Descriptions

xterm before 375 allows code execution via font ops, e.g., because an OSC 50 response may have Ctrl-g and therefore lead to command execution within the vi line-editing mode of Zsh. NOTE: font ops are not allowed in the xterm default configurations of some Linux distributions.

xterm anterior a 375 permite la ejecución de código mediante operaciones de fuentes, por ejemplo, porque una respuesta OSC 50 puede tener Ctrl-g y, por lo tanto, conducir a la ejecución de comandos dentro del modo de edición de línea vi de Zsh. NOTA: las operaciones de fuentes no están permitidas en las configuraciones predeterminadas de xterm de algunas distribuciones de Linux.

A vulnerability has been found in xterm which could allow for arbitrary code execution. Versions less than 375 are affected.
