CVE-2026-35348

Full vulnerability record from the local CVENow database.

Description

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.

      "value": "La utilidad “sort” en “uutils coreutils” es vulnerable a un pánico de proceso al usar la opción “--files0-from” con entradas que contienen nombres de archivo que no son UTF-8. La implementación fuerza la codificación UTF-8 y utiliza “expect()”, causando una caída inmediata al encontrar rutas válidas pero que no son UTF-8. Esto difiere de “GNU sort”, que trata los nombres de archivo como bytes sin procesar. Un atacante local puede explotar esto para hacer que la utilidad falle y perturbar los pipelines automatizados."
