Log Message:
security/clamav: update to 0.103.1

0.103.1 (2021-01-31)

ClamAV 0.103.1 is a patch release with the following fixes and improvements.

Notable changes

* Added a new scan option to alert on broken media (graphics) file formats.
  This feature mitigates the risk of malformed media files intended to
  exploit vulnerabilities in other software.  At present media validation
  exists for JPEG, TIFF, PNG, and GIF files.  To enable this feature, set
  AlertBrokenMedia yes in clamd.conf, or use the --alert-broken-media option
  when using clamscan.  These options are disabled by default in this patch
  release, but may be enabled in a subsequent release.  Application
  developers may enable this scan option by enabling
  CL_SCAN_HEURISTIC_BROKEN_MEDIA for the heuristic scan option bit field.

* Added CL_TYPE_TIFF, CL_TYPE_JPEG types to match GIF, PNG typing behavior.
  BMP and JPEG 2000 files will continue to detect as CL_TYPE_GRAPHICS
  because ClamAV does not yet have BMP or JPEG 2000 format checking
  capabilities.

Bug fixes

* Fixed PNG parser logic bugs that caused an excess of parsing errors and
  fixed a stack exhaustion issue affecting some systems when scanning PNG
  files.  PNG file type detection was disabled via signature database update
  for ClamAV version 0.103.0 to mitigate the effects from these bugs.

* Fixed an issue where PNG and GIF files no longer work with Target:5
  graphics signatures if detected as CL_TYPE_PNG/GIF rather than as
  CL_TYPE_GRAPHICS.  Target types now support up to 10 possible file types
  to make way for additional graphics types in future releases.

* Fixed clamonacc's --fdpass option.

* File descriptor passing (or "fd-passing") is a mechanism by which
  clamonacc and clamdscan may transfer an open file to clamd to scan, even
  if clamd is running as a non-privileged user and wouldn't otherwise have
  read-access to the file.  This enables clamd to scan all files without
  having to run clamd as root.  If possible, clamd should never be run as
  root so as to mitigate the risk in case clamd is somehow compromised while
  scanning malware.

* Interprocess file descriptor passing for clamonacc was broken since
  version 0.102.0 due to a bug introduced by the switch to curl for
  communicating with clamd.  On Linux, passing file descriptors from one
  process to another is handled by the kernel, so we reverted clamonacc to
  use standard system calls for socket communication when fd passing is
  enabled.

* Fixed a clamonacc stack corruption issue on some systems when using an
  older version of libcurl.  Patch courtesy of Emilio Pozuelo Monfort.

* Allow clamscan and clamdscan scans to proceed even if the realpath lookup
  failed.  This alleviates an issue on Windows scanning files hosted on
  file- systems that do not support the GetMappedFileNameW() API such as on
  ImDisk RAM-disks.

* Fixed freshclam --on-update-execute=EXIT_1 temporary directory cleanup
  issue.

* clamd's log output and VirusEvent now provide the scan target's file path
  instead of a file descriptor.  The clamd socket API for submitting a scan
  by FD-passing doesn't include a file path, this feature works by looking
  up the file path by file descriptor.  This feature works on Mac and Linux
  but is not yet implemented for other UNIX operating systems.  FD-passing
  is not available for Windows.

* Fixed an issue where freshclam database validation didn't work correctly
  when run in daemon mode on Linux/Unix.

Other improvements

* Scanning JPEG, TIFF, PNG, and GIF files will no longer return "parse"
  errors when file format validation fails.  Instead, the scan will alert
  with the "Heuristics.Broken.Media" signature prefix and a descriptive
  suffix to indicate the issue, provided that the "alert broken media"
  feature is enabled.

* GIF format validation will no longer fail if the GIF image is missing the
  trailer byte, as this appears to be a relatively common issue in otherwise
  functional GIF files.

* Added a TIFF dynamic configuration (DCONF) option, which was missing.
  This will allow us to disable TIFF format validation via signature
  database update in the event that it proves to be problematic.  This
  feature already exists for many other file types.

 rename gets to my_gets to avoid conflict with fortify/ssp - they use
