0.102.2

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

• 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.
• Updates to the unit test suite to support libcheck 0.13.
• Updates to support autoconf 2.69 and automake 1.15.
