"CVE-2017-6419 CVE-2017-11423

Two vulnerabilities have been fixed that can be used for denial of
service or maybe unspecified impact via drafted files (heap-based
buffer overflow and stack-based buffer over-read causing application
crash)

For Debian 7 'Wheezy', these problems have been fixed in version
0.99.2+dfsg-0+deb7u5.

We recommend that you upgrade your clamav packages.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
