Bash has been updated to version 4.2 patch level 50, which further mitigates
ShellShock-type vulnerabilities. Two such issues have already been discovered
(CVE-2014-6277, CVE-2014-6278).
See the RedHat article on the backward-incompatible changes introduced by the
latest patch, caused by adding prefixes and suffixes to the variable names used
for exporting functions. Note that the RedHat article mentions these variable
names will have parentheses '()' at the end of their names, however, the latest
upstream patch uses two percent signs '%%' at the end instead.
Two other unrelated security issues in the parser have also been fixed in this
update (CVE-2014-7186, CVE-2014-7187).");
