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

Description The issue concerns a buffer over-read in the VRRP parser for VRRP version 3, which occurs in the vrrp print() function in print-vrrp.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 the use of the VRRP parser and aoe print function until a patch is available.
