Subject: Requesting a CVE id for Trojitá, an e-mail client: Improper Certificate Validation

Hi folks, I would appreciate a Cc on responses as I'm not subscribed to 
this list. I would like to request a CVE for the following vulnerability:


Damian Poddebniak discovered a TLS verification failure (CWE-295) in 
Trojitá [1], a fast Qt IMAP e-mail client. When sending e-mails over SMTP, 
all TLS errors were ignored.


Trojita first gained support for SMTP submission in patch 0083eea5ed [2]. 
Since that commit (May 2009), there's been a FIXME comment in the code that 
SSL errors should be handled properly. Unfortunately, this issue kept 
falling through the cracks and we never re-enabled TLS validation as the 
SMTP backend matured. As a result, outgoing SMTP connections were 
suspectible to a MITM attack, with authentication details including 
passwords and the message content potentially available to attackers.

IMAP connections are not suspectible to this bug.

Affected versions

All versions of Trojita up to and including v0.7 are affected. The fix [3] 
will be included in version v0.8 which will be released once the CVE gets 


Thanks to Damian Poddebniak for reporting [4] this bug.


With kind regards,

Trojitá, a fast Qt IMAP e-mail client --
