Directory traversal vulnerability in the WML engine preprocessor for Wesnoth 1.2.x before 1.2.8, and 1.3.x before 1.3.12, allows remote attackers to read arbitrary files via ".." sequences in unknown vectors.

Unspecified vulnerability in Wesnoth 1.2.x before 1.2.8, and 1.3.x before 1.3.12, allows attackers to cause a denial of service (hang) via a "faulty add-on" and possibly execute other commands via unknown vectors related to the turncmd option.

The readgamemap function in src/terraintranslation.cpp in Wesnoth before r32987 allows remote attackers to cause a denial of service (memory consumption and daemon hang) via a map with a large (1) width or (2) height.

The uncompressbuffer function in src/server/simplewml.cpp in Wesnoth before r33069 allows remote attackers to cause a denial of service via a large compressed WML document.
