Topic

Updated bash packages that fix one bug are now available for Red Hat Enterprise
Linux 6.

Description

The GNU Bourne Again shell (Bash) is a shell and command language interpreter
compatible with the Bourne shell (sh). Bash is the default shell for Red Hat
Enterprise Linux.

This update fixes the following bug:

  • When a SIGCHLD signal was received in job control mode and a handler for the

signal was installed, Bash called the trap handler within the signal handler
itself. This was unsafe and could cause Bash to enter a deadlock or to terminate
unexpectedly with a segmentation fault due to memory corruption. With this
update, the trap handler is now called outside of the signal handler, and Bash
no longer enters a deadlock, neither crashes in this scenario. (BZ#814271)

All users of bash are advised to upgrade to these updated packages, which fix
this bug.

Solution

Before applying this update, make sure that all previously-released errata
relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use the Red Hat
