CVE-2017-6418

libclamav/message.c in ClamAV 0.99.2 allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted e-mail message.

It was discovered that ClamAV incorrectly handled parsing certain e-mail messages. A remote attacker could possibly use this issue to cause ClamAV to crash, resulting in a denial of service (CVE-2017-6418).

It was discovered that ClamAV incorrectly handled parsing certain PE files with WWPack compression. A remote attacker could possibly use this issue to cause ClamAV to crash, resulting in a denial of service (CVE-2017-6420).

These are all security issues fixed in the clamav-0.103.3-1.4 package on the GA media of openSUSE Tumbleweed.

This update for clamav fixes the following issues:

• Update to security release 0.99.3 (bsc#1077732)

  • CVE-2017-12377 (ClamAV Mew Packet Heap Overflow Vulnerability)
  • CVE-2017-12379 (ClamAV Buffer Overflow in messageAddArgument Vulnerability)
    • these vulnerabilities could have allowed an unauthenticated, remote attacker to cause a denial of service (DoS) condition or potentially execute arbitrary code on an affected device.

  • CVE-2017-6419 (bsc#1052449)
    • ClamAV could have allowed remote attackers to cause a denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a crafted CHM file.
  • CVE-2017-11423 (bsc#1049423)
    • ClamAV could have allowed remote attackers to cause a denial of service (stack-based buffer over-read and application crash) via a crafted CAB file.

It was discovered that ClamAV incorrectly handled certain malformed CHM files. A remote attacker could use this issue to cause ClamAV to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 14.04 LTS. In the default installation, attackers would be isolated by the ClamAV AppArmor profile. (CVE-2017-6419)
