CVE-2018-14464

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 LMP parser of the tcpdump utility, specifically in the lmp print data link subobjs() function in print-lmp.c. This can allow a remote attacker to gain unauthorized access to information and impact its integrity and availability. Additionally, it may cause a denial of service. The aoe print function in print-aoe.c and the lookup emem function in addrtoname.c are also related to a heap-based buffer over-read.

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 disabling the lmp print data link subobjs() function until a patch is available. Restrict access to the print-lmp.c module to minimize the risk of exploitation.
