NewStart CGSL MAIN 6.06 : dbus Multiple Vulnerabilities (NS-SA-2025-0231)

high Nessus Plugin ID 266270

Synopsis

The remote NewStart CGSL host is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version MAIN 6.06, 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. NOTE: this is due to an incorrect fix for CVE-2008-3834. (CVE-2009-1189)

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

Solution

Upgrade the vulnerable CGSL dbus packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
