  clamav:
    Installed: 0.100.2+dfsg-1ubuntu0.18.04.1
    Candidate: 0.100.2+dfsg-1ubuntu0.18.04.1

  
  The current version of ClamAV for 18.04.2 LTS is 0.100.2+dfsg-1ubuntu0.18.04.1. The current stable version of ClamAV is 0.101.2. There have been patches released for 0.101.2 and 0.100.3 that fix security related bugs as shown below:

  ClamAV 0.101.2

  ClamAV 0.101.2 is a patch release to address a handful of security
  related bugs.

  This patch release is being released alongside the 0.100.3 patch so that users
  who are unable to upgrade to 0.101 due to libclamav API changes are protected.

  This release includes 3 extra security related bug fixes that do not apply to
  prior versions.  In addition, it includes a number of minor bug fixes and
  improvements.

  - Fixes for the following vulnerabilities affecting 0.101.1 and prior:
    - 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.

  - Fixes for the following vulnerabilities affecting 0.101.1 and 0.101.0 only:
    - 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. Issue reported by aCaB.
    - CVE-2019-1798:
      A use-after-free condition may occur as a result of improper error
      handling when scanning nested RAR archives. Issue reported by David L.

  - Fixes for the following assorted bugs:
    - Added checks to prevent shifts from causing undefined behavior in HTML
      normalizer, UPX unpacker, ARJ extractor, CPIO extractor, OLE2 parser,
      LZW decompressor used in the PDF parser, Xz decompressor, and UTF-16 to
      ASCII transcoder.
    - Added checks to prevent integer overflow in UPX unpacker.
    - Fix for minor memory leak in OLE2 parser.
    - Fix to speed up PDF parser when handling truncated (or malformed) PDFs.
    - Fix for memory leak in ARJ decoder failure condition.
    - Fix for potential memory and file descriptor leak in HTML normalization code.

  - Removed use of problematic feature that converted file descriptors to
    file paths. The feature was intended to improve performance when scanning
    file types, notably RAR archives, for which the API requires a file path.
    This feature caused issues in environments where the ClamAV engine is run
    in a low-permissions or sandboxed process. RAR archives are still supported
    with this change, but performance may suffer slightly if the file path is not
    provided in calls to `cl_scandesc_callback()`.
    - Added filename and tempfile names to scandesc calls in clamd.
    - Added general scan option `CL_SCAN_GENERAL_UNPRIVILEGED` to treat the scan
      engine as unprivileged, meaning that the scan engine will not have read
      access to the file. Provided file paths are for logging purposes only.
    - Added ability to create a temp file when scanning RAR archives when the
      process does not have read access to the file path provided (i.e.
      unprivileged is set, or an access check fails).

  ClamAV 0.100.3

  ClamAV 0.100.3 is a patch release to address a few security related
  bugs.

  This patch release is being released alongside the 0.101.2 patch so that users
  who are unable to upgrade to 0.101 due to libclamav API changes are protected.

  The bug fixes in this release are limited to security-related bugs only.
  Users are encouraged to upgrade to 0.101.2 for additional improvements.
