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.
