7.15. bash

Updated bash packages that fix several bugs are now available for Red Hat Enterprise Linux 6.
The bash packages provide the Bash (Bourne-again shell) shell, which is the default shell for Red Hat Enterprise Linux.

Bug Fixes

BZ#1148507
Prior to this update, Bash refused to import previously exported functions whose names contained a hyphen. As a consequence, scripts that used such functions did not work properly, and Bash printed the following error message:
bash: error importing function definition for `BASH_FUNC_function-name'
With this update, Bash accepts hyphens in the names of imported functions.
BZ#1150544, BZ#1155455
Previously, Bash incorrectly parsed function definitions containing a here-document that ended with the end-of-file or end-of-string character. Consequently, Bash accessed an invalid memory segment when the parsed function was copied, and Bash terminated with a segmentation fault. This problem has been fixed. As a result, Bash no longer crashes when the aforementioned function definitions are used.
BZ#1119587
The section in the Bash man page describing the ulimit command did not contain the fact that 512-byte blocks are used for the "-c" and "-f" options in POSIX mode. This information has now been added.
Users of bash are advised to upgrade to these updated packages, which fix these bugs.
