CVE-2018-14882

Name of the Vulnerable Software and Affected Versions tcpdump versions prior to 4.9.3

Description The issue is related to a buffer over-read in the ICMPv6 parser of the tcpdump utility, which can lead to a denial of service. This can be exploited by a remote attacker. The buffer over-read is located in print-icmp6.c. Additionally, there is a heap-based buffer over-read related to aoe print in print-aoe.c and lookup emem in addrtoname.c.

Recommendations For versions prior to 4.9.3, update to version 4.9.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the ICMPv6 parser and the affected functions aoe print and lookup emem until a patch is available.
