The Ubuntu security team deemed this advisory irrelevant for Ubuntu:25.10.
NVD Description
Note: Versions mentioned in the description apply only to the upstream rust-coreutils package and not the rust-coreutils package as distributed by Ubuntu.
The printenv utility in uutils coreutils fails to display environment variables containing invalid UTF-8 byte sequences. While POSIX permits arbitrary bytes in environment strings, the uutils implementation silently skips these entries rather than printing the raw bytes. This vulnerability allows malicious environment variables (e.g., adversarial LD_PRELOAD values) to evade inspection by administrators or security auditing tools, potentially allowing library injection or other environment-based attacks to go undetected.
