Detailsinfo

A vulnerability, which was classified as very critical, has been found in Canonical Apport up to 2.36.x. Affected by this issue is an unknown function of the component Crash Report Processing. The manipulation of the argument ExecutablePath with an unknown input leads to a privileges management vulnerability. Using CWE to declare the problem leads to CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. Impacted is confidentiality, integrity, and availability. CVE summarizes:

In apport before 2.37.0, an improper privilege management vulnerability allows an unprivileged local attacker to gain root privileges on systems where automatic crash reporting is enabled. 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.

The advisory is available at github.com. This vulnerability is handled as CVE-2026-84410 since 09/23/2026. The exploitation is known to be easy. Local access is required to approach this attack. Technical details are known, but there is no available exploit. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 11/09/2026). This vulnerability is assigned to T1068 by the MITRE ATT&CK project.

Upgrading to version 2.37.0 eliminates this vulnerability.
