Description of problem: logwatch.pl base64 encodes multiple segments and concatenates the encoded parts instead of concatenating the segments and then encoding a single text block. This creates imbedded "end" equal signs in the mime block which causes decode errors. Version-Release number of selected component (if applicable): 7.4 How reproducible: Any time any segment but the last has a length not divisible by three and encode = base64 was specified in the logwatch.conf file. Steps to Reproduce: 1. specify encode = base64 in logwatch.conf 2. 3. Actual results: invalid mime block in email. Expected results: valid mime block in email. Additional info:
How can I actually reproduce this? Making some parts not divisible by 3 before encoding them still produces valid output.
Created attachment 1137033 [details] naive fix
The naive fix works for me. Without the fix I get invalid email, with the fix I get valid email. Not knowing perl it is difficult for me to provide a test case.
