It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2019-12749 in the wild and no public exploit code.\n\nAffected product: Canonical Ubuntu Linux. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2019-12749/ (Markdown: https://insights.sbomify.com/CVE-2019-12749/index.md)","id":"CVE-2019-12749","markdown":"https://insights.sbomify.com/CVE-2019-12749/index.md","name":"CVE-2019-12749","record":{"aliases":["ALPINE-CVE-2019-12749","AZL-6371","DEBIAN-CVE-2019-12749","DLA-1818-1","DSA-4462-1","GHSA-2hpj-v4f4-7g4j","MGASA-2019-0339","RHSA-2019:1726","RHSA-2019:2868","RHSA-2019:2870","RHSA-2019:3707","RHSA-2020:4032","SUSE-SU-2019:14111-1","SUSE-SU-2019:1521-1","SUSE-SU-2019:1591-1","SUSE-SU-2019:1595-1","SUSE-SU-2019:1597-1","SUSE-SU-2019:2820-2","SUSE-SU-2020:1672-1","UBUNTU-CVE-2019-12749","USN-4015-1","USN-4015-2","openSUSE-SU-2019:1604-1","openSUSE-SU-2019:1671-1","openSUSE-SU-2019:1750-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"D-Bus library","requires_auth":"low_privilege","summary":"A symlink mishandling in D-Bus allows attackers to spoof authentication cookies, potentially bypassing authentication and escalating privileges.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"dbus","vendor":"freedesktop"}],"cvss":{"score":7.1,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"}],"description":"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.","ecosystems":["Red Hat:enterprise_linux:6::client","Red Hat:enterprise_linux:6::computenode","Red Hat:enterprise_linux:6::server","Red
