Comment 1 Lubomir Kundrak 2007-12-04 08:43:43 UTC

Not vulnerable. These issues did not affect the versions of the zsh package as
shipped with Red Hat Enterprise Linux 2.1, 3, 4, or 5.

Comment 2 James Antill 2007-12-04 13:22:17 UTC

 It's worth noting that even the 4.3.4 version of zsh we ship in Fedora is also
not vulnerable, as we don't ship that perl script (looks like an addon).
