Debian Linux Security Advisory 3599-1 – 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.
