Bug Description

Description: Ubuntu 18.04.4 LTS
Release: 18.04

apt-cache policy clamav
clamav:
  Installed: 0.102.3+dfsg-0ubuntu0.18.04.1
  Candidate: 0.102.3+dfsg-0ubuntu0.18.04.1

The current version of ClamAV for 18.04.4 LTS is 0.102.3+dfsg-0ubuntu0.18.04.1. The current stable version of ClamAV is 0.102.4. There have been patches released that fix security related bugs as shown below:

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

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.

Request that ClamAV be updated to the latest version 0.102.4

The security team may look at this directly, but tagging server-next to follow up in case not.

There appears to be an established process for clamav updates at https://wiki.ubuntu.com/ClamavUpdates but not sure if it also has an SRU exception granted (LP: #191529 makes me think it might).

0.102.4 does indeed appear to be a narrow update with just CVE fixes: https://blog.clamav.net/2020/07/clamav-01024-security-patch-released.html
