| CVE-2011-1935 | Cri | 0.57 | 9.8 | 0.04 | Oct 20, 2017 | 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. | ||
| CVE-2025-11964 | Low | 0.05 | 1.9 | 0.00 | Dec 31, 2025 | On Windows only, if libpcap needs to convert a Windows error message to UTF-8 and the message includes characters that UTF-8 represents using 4 bytes, utf_16le_to_utf_8_truncated() can write data beyond the end of the provided buffer. | ||
| CVE-2025-11961 | Low | 0.05 | 1.9 | 0.00 | Dec 31, 2025 | pcap_ether_aton() is an auxiliary function in libpcap, it takes a string argument and returns a fixed-size allocated buffer. The string argument must be a well-formed MAC-48 address in one of the supported formats, but this requirement has been poorly documented. If an… | ||
| CVE-2024-8006 | Med | 0.00 | 4.4 | 0.00 | Aug 31, 2024 | 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… | ||
| CVE-2023-7256 | Med | 0.00 | 4.4 | 0.00 | Aug 31, 2024 | 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… | ||
| CVE-2019-15165 | Med | 0.00 | 5.3 | 0.03 | Oct 3, 2019 | sf-pcapng.c in libpcap before 1.9.1 does not properly validate the PHB header length before allocating memory. | ||
| CVE-2019-15164 | Med | 0.00 | 5.3 | 0.03 | Oct 3, 2019 | rpcapd/daemon.c in libpcap before 1.9.1 allows SSRF because a URL may be provided as a capture source. | ||
| CVE-2019-15163 | Hig | 0.00 | 7.5 | 0.04 | Oct 3, 2019 | 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. | ||
| CVE-2019-15162 | Med | 0.00 | 5.3 | 0.02 | Oct 3, 2019 | 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. | ||
| CVE-2019-15161 | Med | 0.00 | 5.3 | 0.03 | Oct 3, 2019 | 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. |
