The automatic crash report processing pipeline runs as root and executes ldd on the attacker-controlled ExecutablePath field of a crash file placed in the world-writable /var/crash directory, causing the dynamic loader to load and execute an attacker-supplied audit module specified by the ELF's DT_AUDIT tag. This allows an attacker to execute arbitrary code with root privileges and fully compromise the affected system.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":7.3,"severity":"high","source":"CNA: canonical","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"}],"modifiedAt":1794255283156,"publishedAt":1794255283156,"references":[{"source":"CNA: canonical","tags":["patch"],"url":"https://github.com/canonical/apport/pull/656"},{"source":"CNA: canonical","tags":["patch"],"url":"https://github.com/canonical/apport/commit/bc7cc6a70590d6596e1f96ad74a021f2c598d73d"},{"source":"CNA: canonical","tags":["issue-tracking"],"url":"https://bugs.launchpad.net/ubuntu/+source/apport/+bug/2164767"}],"remediation":[{"kind":"fix","source":"CNA: canonical","text":"The reporting source identifies this reference as a patch.
