The read_CodersInfo function in archive_read_support_format_7zip.c in libarchive before 3.2.0 allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via a crafted 7z file, related to the _7z_folder struct.
A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit.
