CVE-2020-8036 [HIGH] CWE-125 tcpdump: the tok2strbuf function was used by the SOME/IP dissector in an unsafe way
tcpdump: the tok2strbuf function was used by the SOME/IP dissector in an unsafe way
The tok2strbuf() function in tcpdump 4.10.0-PRE-GIT was used by the SOME/IP dissector in an unsafe way.
An out-of-bounds read vulnerability was discovered in tcpdump while printing SOME/IP packets captured in a pcap file or coming from the network. This flaw allows a remote attacker to send specially crafted packets that, when printed, can trigger the flaw and crash the application. The highest threat from this vulnerability is to system availability.
Statement: This issue did not affect the versions of `tcpdump` as shipped with Red Hat Enterprise Linux 5, 6, 7, and 8, as they did not include support for the SOME/IP dissector.
