CVE-2004-0234
Multiple stack-based buffer overflows in the get_header function in
header.c for LHA 1.14 allow remote attackers or local users to execute
arbitrary code via long directory or file names in an LHA archive,
which triggers the overflow when testing or extracting the archive.

CVE-2004-0235
Multiple directory traversal vulnerabilities in LHA 1.14 allow remote
attackers or local users to create arbitrary files via an LHA archive
containing filenames with (1) .. sequences or (2) absolute pathnames
with double leading slashes ('//absolute/path').");
