security advisory debian DoS clamav file management issue archive module

Summary

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.

For the detailed security status of clamav please refer to
its security tracker page at:
