CVE-2007-3798 6 Apple, Canonical, Debian and 3 more 7 Mac Os X, Mac Os X Server, Ubuntu Linux and 4 more 2024-10-15 6.8 MEDIUM 9.8 CRITICAL
Integer overflow in print-bgp.c in the BGP dissector in tcpdump 3.9.6 and earlier allows remote attackers to execute arbitrary code via crafted TLVs in a BGP packet, related to an unchecked return value.
CVE-2023-7256 1 Tcpdump 1 Libpcap 2024-09-19 N/A 4.4 MEDIUM
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.
CVE-2024-8006 1 Tcpdump 1 Libpcap 2024-09-19 N/A 4.4 MEDIUM
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.
CVE-2004-0184 1 Tcpdump 1 Tcpdump 2024-02-15 5.0 MEDIUM N/A
Integer underflow in the isakmp_id_print for TCPDUMP 3.8.1 and earlier allows remote attackers to cause a denial of service (crash) via an ISAKMP packet with an Identification payload with a length that becomes less than 8 during byte order conversion, which causes an out-of-bounds read, as demonstrated by the Striker ISAKMP Protocol Test Suite.
CVE-2004-0183 1 Tcpdump 1 Tcpdump 2024-02-15 5.0 MEDIUM N/A
TCPDUMP 3.8.1 and earlier allows remote attackers to cause a denial of service (crash) via ISAKMP packets containing a Delete payload with a large number of SPI's, which causes an out-of-bounds read, as demonstrated by the Striker ISAKMP Protocol Test Suite.
CVE-2023-1801 1 Tcpdump 1 Tcpdump 2023-12-23 N/A 6.5 MEDIUM
The SMB protocol decoder in tcpdump version 4.99.3 can perform an out-of-bounds write when decoding a crafted network packet.
CVE-2020-8037 4 Apple, Debian, Fedoraproject and 1 more 5 Mac Os X, Macos, Debian Linux and 2 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
The ppp decapsulator in tcpdump 4.9.3 can be convinced to allocate a large amount of memory.
CVE-2019-15161 1 Tcpdump 1 Libpcap 2023-11-07 5.0 MEDIUM 5.3 MEDIUM
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-2019-15163 1 Tcpdump 1 Libpcap 2023-11-07 5.0 MEDIUM 7.5 HIGH
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-2019-15166 8 Apple, Canonical, Debian and 5 more 10 Mac Os X, Ubuntu Linux, Debian Linux and 7 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
lmp_print_data_link_subobjs() in print-lmp.c in tcpdump before 4.9.3 lacks certain bounds checks.
CVE-2019-15162 2 Opengroup, Tcpdump 2 Unix, Libpcap 2023-11-07 5.0 MEDIUM 5.3 MEDIUM
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-2019-15165 7 Apple, Canonical, Debian and 4 more 11 Ipados, Iphone Os, Mac Os X and 8 more 2023-11-07 5.0 MEDIUM 5.3 MEDIUM
sf-pcapng.c in libpcap before 1.9.1 does not properly validate the PHB header length before allocating memory.
CVE-2019-15164 1 Tcpdump 1 Libpcap 2023-11-07 5.0 MEDIUM 5.3 MEDIUM
rpcapd/daemon.c in libpcap before 1.9.1 allows SSRF because a URL may be provided as a capture source.
CVE-2019-1010220 1 Tcpdump 1 Tcpdump 2023-11-07 4.3 MEDIUM 3.3 LOW
tcpdump.org tcpdump 4.9.2 is affected by: CWE-126: Buffer Over-read. The impact is: May expose Saved Frame Pointer, Return Address etc. on stack. The component is: line 234: "ND_PRINT((ndo, "%s", buf));", in function named "print_prefix", in "print-hncp.c". The attack vector is: The victim must open a specially crafted pcap file.
CVE-2018-19519 1 Tcpdump 1 Tcpdump 2023-11-07 4.3 MEDIUM 5.5 MEDIUM
In tcpdump 4.9.2, a stack-based buffer over-read exists in the print_prefix function of print-hncp.c via crafted packet data because of missing initialization.
CVE-2018-16228 6 Apple, Debian, Fedoraproject and 3 more 6 Mac Os X, Debian Linux, Fedora and 3 more 2023-11-07 5.0 MEDIUM 7.5 HIGH
