Libpcap Security Vulnerabilities

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.

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.

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.

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.

CVE-2019-15164

rpcapd/daemon.c in libpcap before 1.9.1 allows SSRF because a URL may be provided as a capture source.

CVE-2019-15165

sf-pcapng.c in libpcap before 1.9.1 does not properly validate the PHB header length before allocating memory.

This ...

CVE-2024-8006
