click/install.py in click does not require files in package filesystem tarballs to start with ./ (dot slash), which allows remote attackers to install an alternate security policy and gain privileges via a crafted package, as demonstrated by the test.mmrow app for Ubuntu phone.

Security readout for executives and security teams

CVE-2015-8768 is a flaw in Ubuntu's click package installer. A maliciously crafted package could install a different security policy than intended and gain privileges. The sources tie this to Ubuntu Phone click packages; they do not provide CVSS scoring or a complete affected-version list. Exposure is most likely where Ubuntu click packages are installed or processed, especially Ubuntu Phone-era environments. The bundle does not support treating the unrelated Python Click CLI library as affected. Prioritize if the organization still handles Ubuntu click packages or legacy Ubuntu Phone assets. Otherwise, this is mainly a legacy exposure to document and close during asset review. Mitigation focus: Review Ubuntu USN-2771-1 and related Launchpad guidance for fixed click packages.; Inventory systems that install, build, or validate Ubuntu click packages.; Retire unsupported Ubuntu Phone or click-package handling environments where practical..
