Ethereal (tethereal and gnome ethereal) are currently not compiled as position independant executables (PIE). A number of security issues recently would have been mitigated somewhat by having Ethereal as PIE. This is a request that the next Ethereal update (be it a security update or the next RHEL Update release) be compiled PIE on RHEL4 and RHEL3.
Removing from RHEL3U7Proposed since this will go out in an async Ethereal security update RHSA-2005:687
Yes, I added some fixes so that ethereal and tethereal is now compiled as PIE. The new packages will be added to RHSA-2005:687.
