Description Vincent Danen 2011-10-05 17:56:16 EDT

A number of buffer overread flaws were found in radvd's process_ra() function due to numerous missed len() checks. This can lead to memory reads outside of the stack, resulting in a crash of radvd. (CVE-2011-3604)

This is corrected in upstream git [1].
