Synopsis:	Low: bash security and bug fix update
Issue date:	2011-02-16
CVE Names:	CVE-2008-5374

It was found that certain scripts bundled with the Bash documentation
created temporary files in an insecure way. A malicious, local user 
could use this flaw to conduct a symbolic link attack, allowing them to 
overwrite the contents of arbitrary files accessible to the victim 
running the scripts. (CVE-2008-5374)

This update also fixes the following bugs:

* If a child process's PID was the same as the PID of a previously ended
child process, Bash did not wait for that child process. In some cases 
this caused "Resource temporarily unavailable" errors. With this update, 
Bash recycles PIDs and waits for processes with recycled PIDs. (BZ#521134)

* Bash's built-in "read" command had a memory leak when "read" failed 
due to no input (pipe for stdin). With this update, the memory is 
correctly freed. (BZ#537029)

* Bash did not correctly check for a valid multi-byte string when 
setting the IFS value, causing Bash to crash. With this update, Bash 
checks the multi-byte string and no longer crashes. (BZ#539536)

* Bash incorrectly set locale settings when using the built-in "export"
command and setting the locale on the same line (for example, with
"LC_ALL=C export LC_ALL"). With this update, Bash correctly sets locale
settings. (BZ#539538)
