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

• CVE-2020-3327: Fixed a vulnerability in the ARJ archive-parsing module in ClamAV 0.102.2 that could cause a denial-of-service condition. Improper bounds checking of an unsigned variable results in an out-of-bounds read which causes a crash.

• CVE-2020-3341: Fixed a vulnerability in the PDF-parsing module in ClamAV 0.101 - 0.102.2 that could cause a denial-of-service 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. OSS-Fuzz discovered this vulnerability.
• Fixed "Attempt to allocate 0 bytes" error when parsing some PDF documents.
• Fixed a couple of minor memory leaks.
• Updated libclamunrar to UnRAR 5.9.2.
