CVE-2016-2177: Integer Overflow

First published: Thu May 05 2016(Updated: )

A common idiom in the codebase is: if (p + len > limit) { return; /* Too long */ } where p points to some malloc'd data of SIZE bytes and limit == p + SIZE. 'len' could be from some externally supplied data, e.g. TLS message. This idiom is vulnerable to integer overflow vulnerability.
