Buffer overflows in xtell (xtelld) 1.91.1 and earlier, and 2.x before 2.7, allows remote attackers to execute arbitrary code via (1) a long DNS hostname that is determined using reverse DNS lookups, (2) a long AUTH string, or (3) certain data in the xtell request.
Directory traversal vulnerability in xtell (xtelld) 1.91.1 and earlier, and 2.x before 2.7, allows remote attackers to read files with short names, and local users to read more files using a symlink with a short name, via a .. in the TTY argument.
BIND 8.3.x through 8.3.3 allows remote attackers to cause a denial of service (termination due to assertion failure) via a request for a subdomain that does not exist, with an OPT resource record with a large UDP payload size.
