Hi Guys,
after the last job Cron " CLAM antivirus" PDF attachements seems to be blocked.

[*]Clamd: message was infected: Win.Exploit.CVE_2019_0903-6966169-0
Clamd: Check 15 juni 2019.pdf was infected: Win.Exploit.CVE_2019_0903-6966169-0

The issue now is not every PDF is blocked however i am curious if other people are having this issue too or just the file is really explote .CVE.
files are ok on /etc/MailScanner


Thank you

I would trust that message. That PDF may have a virus in it.

Hello,

This seems to be a false positive as I am even getting this from my Spamexperts PDF reports now

I guess a Clamav update in a day or so should resolve it.

There is an issue with clamav pdf's scanning at the moment.

To temp solve it, and don't blame me if the message did report a valid (Win.Exploit.CVE_2019_0903-6966169-0) virus :shhh:

1. Howto whitelist a clamav signature https://www.clamav.net/documents/how-do ... -signature

2. A more detailed ( copy and paste) solution https://marc.info/?l=clamav-users&m=155895964604136&w=2

It would make sense to review your security policy and to check your backup policy, before you whitelist any signatures.

Just take a look at Baltimore https://www.nytimes.com/2019/05/25/us/n ... imore.html
