| 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 | [email protected] | 4.4 | 0.01% | 2024-08-31 | 2024-09-19 |
| 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 assi | [email protected] | 4.4 | 0.01% | 2024-08-31 | 2024-09-19 |
| CVE-2019-15165 | sf-pcapng.c in libpcap before 1.9.1 does not properly validate the PHB header length before allocating memory. | [email protected] | 5.3 | 3.20% | 2019-10-03 | 2025-12-03 |
| CVE-2019-15164 | rpcapd/daemon.c in libpcap before 1.9.1 allows SSRF because a URL may be provided as a capture source. | [email protected] | 5.3 | 1.88% | 2019-10-03 | 2024-11-21 |
| CVE-2019-15163 | rpcapd/daemon.c in libpcap before 1.9.1 allows attackers to cause a denial of service (NULL pointer dereference and daemon crash) if a crypt() call fails. | [email protected] | 7.5 | 2.11% | 2019-10-03 | 2024-11-21 |
| CVE-2019-15162 | rpcapd/daemon.c in libpcap before 1.9.1 on non-Windows platforms provides details about why authentication failed, which might make it easier for attackers to enumerate valid usernames. | [email protected] | 5.3 | 1.09% | 2019-10-03 | 2024-11-21 |
| CVE-2019-15161 | rpcapd/daemon.c in libpcap before 1.9.1 mishandles certain length values because of reuse of a variable. This may open up an attack vector involving extra data at the end of a request. | [email protected] | 5.3 | 2.86% | 2019-10-03 | 2024-11-21 |
| CVE-2011-1935 | pcap-linux.c in libpcap 1.1.1 before commit ea9432fabdf4b33cbc76d9437200e028f1c47c93 when snaplen is set may truncate packets, which might allow remote attackers to send arbitrary data while avoiding detection via crafted packets. | [email protected] | 9.8 | 1.32% | 2017-10-20 | 2026-05-13 |
