CVSS: 4.4EPSS: 0%CPEs: 1EXPL: 0CVE-2024-8006 – NULL pointer dereference in libpcap before 1.10.5 with remote packet capture support
https://notcve.org/view.php?id=CVE-2024-8006
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. • https://github.com/the-tcpdump-group/libpcap/commit/0f8a103469ce87d2b8d68c5130a46ddb7fb5eb29 https://github.com/the-tcpdump-group/libpcap/commit/8a633ee5b9ecd9d38a587ac9b204e2380713b0d6 • CWE-476: NULL Pointer Dereference •
CVSS: 4.4EPSS: 0%CPEs: 1EXPL: 0CVE-2023-7256 – Double-free in libpcap before 1.10.5 with remote packet capture support.
https://notcve.org/view.php?id=CVE-2023-7256
In affected libpcap versions during the setup of a remote packet capture the internal function sock_initaddress() calls getaddrinfo() and possibly freeaddrinfo(), but does not clearly indicate to the caller function whether freeaddrinfo() still remains to be called after the function returns. This makes it possible in some scenarios that both the function and its caller call freeaddrinfo() for the same allocated memory block. A similar problem was reported in Apple libpcap, to which Apple assigned CVE-2023-40400. • https://github.com/the-tcpdump-group/libpcap/commit/262e4f34979872d822ccedf9f318ed89c4d31c03 https://github.com/the-tcpdump-group/libpcap/commit/2aa69b04d8173b18a0e3492e0c8f2f7fabdf642d • CWE-415: Double Free •

https://notcve.org/view.php?id=CVE-2021-41043
Use after free in tcpslice triggers AddressSanitizer, no other confirmed impact. Un uso de memoria previamente liberada en tcpslice desencadena AddressSanitizer, ningún otro impacto confirmado. A heap use-after-free flaw was found in tcpslices' extract_slice(). This flaw allows an attacker with local network access to pass a specially crafted 'pcap' file to tcpslice, causing segmentation fault. This vulnerability halts or crashes the application, leading to a denial of service. • https://github.com/the-tcpdump-group/tcpslice/issues/11 https://access.redhat.com/security/cve/CVE-2021-41043 https://bugzilla.redhat.com/show_bug.cgi?id=2040392 • CWE-416: Use After Free •
