According to the versions of the tcpdump package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
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 victim must open a specially crafted pcap file. (CVE-2019-1010220)
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-2018-19519)
tcpdump 4.9.2 has a heap-based buffer over-read related to aoe_print in print-aoe.c and lookup_emem in addrtoname.c.(CVE-2017-16808)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
