Affected packages
• Go github.com/google/fscrypt: < 0.3.3 → fixed in 0.3.3
Description
The bash completion script for `fscrypt` through v0.3.2 allows injection of commands via crafted mountpoint paths, allowing privilege escalation under a specific set of circumstances. A local user who has control over mountpoint paths could potentially escalate their privileges if they create a malicious mountpoint path and if the system administrator happens to be using the `fscrypt` bash completion script to complete mountpoint paths. We recommend upgrading to v0.3.3 or above.
