ustix has discovered temporary file bugs in gzexe, zdiff and znew
which could allow a local user to overwrite arbitrary files by
creating specially named symlinks.

afaict, this does not apply to gzip-1.3.3-11 on fc1.  of course that does not
explain why redhat is looking at this issue for RHEL3 and RHEL4...  i guess i'll
keep an eye on any patches that they release.

can someone else confirm/deny this?

CAN-2004-0970 for gzip-1.3.3

This is the only part of the Debian patch that seems to apply to gzip-1.3.3 -
if at all.

Hmm.  Red Hat has already included a hardened version of the script; from

* Fri Oct 26 2001 Trond Eivind Glomsr&#65533;d <teg@redhat.com> 1.3.0-16
- replace tempfile patches with improved ones solar@openwall.com
- Add less to the dependency chain - zless needs it

Can anyone check this out?  Maybe we can close this as NOTABUG.

Yep. Confirmed. This was already fixed.
