Descriptions

A flaw was found in the util-linux chfn and chsh utilities when compiled with Readline support. The Readline library uses an "INPUTRC" environment variable to get a path to the library config file. When the library cannot parse the specified file, it prints an error message containing data from the file. This flaw allows an unprivileged user to read root-owned files, potentially leading to privilege escalation. This flaw affects util-linux versions prior to 2.37.4.

Se ha encontrado un fallo en las utilidades chfn y chsh del kernel de Linux cuando son compiladas con soporte para Readline. La biblioteca Readline usa una variable de entorno "INPUTRC" para conseguir una ruta al archivo de configuración de la biblioteca. Cuando la biblioteca no puede analizar el archivo especificado, imprime un mensaje de error que contiene datos del archivo. Este fallo permite a un usuario no privilegiado leer archivos propiedad de root, conllevando potencialmente a una escalada de privilegios. Este fallo afecta a util-linux versiones anteriores a 2.37.4
