Synopsis

The remote Fedora host is missing a security update.

Description

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.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected clamav package.
