What is CVE-2016-8860?

In previous versions of Tor, certain internal functions assumed that data buffers were properly NUL terminated. This oversight allowed remote attackers to craft data that could exploit this flaw, leading to a denial of service. Such an attack could result in crashes affecting clients, hidden services, relays, or the authority, thus compromising the stability and security of the Tor network.
