Monthly
The crash reporting feature in Apport 2.13 through 2.17.x before 2.17.1 allows local users to gain privileges via a crafted usr/share/apport/apport file in a namespace (container). Rated high severity (CVSS 7.2), this vulnerability is low attack complexity. Public exploit code available and EPSS exploitation probability 19.1%.
Path traversal in the `apport-unpack` utility of Canonical Apport enables arbitrary file creation and overwrite by exploiting attacker-controlled key names embedded in crafted crash report files. Affected versions span all Apport releases before 2.28.4, 2.34.2, and 2.36.0 - software that ships by default with Ubuntu desktop and server editions. An attacker who delivers a malicious `.crash` file and induces a user or automated pipeline to unpack it can write files to any location accessible by the executing user, creating a realistic privilege-escalation primitive on multi-user or developer Ubuntu systems. No public exploit is identified at time of analysis, and the vulnerability is not listed in the CISA KEV catalog.
