Changelog: Under certain circumstances, bash will evaluate arithmetic expressions as part of reading an expression token even when evaluation is suppressed. This happens while evaluating a conditional expression and skipping over the failed branch of the expression. There is a race condition in add_history() that can be triggered by a fatal signal arriving between the time the history length is updated and the time the history list update is completed. A later attempt to reference an invalid history entry can cause a crash. Depending on compiler optimizations and behavior, the `read' builtin may not save partial input when a timeout occurs. Subshells begun to run command and process substitutions may attempt to set the terminal's process group to an incorrect value if they receive a fatal signal. This depends on the behavior of the process that starts the shell. MFH: 2017Q1 |
