Bug ID: 7798
Summary: Incorrect call to Encode::decode() in
Mail/SpamAssassin/Message.pm bails scanning of
message.
Product: Spamassassin
Version: 3.4.4
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: P2
Component: Libraries
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: Undefined
There's an incorrect call to the Encode::decode() function in
Mail/SpamAssassin/Message.pm, sub _parse_normal:
| $msg->{'name'} = Encode::decode("MIME-Header", $msg->{'name'});
Resulting in log lines:
| warn: plugin: eval failed: Unknown encoding 'MIME-Header' at
/usr/share/perl5/Mail/SpamAssassin/Message.pm line 1079.
Encode::decode() seems to expect a valid charset as first argument, not a
scalar 'MIME-Header'.
The effect of a message hitting this condition is that it is passed unscanned
as 'Not Spam'.
The part of the offending message that caused this condition, had incorrect
formatting of MIME headers:
