upstream patch (r5389) to correct the issue (untested) none

Description Vincent Danen 2009-08-05 19:18:03 UTC 
Fetchmail suffers from a similar NULL terminator bypass in how it handles SSL certificates, as demonstrated with CVE-2009-2408.

The upstream svn repository [1] has been updated with a currently-untested patch (revision 5389), which I will attach in a moment.
