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

Description The issue is related to a lack of certain bounds checks in the lmp print data link subobjs() function in print-lmp.c of the tcpdump utility. This can lead to a buffer over-read, potentially allowing a remote attacker to cause a denial of service. 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 lmp print data link subobjs() function until a patch is available. Avoid using the affected functions aoe print and lookup emem in the respective files print-aoe.c and addrtoname.c until the issue is resolved.
