libevent: Libevent: Off-by-one stack buffer overflow leading to denial of service or data corruption

A flaw was found in Libevent, an event notification library. An off-by-one stack buffer overflow exists in the dnsnametolabels function when processing a name-bearing DNS record. A remote attacker could send a specially crafted DNS server response, which may lead to a crash or corruption of the...
