[clamav-users] Errir parsing PNG files and 451_mail_server_temporarily_rejected_message

[Micah Snyder (micasnyd)]

Hi all,

It seems as though the new PNG graphics format/CVE checker added in 0.103 is causing trouble for you and for some others.  We will disable it for now, which we can do with an update to the daily database.  

Pablo, if you're allowed to share some of the PNG files with me that caused issues for you, the samples will help us find the bug in the PNG parser.

Regards,
Micah

    Hi

    I started seeing the error [ 
    451_mail_server_temporarily_rejected_message ] on maillog, and looking 
    in the clamd.log I found a lot of lines like this [ /*/*/*/*.png: Can't 
    parse data ERROR ]
    I added on clamd.conf the next line

    ExcludePath ^\.png$

    But clamd is still sending the error
    Is there a way to avoid this ?
    Any mail qith a PNG file is rejected by clamd

    My config
    FreeBSD 11.3-RELEASE-p13
    qmail (with a lot ot patches)
    SpamDyke 5.0.1
    ClamAV 0.103.0

    Thanks
