A vulnerability in sudo-rs was discovered, affecting Ubuntu 26.10 systems. The flaw involves improper handling of time-of-check vs time-of-use conditions in sudoedit, allowing local attackers with specific permissions to place files in arbitrary directories and potentially escalate privileges. This issue primarily impacts systems configured for fine-grained sudoedit file editing permissions, which are not the default settings. The vulnerability was addressed in the recent update USN-8708-2, following the earlier advisory USN-8708-1. Users are advised to update their systems to mitigate risks associated with this vulnerability. The affected package version is sudo-rs 0.2.14-1ubuntu4.1. Regular system updates will apply the necessary changes.
