Debian DLA-1105-1 : clamav security update

Medium Nessus Plugin ID 103427

Synopsis

The remote Debian host is missing a security update.

Description

clamav is vulnerable to multiple issues that can lead to denial of service when processing untrusted content.

CVE-2017-6418

out-of-bounds read in libclamav/message.c, allowing remote attackers to cause a denial of service via a crafted e-mail message.

CVE-2017-6420

use-after-free in the wwunpack function (libclamav/wwunpack.c), allowing remote attackers to cause a denial of service via a crafted PE file with WWPack compression.

For Debian 7 'Wheezy', these problems have been fixed in version 0.99.2+dfsg-0+deb7u3.

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.

Solution

Upgrade the affected packages.
