Summary

The copy_from_lzss_window function in libarchive versions prior to 3.2.1 is susceptible to an out-of-bounds heap read, which can be triggered by processing a specially crafted RAR file. This vulnerability could lead to a denial of service, potentially allowing remote attackers to exploit it by manipulating file inputs, thereby affecting service availability across systems dependent on libarchive for file manipulation.
