Marcin Icewall Noga of Cisco Talos discovered an out-of-bound read
vulnerability in the CInArchive::ReadFileItem method in p7zip, a 7zr
file archiver with high compression ratio. A remote attacker can take
advantage of this flaw to cause a denial-of-service or, potentially the
execution of arbitrary code with the privileges of the user running
p7zip, if a specially crafted UDF file is processed.
