Package : clamav Version : 0.102.4+dfsg-0+deb9u1 CVE ID : CVE-2020-3327 CVE-2020-3350 CVE-2020-3481

Several vulnerabilities have been found in the ClamAV antivirus toolkit:


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


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.


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.
