clamav -- multiple vulnerabilities

Micah Snyder reports:

CVE-2020-3350

      Fixed a vulnerability a malicious user could exploit to replace
      a scan target's directory with a symlink to another path to trick
      clamscan, clamdscan, or clamonacc into removing or moving a different
      file (such as a critical system file). The issue would affect users
      that use the --move or --remove options for clamscan, clamdscan and
      clamonacc.

CVE-2020-3327

      Fixed a vulnerability in the ARJ archive-parsing module in ClamAV
      0.102.3 that could cause a denial-of-service (DoS) condition.
      Improper bounds checking resulted in an out-of-bounds read that could
      cause a crash. The previous fix for this CVE in version 0.102.3 was
      incomplete. This fix correctly resolves the issue.

CVE-2020-3481

      Fixed a vulnerability in the EGG archive module in ClamAV 0.102.0
      - 0.102.3 that could cause a denial-of-service (DoS) condition.
      Improper error handling could cause a crash due to a NULL pointer
      dereference. This vulnerability is mitigated for those using the
      official ClamAV signature databases because the file type signatures
      in daily.cvd will not enable the EGG archive parser in affected
      versions.
