UBUNTU-CVE-2024-8006

Vulnerability from osv_ubuntu – Published: 2024-08-31 00:15 – Updated: 2024-08-31 00:15 – Source website

Withdrawn 2025-06-23

Details

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.
