Description Mark J. Cox 2003-06-13 08:44:46 EDT
Paul Szabo discovered that znew, a script included in the gzip
package, creates its temporary files without taking precautions to
avoid a symlink attack (CAN-2003-0367).  gzexe had a similar
vulnerability a while ago, CVE-1999-1332.

Not yet investigated if this affects RHL or which versions.
Comment 1 Jeff Johnson 2003-06-24 16:41:00 EDT
The znew in gzip-1.3.3 does not use /tmp files.
