Synopsis

The remote Debian host is missing a security update.

Description

Several vulnerabilities have been found in the ClamAV antivirus toolkit :

CVE-2020-3327

An out of bounds read in the ARJ archive-parsing module could cause denial of service. The fix in 0.102.3 was incomplete.

CVE-2020-3350

A malicious user could trick clamscan, clamdscan or clamonacc into moving or removing a different file than intended when those are used with one of the --move or --remove options. This could be used to get rid of special system files.

CVE-2020-3481

The EGG archive module was vulnerable to denial of service via NULL pointer dereference due to improper error handling. The official signature database avoided this problem because the signatures there avoided the use of the EGG archive parser.

For Debian 9 stretch, these problems have been fixed in version 0.102.4+dfsg-0+deb9u1.

We recommend that you upgrade your clamav packages.

Solution
