[Pkg-clamav-devel] Bug#888484: clamav: Security release 0.99.3 available

Package: clamav
Version: 0.99.2+dfsg-0+deb8u2
Severity: important
0.99.3 has been released, see http://blog.clamav.net/2018/01/clamav-0993-has-been-released.html.
This fixed a number of overflow bugs, each of which has assigned CVE numbers
due to the potential for denial of service.
We've have started seeing unexpected clamd crashes on a high-traffic mail
system today, though I've been unable to isolate a test case. It's seems like
too much of a coincidence that these crashes start happening the day after a
security release was announced. We've implemented mitigations but an updated
package would be even better.
Cheers!
Rob N.
