Fixed In Version: bash-4.1.2-15.el6_5.3 Doc Type: Bug Fix

Due to the signal handler function calling certain signal-unsafe functions such as malloc(), the Bash shell in some cases became unresponsive after it received a signal. This update ensures that the signal handler no longer calls signal-unsafe functions, which prevents the described bug from occurring.
