Detection & IOCsextracted from sources · hover to see the quote

  • A TAR archive entry with a length field set to the size of that entire entry plus part of the header of the next entry will cause vulnerable TAR parsers to skip scanning the next entry, bypassing malware detection.
  • Malformed/specially-crafted TAR archives can be used to evade AV scanning in ClamAV and many other products; inspect TAR length fields for values that overlap into subsequent entry headers.
  • ·The vulnerability was confirmed present in ClamAV 0.96.4; it is unknown whether versions between 0.96.4 and 0.97.4 are also affected. The fix was introduced in ClamAV 0.97.5.
  • ·This CVE may be split into multiple CVEs in the future if the TAR parser bug is shown to have occurred independently across different vendor implementations.
  • ·The ClamAV 0.97.5 fix package introduced a regression that could cause ClamAV to fail to scan certain documents; a follow-up update was required.
