{"id":"UBUNTU-CVE-2024-34397","details":"An issue was discovered in GNOME GLib before 2.78.5, and 2.79.x and 2.80.x before 2.80.1. When a GDBus-based client subscribes to signals from a trusted system service such as NetworkManager on a shared computer, other users of the same computer can send spoofed D-Bus signals that the GDBus-based client will wrongly interpret as having been sent by the trusted system service. This could lead to the GDBus-based client behaving incorrectly, with an application-dependent impact.","modified":"2026-04-22T14:50:43.882255Z","published":"2024-05-07T00:00:00Z","related":["USN-6768-1"],"upstream":["CVE-2024-34397"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2024-34397"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2024-34397"},{"type":"REPORT","url":"https://discourse.gnome.org/t/security-fixes-for-signal-handling-in-gdbus-in-glib/20882/1"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-6768-1"}],"affected":[{"package":{"name":"glib2.0","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/glib2.0@2.40.2-0ubuntu1.1+esm7?arch=source&distro=esm-infra-legacy/trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.38.0-1ubuntu1","2.38.1-1","2.39.1-0ubuntu1","2.39.1-0ubuntu2","2.39.1-0ubuntu3","2.39.2-0ubuntu1","2.39.2-0ubuntu2","2.39.3-0ubuntu4","2.39.4-0ubuntu1","2.39.90-0ubuntu1","2.39.91-0ubuntu2","2.39.91-0ubuntu3","2.39.92-2","2.40.0-1","2.40.0-1ubuntu1","2.40.0-2","2.40.2-0ubuntu1","2.40.2-0ubuntu1.1","2.40.2-0ubuntu1.1+esm1","2.40.2-0ubuntu1.1+esm2","2.40.2-0ubuntu1.1+esm3","2.40.2-0ubuntu1.1+esm4","2.40.2-0ubuntu1.1+esm6","2.40.2-0ubuntu1.1+esm7"],"ecosystem_specific":{"binaries":[{"binary_version":"2.40.2-0ubuntu1.1+esm7","binary_name":"libglib2.0-0"},{"binary_version":"2.40.2-0ubuntu1.1+esm7","binary_name":"libglib2.0-0-refdbg"},{"binary_version":"2.40.2-0ubuntu1.1+esm7","binary_name":"libglib2.0-bin"},{"binary_version":"2.40.2-0ubuntu1.1+esm7","binary_name":"libglib2.0-data"},{"binary_version":"2.40.2-0ubuntu1.1+esm7","binary_name":"libglib2.0-tests"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-34397.json"}},{"package":{"name":"glib2.0","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/glib2.0@2.48.2-0ubuntu4.8+esm5?arch=source&distro=esm-infra/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.46.1-1","2.46.1-2","2.47.1-1","2.47.3-3","2.47.4-1","2.47.5-1","2.47.6-1","2.48.0-1ubuntu3","2.48.0-1ubuntu4","2.48.1-1~ubuntu16.04.1","2.48.2-0ubuntu1","2.48.2-0ubuntu3","2.48.2-0ubuntu4","2.48.2-0ubuntu4.1","2.48.2-0ubuntu4.2","2.48.2-0ubuntu4.3","2.48.2-0ubuntu4.4","2.48.2-0ubuntu4.5","2.48.2-0ubuntu4.6","2.48.2-0ubuntu4.7","2.48.2-0ubuntu4.8","2.48.2-0ubuntu4.8+esm1","2.48.2-0ubuntu4.8+esm3","2.48.2-0ubuntu4.8+esm4","2.48.2-0ubuntu4.8+esm5"],"ecosystem_specific":{"binaries":[{"binary_version":"2.48.2-0ubuntu4.8+esm5","binary_name":"libglib2.0-0"},{"binary_version":"2.48.2-0ubuntu4.8+esm5","binary_name":"libglib2.0-0-refdbg"},{"binary_version":"2.48.2-0ubuntu4.8+esm5","binary_name":"libglib2.0-bin"},{"binary_version":"2.48.2-0ubuntu4.8+esm5","binary_name":"libglib2.0-data"},{"binary_version":"2.48.2-0ubuntu4.8+esm5","binary_name":"libglib2.0-tests"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-34397.json"}},{"package":{"name":"glib2.0","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/glib2.0@2.56.4-0ubuntu0.18.04.9+esm5?arch=source&distro=esm-infra/bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.54.1-1ubuntu1","2.55.2-2ubuntu1","2.56.0-2ubuntu1","2.56.0-4ubuntu1","2.56.1-2ubuntu1","2.56.2-0ubuntu0.18.04.1","2.56.2-0ubuntu0.18.04.2","2.56.3-0ubuntu0.18.04.1","2.56.4-0ubuntu0.18.04.2","2.56.4-0ubuntu0.18.04.3","2.56.4-0ubuntu0.18.04.4","2.56.4-0ubuntu0.18.04.5","2.56.4-0ubuntu0.18.04.6","2.56.4-0ubuntu0.18.04.7","2.56.4-0ubuntu0.18.04.8","2.56.4-0ubuntu0.18.04.9","2.56.4-0ubuntu0.18.04.9+esm3","2.56.4-0ubuntu0.18.04.9+esm4","2.56.4-0ubuntu0.18.04.9+esm5"],"ecosystem_specific":{"binaries":[{"binary_version":"2.56.4-0ubuntu0.18.04.9+esm5","binary_name":"libglib2.0-0"},{"binary_version":"2.56.4-0ubuntu0.18.04.9+esm5","binary_name":"libglib2.0-bin"},{"binary_version":"2.56.4-0ubuntu0.18.04.9+esm5","binary_name":"libglib2.0-data"},{"binary_version":"2.56.4-0ubuntu0.18.04.9+esm5","binary_name":"libglib2.0-dev-bin"},{"binary_version":"2.56.4-0ubuntu0.18.04.9+esm5","binary_name":"libglib2.0-tests"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-34397.json"}},{"package":{"name":"glib2.0","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/glib2.0@2.64.6-1~ubuntu20.04.7?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.64.6-1~ubuntu20.04.7"}]}],"versions":["2.62.1-1","2.63.1-2","2.63.1-2ubuntu1","2.63.3-1","2.63.3-3","2.63.5-2","2.64.0-1","2.64.1-1","2.64.2-1~fakesync1","2.64.3-1~ubuntu20.04.1","2.64.6-1~ubuntu20.04.1","2.64.6-1~ubuntu20.04.2","2.64.6-1~ubuntu20.04.3","2.64.6-1~ubuntu20.04.4","2.64.6-1~ubuntu20.04.6"],"ecosystem_specific":{"availability":"No
