Comment 4 Dan Williams 2007-09-17 14:27:35 UTC 
I do not believe that any version of Fedora or RHEL is vulnerable due to this
problem, because we do not ship a version of wpa_supplicant that is new enough
to have TSF-related code.  I have quickly checked all other instances of
hexstr2bin and they all appear to be correctly determining the length of the
returned buffer. 

We ship wpa_supplicant 0.5.7 in F-7 and rawhide, 0.4.9 in FC-6, and no version
greater than 0.5.7 in RHEL.  Shall I mark as NOTABUG?
