another environment (CVE-2014-7169 
). With this update prefix and suffix
for environment variable names which contain shell functions are added
as hardening measure.

Additionally two out-of-bounds array accesses in the bash parser are
fixed which were revealed in Red Hat's internal analysis for these
issues and also independently reported by Todd Sabin.");
