   security/clamav: update to 0.102.4

   Update clamav to 0.102.4.

   ## 0.102.4

   ClamAV 0.102.4 is a bug patch release to address the following issues.

   - [CVE-2020-3350](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-3350):
     Fix a vulnerability wherein a malicious user could 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 (eg. a critical system
     file). The issue would affect users that use the --move or --remove options
     for clamscan, clamdscan, and clamonacc.

     [RACK911 Lab's \ 
report](https://www.rack911labs.com/research/exploiting-almost-every-antivirus-software).

   - [CVE-2020-3327](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-3327):
     Fix 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
     results in an out-of-bounds read which could cause a crash.
     The previous fix for this CVE in 0.102.3 was incomplete. This fix correctly
     resolves the issue.

   - [CVE-2020-3481](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-3481):
     Fix a vulnerability in the EGG archive module in ClamAV 0.102.0 - 0.102.3
     could cause a Denial-of-Service (DoS) condition. Improper error handling
     may result in 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 versions affected by the
     vulnerability.
