Clam AntiVirus is an anti-virus toolkit written from scratch. It is licensed
under GNU GPL2 and uses the virus database from OpenAntiVirus, which is an
another free anti-virus project. In contrast to OpenAntiVirus (which is written
in Java), Clam AntiVirus is written entirely in C and its database is KEPT UP
TO DATE. It also detects polymorphic viruses as well.

security/clamav: update to 0.103.5

0.103.5 (2022-01-12)

ClamAV 0.103.5 is a critical patch release with the following fixes:

* \ 
CVE-2022-20698<https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-20698>:
  Fix for invalid pointer read that may cause a crash. This issue affects
  0.104.1, 0.103.4 and prior when ClamAV is compiled with libjson-c and the
  CL_SCAN_GENERAL_COLLECT_METADATA scan option (the clamscan --gen-json
  option) is enabled.

  Cisco would like to thank Laurent Delosieres of ManoMano for reporting
  this vulnerability.

* Fixed ability to disable the file size limit with libclamav C API, like
  this:

  cl_engine_set_num(engine, CL_ENGINE_MAX_FILESIZE, 0);

  This issue didn't affect ClamD or ClamScan which also can disable the
  limit by setting it to zero using MaxFileSize 0 in clamd.conf for ClamD,
  or clamscan --max-filesize=0 for ClamScan.

  Note: Internally, the max file size is still set to 2 GiB. Disabling the
  limit for a scan will fall back on the internal 2 GiB limitation.

* Increased the maximum line length for ClamAV config files from 512 bytes
  to 1,024 bytes to allow for longer config option strings.

* SigTool: Fix insufficient buffer size for --list-sigs that caused a
  failure when listing a database containing one or more very long
  signatures. This fix was backported from 0.104.

Special thanks to the following for code contributions and bug reports:

security/clamav: update to 0.103.4

ClamAV 0.103.4 is a critical patch release with the following fixes:

- FreshClam:
  - Add a 24-hour cool-down for FreshClam clients that have received an HTTP
    403 (Forbidden) response from the CDN.
    This is to reduce the volume of 403-response data served to blocked
    FreshClam clients that are configured with a tight update-loop.
  - Fixed a bug where FreshClam treats an empty CDIFF as an incremental update
    failure instead of as an intentional request to download the whole CVD.

- ClamDScan: Fix a scan error when broken symlinks are encountered on macOS with
  "FollowDirectorySymlinks" and "FollowFileSymlinks" options \ 
disabled.

- Overhauled the scan recursion / nested archive extraction logic and added new
  limits on embedded file-type recognition performed during the "raw" \ 
scan of
  each file. This limits embedded file-type misidentification and prevents
  detecting embedded file content that is found/extracted and scanned at other
  layers in the scanning process.

- Fix an issue with the FMap module that failed to read from some nested files.

- Fixed an issue where failing to load some rules from a Yara file containing
  multiple rules may cause a crash.

- Fixed assorted compiler warnings.

- Fixed assorted Coverity static code analysis issues.

- Scan limits:
  - Added virus-name suffixes to the alerts that trigger when a scan limit has
    been exceeded. Rather than simply `Heuristics.Limits.Exceeded`, you may now
    see limit-specific virus-names, to include:
    - `Heuristics.Limits.Exceeded.MaxFileSize`
    - `Heuristics.Limits.Exceeded.MaxScanSize`
    - `Heuristics.Limits.Exceeded.MaxFiles`
    - `Heuristics.Limits.Exceeded.MaxRecursion`
    - `Heuristics.Limits.Exceeded.MaxScanTime`
  - Renamed the `Heuristics.Email.ExceedsMax.*` alerts to align with the other
    limit alerts names. These alerts include:
    - `Heuristics.Limits.Exceeded.EmailLineFoldcnt`
    - `Heuristics.Limits.Exceeded.EmailHeaderBytes`
    - `Heuristics.Limits.Exceeded.EmailHeaders`
    - `Heuristics.Limits.Exceeded.EmailMIMEPartsPerMessage`
    - `Heuristics.Limits.Exceeded.EmailMIMEArguments`
  - Fixed an issue where the Email-related scan limits would alert even when the
    "AlertExceedsMax" (`--alert-exceeds-max`) scan option is not enabled.
  - Fixes an issue in the Zip parser where exceeding the "MaxFiles" \ 
limit or
    the "MaxFileSize" limit would abort the scan but would fail to alert.
    The Zip scan limit issues were independently identified and reported by
    Aaron Leliaert and Max Allan.

