Security update for clamav

This update for clamav fixes the following issues:

clamav was updated to the new major release 0.103.0. (jsc#ECO-3010,bsc#1118459)

Note that libclamav was changed incompatible, if you have a 3rd party
application that uses libclamav, it needs to be rebuilt.

Update to 0.103.0

* clamd can now reload the signature database without blocking
scanning. This multi-threaded database reload improvement was made
possible thanks to a community effort.

- Non-blocking database reloads are now the default behavior. Some
systems that are more constrained on RAM may need to disable
non-blocking reloads as it will temporarily consume two times as
much memory. We added a new clamd config option
ConcurrentDatabaseReload, which may be set to no.

* Fix clamav-milter.service (requires clamd.service to run)

Update to 0.102.4

* CVE-2020-3350: Fix a vulnerability wherein a malicious user could
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 (eg. a critical system file). The issue would
affect users that use the --move or --remove options for clamscan,
clamdscan, and clamonacc.
* CVE-2020-3327: Fix 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 results in an
out-of-bounds read which could cause a crash. The previous fix for
this CVE in 0.102.3 was incomplete. This fix correctly resolves
the issue.
* CVE-2020-3481: Fix a vulnerability in the EGG archive module in
ClamAV 0.102.0 - 0.102.3 could cause a Denial-of-Service (DoS)
condition. Improper error handling may result in 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 versions affected by the vulnerability.

Update to 0.102.3

* CVE-2020-3327: Fix a vulnerability in the ARJ archive parsing
module in ClamAV 0.102.2 that could cause a Denial-of-Service (DoS)
condition. Improper bounds checking of an unsigned variable results
in an out-of-bounds read which causes a crash.
* CVE-2020-3341: Fix a vulnerability in the PDF parsing module in
ClamAV 0.101 - 0.102.2 that could cause a Denial-of-Service (DoS)
condition. Improper size checking of a buffer used to initialize AES
decryption routines results in an out-of-bounds read which may cause
a crash.
* Fix "Attempt to allocate 0 bytes" error when parsing some PDF
documents.
* Fix a couple of minor memory leaks.
* Updated libclamunrar to UnRAR 5.9.2.

Update to 0.102.2:

* CVE-2020-3123: A denial-of-service (DoS) condition may occur when
using the optional credit card data-loss-prevention (DLP) feature.
Improper bounds checking of an unsigned variable resulted in an
out-of-bounds read, which causes a crash.
* Significantly improved the scan speed of PDF files on Windows.
* Re-applied a fix to alleviate file access issues when scanning RAR
files in downstream projects that use libclamav where the scanning
engine is operating in a low-privilege process. This bug was originally
fixed in 0.101.2 and the fix was mistakenly omitted from 0.102.0.
* Fixed an issue where freshclam failed to update if the database version
downloaded is one version older than advertised. This situation may
occur after a new database version is published. The issue affected
users downloading the whole CVD database file.
* Changed the default freshclam ReceiveTimeout setting to 0 (infinite).
The ReceiveTimeout had caused needless database update failures for
users with slower internet connections.
* Correctly display the number of kilobytes (KiB) in progress bar and
reduced the size of the progress bar to accommodate 80-character width
terminals.
* Fixed an issue where running freshclam manually causes a daemonized
freshclam process to fail when it updates because the manual instance
deletes the temporary download directory. The freshclam temporary files
will now download to a unique directory created at the time of an update
instead of using a hardcoded directory created/destroyed at the program
start/exit.
* Fix for freshclam's OnOutdatedExecute config option.
* Fixes a memory leak in the error condition handling for the email
parser.
* Improved bound checking and error handling in ARJ archive parser.
* Improved error handling in PDF parser.
* Fix for memory leak in byte-compare signature handler.

- The freshclam.service should not be started before the network is
online (it checks for updates immediately upon service start)

Update to 0.102.1:

* CVE-2019-15961, bsc#1157763: A Denial-of-Service (DoS)
vulnerability may occur when scanning a specially crafted email
file as a result of excessively long scan times. The issue is
resolved by implementing several maximums in parsing MIME
messages and by optimizing use of memory allocation.
* Build system fixes to build clamav-milter, to correctly link
with libxml2 when detected, and to correctly detect fanotify
for on-access scanning feature support.
* Signature load time is significantly reduced by changing to a
more efficient algorithm for loading signature patterns and
allocating the AC trie. Patch courtesy of Alberto Wu.
* Introduced a new configure option to statically link libjson-c
with libclamav. Static linking with libjson is highly
recommended to prevent crashes in applications that use
libclamav alongside another JSON parsing library.
* Null-dereference fix in email parser when using the
--gen-json metadata option.
* Fixes for Authenticode parsing and certificate signature
(.crb database) bugs.

Update to 0.102.0:

* The On-Access Scanning feature has been migrated out of clamd
and into a brand new utility named clamonacc. This utility is
similar to clamdscan and clamav-milter in that it acts as a
client to clamd. This separation from clamd means that clamd no
longer needs to run with root privileges while scanning potentially
malicious files. Instead, clamd may drop privileges to run under an
account that does not have super-user. In addition to improving the
security posture of running clamd with On-Access enabled, this
update fixed a few outstanding defects:
- On-Access scanning for created and moved files (Extra-Scanning)
is fixed.
- VirusEvent for On-Access scans is fixed.
- With clamonacc, it is now possible to copy, move, or remove a
file if the scan triggered an alert, just like with clamdscan.
* The freshclam database update utility has undergone a significant
update. This includes:
- Added support for HTTPS.
- Support for database mirrors hosted on ports other than 80.
- Removal of the mirror management feature (mirrors.dat).
- An all new libfreshclam library API.
- created new subpackage libfreshclam2

Update to 0.101.4:

* CVE-2019-12900: An out of bounds write in the NSIS bzip2
(bsc#1149458)
* CVE-2019-12625: Introduce a configurable time limit to mitigate
zip bomb vulnerability completely. Default is 2 minutes,
configurable useing the clamscan --max-scantime and for clamd
using the MaxScanTime config option (bsc#1144504)

Update to version 0.101.3:

* bsc#1144504: ZIP bomb causes extreme CPU spikes

Update to version 0.101.2 (bsc#1130721)

* CVE-2019-1787:
An out-of-bounds heap read condition may occur when scanning PDF
documents. The defect is a failure to correctly keep track of the number
of bytes remaining in a buffer when indexing file data.
* CVE-2019-1789:
An out-of-bounds heap read condition may occur when scanning PE files
(i.e. Windows EXE and DLL files) that have been packed using Aspack as a
result of inadequate bound-checking.
* CVE-2019-1788:
An out-of-bounds heap write condition may occur when scanning OLE2 files
such as Microsoft Office 97-2003 documents. The invalid write happens when
an invalid pointer is mistakenly used to initialize a 32bit integer to
zero. This is likely to crash the application.
* CVE-2019-1786:
An out-of-bounds heap read condition may occur when scanning malformed
PDF documents as a result of improper bounds-checking.
* CVE-2019-1785:
A path-traversal write condition may occur as a result of improper
input validation when scanning RAR archives.
* CVE-2019-1798:
A use-after-free condition may occur as a result of improper error
handling when scanning nested RAR archives.
