Further issue details (http://www.openwall.com/lists/oss-security/2013/04/27/3):
--------------------------------------------------------------------------------
Hi,

sorry for the delayed response, I'm OOO.

The bugs should be public now:

https://bugzilla.clamav.net/show_bug.cgi?id=7055
heap corruption, potentially exploitable.

https://bugzilla.clamav.net/show_bug.cgi?id=7053
overflow due to PDF key length computation. Potentially exploitable.

https://bugzilla.clamav.net/show_bug.cgi?id=7054
NULL pointer dereference in sis parsing.

When building clamav I recommend disabling legacy or unneeded features
(e.g. sis). I guess that's common sense though.

Cheers
Felix

This last one is still not public.

Why do you consider, that sis is unwanted? For email scanner any attachment parsing is useful. Even on PC platform user can send an promiscuous .sis file.

Disabling some features can be considered as security bug too, if user knows about features in clamav, but they are disabled in Fedora/EPEL.

According to http://www.openwall.com/lists/oss-security/2013/04/29/12 :

> https://bugzilla.clamav.net/show_bug.cgi?id=7055
> heap corruption, potentially exploitable.

this is CVE-2013-2020
 
> https://bugzilla.clamav.net/show_bug.cgi?id=7053
> overflow due to PDF key length computation. Potentially exploitable.

this is CVE-2013-2021 (the email above has a typo and also says 2020, which is incorrect; a subsequent email will rectify that typo)

> https://bugzilla.clamav.net/show_bug.cgi?id=7054
> NULL pointer dereference in sis parsing.

This bug is still not public, so no CVE assigned as of yet.