- Fixed a leak in the Email parser when using the `--gen-json` scan option.

- Fixed an issue where a failure to record metadata in the Email parser when
  using the `--gen-json` scan option could cause the Email parser to abort the
  scan early and fail to extract and scan additional content.

- Fixed a file name memory leak in the Zip parser.

- Fixed an issue where certain signature patterns may cause a crash or cause
  unintended matches on some systems when converting characters to uppercase if
  a UTF-8 unicode single-byte grapheme becomes a multi-byte grapheme.

Other fixes backported from 0.104.0:

- Fixed a crash in programs that use libclamav when the programs don't set a
  callback for the "virus found" event.
  Patch courtesy of Markus Strehle.

- Added checks to the the SIS archive parser to prevent an SIS file entry from
  pointing to the archive, which would result in a loop. This was not an actual
  infinite loop, as ClamAV's scan recursion limit limits the depth of nested
  archive extraction.

- ClamOnAcc: Fixed a socket file descriptor leak that could result in a crash
  when all available file descriptors are exhausted.

- FreshClam: Fixed an issue where FreshClam would download a CVD repeatedly if a
  zero-byte CDIFF is downloaded or if the incremental update failed and if the
  CVD downloaded after that is older than advertised.
  Patch courtesy of Andrew Williams.

- ClamDScan:
  - Fixed a memory leak of the scan target filename when using the
    `--fdpass` or `--stream` options.
  - Fixed an issue where ClamDScan would fail to scan any file after excluding
    a file with the "ExcludePath" option when using when using the \ 
`--multiscan`
    (`-m`) option along with either `--fdpass` or `--stream`.
    Also fixed a memory leak of the accidentally-excluded paths in this case.
  - Fixed a single file path memory leak when using `--fdpass`.
  - Fixed an issue where the "ExcludePath" regex may fail to exclude \ 
absolute
    paths when the scan is invoked with a relative path.

security/clamav: update to 0.103.2

0.103.2 (2021-04-07)

ClamAV 0.103.2 is a security patch release with the following fixes:

* CVE-2021-1386: Fix for UnRAR DLL load privilege escalation.  Affects
  0.103.1 and prior on Windows only.

* CVE-2021-1252: Fix for Excel XLM parser infinite loop.  Affects 0.103.0
  and 0.103.1 only.

* CVE-2021-1404: Fix for PDF parser buffer over-read; possible crash.
  Affects 0.103.0 and 0.103.1 only.

* CVE-2021-1405: Fix for mail parser NULL-dereference crash.  Affects
  0.103.1 and prior.

* Fix possible memory leak in PNG parser.

* Fix ClamOnAcc scan on file-creation race condition so files are scanned
  after their contents are written.

* FreshClam: Deprecate the SafeBrowsing config option.  The SafeBrowsing
  option will no longer do anything.

* For more details, see our blog post from last year about the future of the
  ClamAV Safe Browsing database.

* Tip: If creating and hosting your own safebrowing.gdb database, you can
  use the DatabaseCustomURL option in freshclam.conf to download it.

* FreshClam: Improved HTTP 304, 403, & 429 handling.

* FreshClam: Added back the mirrors.dat file to the database directory.
  This new mirrors.dat file will store:

	- A randomly generated UUID for the FreshClam User-Agent.
	- A retry-after timestamp that so FreshClam won't try to update
          after having received an HTTP 429 response until the Retry-After
          timeout has expired.

* FreshClam will now exit with a failure in daemon mode if an HTTP 403
  (Forbidden) was received, because retrying later won't help any.  The
  FreshClam user will have to take actions to get unblocked.

* Fix the FreshClam mirror-sync issue where a downloaded database is "older
  than the version advertised."

* If a new CVD download gets a version that is older than advertised,
  FreshClam will keep the older version and retry the update so that the
  incremental update process (CDIFF patch process) will update to the latest
  version.
