Synopsis

The remote FreeBSD host is missing a security-related update.

Description

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.

Solution

Update the affected package.
