CVE-2024-8006
NULL pointer dereference in libpcap before 1.10.5 with remote packet capture support
概要
NULL pointer dereference in libpcap before 1.10.5 with remote packet capture support
原文の説明
取得元が公開している説明をそのまま載せています (多くは英語)。
Remote packet capture support is disabled by default in libpcap. When a user builds libpcap with remote packet capture support enabled, one of the functions that become available is pcap_findalldevs_ex(). One of the function arguments can be a filesystem path, which normally means a directory with input data files. When the specified path cannot be used as a directory, the function receives NULL from opendir(), but does not check the return value and passes the NULL value to readdir(), which causes a NULL pointer derefence.
