Summary
radvdump's Route Information Option Parser has a Stack Buffer Overflow
Details

radvd is a router advertisement daemon for IPv6. Prior to version 2.21, the radvdump utility shipped with radvd contains a stack buffer overflow in the Route Information option parser. When processing a crafted ICMPv6 Router Advertisement, print_ff() copies up to 2032 bytes from attacker-controlled packet data into a 16-byte struct in6_addr on the stack, overflowing by up to 2016 bytes. Note that the main radvd daemon is not affected by the vulnerability. Version 2.21 patches the issue.
