  CVE-2017-12374
  1. ClamAV UAF (use-after-free) Vulnerabilities

  The ClamAV AntiVirus software versions 0.99.2 and prior contain a
  vulnerability that could allow an unauthenticated, remote attacker to
  cause a denial of service (DoS) condition on an affected device.

  The vulnerability is due to a lack of input validation checking
  mechanisms during certain mail parsing operations. If successfully
  exploited, the ClamAV software could allow a variable pointing to the
  mail body which could cause a used after being free (use-after-free)
  instance which may lead to a disruption of services on an affected
  device to include a denial of service condition.

  CVE-2017-12375
  2. ClamAV Buffer Overflow Vulnerability

  The ClamAV AntiVirus software versions 0.99.2 and prior contain a
  vulnerability that could allow an unauthenticated, remote attacker to
  cause a denial of service (DoS) condition on an affected device.

  The vulnerability is due to a lack of input validation checking
  mechanisms during certain mail parsing functions. An unauthenticated,
  remote attacker could exploit this vulnerability by sending a crafted
  email to the affected device. This action could cause a buffer
  overflow condition when ClamAV scans the malicious email, allowing the
  attacker to potentially cause a DoS condition on an affected device.

  CVE-2017-12376
  3. ClamAV Buffer Overflow in handle_pdfname Vulnerability

  ClamAV AntiVirus software versions 0.99.2 and prior contain a
  vulnerability that could allow an unauthenticated, remote attacker to
  cause a denial of service (DoS) condition or potentially execute
  arbitrary code on an affected device.

  The vulnerability is due to improper input validation checking
  mechanisms when handling Portable Document Format (.pdf) files sent to
  an affected device. An unauthenticated, remote attacker could exploit
  this vulnerability by sending a crafted .pdf file to an affected
  device. This action could cause a buffer overflow when ClamAV scans
  the malicious file, allowing the attacker to cause a DoS condition or
  potentially execute arbitrary code.

  CVE-2017-12377
  4. ClamAV Mew Packet Heap Overflow Vulnerability

  ClamAV AntiVirus software versions 0.99.2 and prior contain a
  vulnerability that could allow an unauthenticated, remote attacker to
  cause a denial of service (DoS) condition or potentially execute
  arbitrary code on an affected device.

  The vulnerability is due to improper input validation checking
  mechanisms in mew packet files sent to an affected device. A
  successful exploit could cause a heap overflow condition when ClamAV
  scans the malicious file, allowing the attacker to cause a DoS
  condition or potentially execute arbitrary code on the affected
  device.

  CVE-2017-12378
  5. ClamAV Buffer Over Read Vulnerability

  ClamAV AntiVirus software versions 0.99.2 and prior contain a
  vulnerability that could allow an unauthenticated, remote attacker to
  cause a denial of service (DoS) condition on an affected device.

  The vulnerability is due to improper input validation checking
  mechanisms of .tar (Tape Archive) files sent to an affected device. A
  successful exploit could cause a buffer over-read condition when
  ClamAV scans the malicious .tar file, potentially allowing the
  attacker to cause a DoS condition on the affected device.

  CVE-2017-12379
  6. ClamAV Buffer Overflow in messageAddArgument Vulnerability

  ClamAV AntiVirus software versions 0.99.2 and prior contain a
  vulnerability that could allow an unauthenticated, remote attacker to
  cause a denial of service (DoS) condition or potentially execute
  arbitrary code on an affected device.

  The vulnerability is due to improper input validation checking
  mechanisms in the message parsing function on an affected system. An
  unauthenticated, remote attacker could exploit this vulnerability by
  sending a crafted email to the affected device. This action could
  cause a buffer overflow condition when ClamAV scans the malicious
  email, allowing the attacker to potentially cause a DoS condition or
  execute arbitrary code on an affected device.

  CVE-2017-12380
  7. ClamAV Null Dereference Vulnerability

  ClamAV AntiVirus software versions 0.99.2 and prior contain a
  vulnerability that could allow an unauthenticated, remote attacker to
  cause a denial of service (DoS) condition on an affected device.

  The vulnerability is due to improper input validation checking
  mechanisms during certain mail parsing functions of the ClamAV
  software. An unauthenticated, remote attacker could exploit this
  vulnerability by sending a crafted email to the affected device. An
  exploit could trigger a NULL pointer dereference condition when ClamAV
  scans the malicious email, which may result in a DoS condition.

  CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

  Also included are 2 minor fixes to properly detect openssl install
  locations on FreeBSD 11, and prevent false warnings about zlib 1.2.1#
  version numbers.
