security/clamav: update to 0.102.4

Update clamav to 0.102.4.

## 0.102.4

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

- [CVE-2020-3350](https://cve.mitre.org/cgi-bin/cvename.c … -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.

  [RACK911 Lab's \ 
report](https://www.rack911labs.com/research/ex … s-software).

- [CVE-2020-3327](https://cve.mitre.org/cgi-bin/cvename.c … -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](https://cve.mitre.org/cgi-bin/cvename.c … -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.

## 0.102.3

ClamAV 0.102.3 is a bug patch release to address the following issues.

- [CVE-2020-3327](https://cve.mitre.org/cgi-bin/cvename.c … -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.

  Special thanks to Daehui Chang and Fady Othman for helping identify the ARJ
  parsing vulnerability.

- [CVE-2020-3341](https://cve.mitre.org/cgi-bin/cvename.c … -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. Bug found by OSS-Fuzz.

- 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 clamav to 0.102.2.

## 0.102.2

ClamAV 0.102.2 is a bug patch release to address the following issues.

- [CVE-2020-3123](https://cve.mitre.org/cgi-bin/cvename.c … -2020-3123):
  An 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 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-privelege process. This bug was originally fixed in 0.101.2 and the
  fix was mistakenly omitted from 0.102.0.

- Fixed an issue wherein freshclam failed to update if the database version
  downloaded is 1 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 number of kilobytes (KiB) in progress bar and reduced the
  size of the progress bar to accomodate 80-char 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. 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.

- Updates to the unit test suite to support libcheck 0.13.

- Updates to support autoconf 2.69 and automake 1.15.
