ClamAV 0.102.4 is out now. Users can head over to clamav.net/downloads <https://www.clamav.net/downloads> to download the release materials. 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>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 <https://cve.mitre.org/cgi-bin/cvename.cgi?name=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 <https://cve.mitre.org/cgi-bin/cvename.cgi?name=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. We will be publishing a release candidate for version 0.103.0 in the next couple of weeks.
