (fdo#66107, Chengwei Yang)

  - If accept4() fails with EINVAL, as it can on older Linux     kernels with newer glibc, try accept() instead of going     into a busy-loop. (fdo#69026, Chengwei Yang)

  - If socket() or socketpair() fails with EINVAL or     EPROTOTYPE, for instance on Hurd or older Linux with a     new glibc, try without SOCK_CLOEXEC. (fdo#69073; Pino     Toscano, Chengwei Yang)

  - Fix a file descriptor leak on an error code path.
    (fdo#69182, Sviatoslav Chagaev)

  - dbus-run-session: clear some unwanted environment     variables (fdo#39196, Simon)

  - dbus-run-session: compile on FreeBSD (fdo#66197,     Chengwei Yang)

  - Fix compilation if writev() is unavailable (fdo#69409,     Vasiliy Balyasnyy)

  - Remove broken support for LOCAL_CREDS credentials     passing, and document where each credential-passing     scheme is used (fdo#60340, Simon McVittie)

  - Make autogen.sh work on *BSD by not assuming GNU     coreutils functionality fdo#35881, fdo#69787; Chengwei     Yang)

  - dbus-monitor: be portable to NetBSD (fdo#69842, Chengwei     Yang)

  - dbus-launch: stop using non-portable asprintf     (fdo#37849, Simon)

  - Improve error reporting from the setuid activation     helper (fdo#66728, Chengwei Yang)

  - Remove unavailable command-line options from     'dbus-daemon --help' (fdo#42441, Ralf Habacker)

  - Add support for looking up local TCPv4 clients'     credentials on Windows XP via the undocumented     AllocateAndGetTcpExTableFromStack function (fdo#66060,     Ralf Habacker)

  - Fix insufficient dependency-tracking (fdo#68505, Simon     McVittie)

  - Don't include wspiapi.h, fixing a compiler warning     (fdo#68852, Simon McVittie)

  - add DBUS_ENABLE_ASSERT, DBUS_ENABLE_CHECKS for less     confusing conditionals (fdo#66142, Chengwei Yang)

  - improve verbose-mode output (fdo#63047, Colin Walters)

Updated dbus packages fix security vulnerabilities :

A flaw was reported in D-Bus's file descriptor passing feature. A local attacker could use this flaw to cause a service or application to disconnect from the bus, typically resulting in that service or application exiting (CVE-2014-3532).

A flaw was reported in D-Bus's file descriptor passing feature. A local attacker could use this flaw to cause an invalid file descriptor to be forwarded to a service or application, causing it to disconnect from the bus, typically resulting in that service or application exiting (CVE-2014-3533).

CVE-2014-3532 denial of service in file descriptor passing feature

CVE-2014-3533 local denial of service (force system services to exit)

CVE-2014-3532 CVE-2014-3533 bnc#885241 fdo#80163 fdo#79694 fdo#80469

The remote Ubuntu 14.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-2275-1 advisory.

    Alban Crequy discovered that dbus-daemon incorrectly sent AccessDenied errors to the service instead of     the client when enforcing permissions. A local user can use this issue to possibly deny access to the     service. (CVE-2014-3477)

    Alban Crequy discovered that dbus-daemon incorrectly handled certain file descriptors. A local attacker     could use this issue to cause services or clients to disconnect, resulting in a denial of service.
    (CVE-2014-3532, CVE-2014-3533)

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

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

- Backport patches from dbus-1.6

    - Fixes CVE-2014-3477 (fd.o#78979)

    - Fixes CVE-2014-3532 (fd.o#80163)

    - Fixes CVE-2014-3533 (fd.o#80469)

    - Resolves #1115636

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Simon McVittie reports :

Alban Crequy at Collabora Ltd. discovered a bug in dbus-daemon's support for file descriptor passing. A malicious process could force system services or user applications to be disconnected from the D-Bus system bus by sending them a message containing a file descriptor, then causing that file descriptor to exceed the kernel's maximum recursion depth (itself introduced to fix a DoS) before dbus-daemon forwards the message to the victim process. Most services and applications exit when disconnected from the system bus, leading to a denial of service.

Additionally, Alban discovered that bug fd.o#79694, a bug previously reported by Alejandro Martinez Suarez which was n believed to be security flaw, could be used for a similar denial of service, by causing dbus-daemon to attempt to forward invalid file descriptors to a victim process when file descriptors become associated with the wrong message.

Several vulnerabilities have been discovered in dbus, an asynchronous inter-process communication system. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2014-3477     Alban Crequy at Collabora Ltd. discovered that     dbus-daemon sends an AccessDenied error to the service     instead of a client when the client is prohibited from     accessing the service. A local attacker could use this     flaw to cause a bus-activated service that is not     currently running to attempt to start, and fail, denying     other users access to this service.

  - CVE-2014-3532     Alban Crequy at Collabora Ltd. discovered a bug in     dbus-daemon's support for file descriptor passing. A     malicious process could force system services or user     applications to be disconnected from the D-Bus system by     sending them a message containing a file descriptor,     leading to a denial of service.

  - CVE-2014-3533     Alban Crequy at Collabora Ltd. and Alejandro Martinez     Suarez discovered that a malicious process could force     services to be disconnected from the D-Bus system by     causing dbus-daemon to attempt to forward invalid file     descriptors to a victim process, leading to a denial of     service.
