Closed pasikarkkainen closed 1 year ago

pasikarkkainen commented 3 years ago

I tried using ytnef and noticed it crashes trying to parse the winmail.dat tnef file I have..

$ ytnef -v winmail.dat 
Attempting to parse winmail.dat...
Aid Owner: [4] �'cz
Request Response: [2] 
Segmentation fault

this is using the following:

$ rpm -qa | grep ytnef
ytnef-2.6-12.el7.x86_64
libytnef-1.5-14.el7.x86_64

Some more info.. the crashing winmail.dat tnef file in question looks like the following (when checking with "tnefparse" which seems to be able to parse it properly):

$ tnefparse -o winmail.dat  -b

Several crashes have been fixed since that version. Please try out your winmail.dat file on ytnef compiled from the master branch.
