Detailsinfo

A vulnerability has been found in Uutils coreutils (affected version unknown) and classified as problematic. This vulnerability affects the function expect of the component sort Utility. The manipulation with an unknown input leads to a uncaught exception vulnerability. The CWE definition for the vulnerability is CWE-248. An exception is thrown from a function, but it is not caught. As an impact it is known to affect availability. CVE summarizes:

The sort utility in uutils coreutils is vulnerable to a process panic when using the --files0-from option with inputs containing non-UTF-8 filenames. The implementation enforces UTF-8 encoding and utilizes expect(), causing an immediate crash when encountering valid but non-UTF-8 paths. This diverges from GNU sort, which treats filenames as raw bytes. A local attacker can exploit this to crash the utility and disrupt automated pipelines.
