JSON

A flaw was found in the libarchive library. An out-of-bounds access in the copy_from_lzss_window_to_unp function in the libarchive/archive_read_support_format_rar.c file can be triggered due to an integer overflow when a specially crafted RAR archive is processed, causing a crash to the application linked to the library and resulting in a denial of service.

Mitigation

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
