: These issues typically stem from classic input sanitization flaws rather than complex memory corruption. The software fails to properly check and clean the file paths contained within the archive.

: Attackers can create malicious .rar archives with specially formatted file paths (e.g., using ..\..\ ). This forces the extraction process to write files outside the intended target directory, potentially into sensitive locations like the %LOCALAPPDATA% or Startup folders.

While recent security disclosures have highlighted newer flaws like , which allows attackers to drop malicious files into system folders using Alternate Data Streams (ADS), technical write-ups often focus on how these archivers handle path sanitization and permissions.
