TuxGuitar: Arbitrary Code Execution via maliciously crafted `.tg` file

TuxGuitar is an open-source guitar tablature editor. Prior to 2.1.0, an untrusted .tg file can set gervil.soundbank.path to reference an on-disk archive, including the .tg file itself, whose META-INF/services/javax.sound.midi.Soundbank entry names an attacker-supplied class stored in that archive. When a user opens the file, JARSoundbankReader uses an unverified class loader to load and instantiate that class, executing its constructor with the privileges of the TuxGuitar process. This issue is fixed in version 2.1.0.

CVE-2020-14940

An issue was discovered in io/gpx/GPXDocumentReader.java in TuxGuitar 1.5.4. It uses misconfigured XML parsers, leading to XXE while loading GP6 (.gpx) and GP7 (.gp) tablature files.

• Update to 1.5.6+dfsg1-7

CVE-2010-3385

TuxGuitar 1.2 places a zero-length directory name in the LD_LIBRARY_PATH, which allows local users to gain privileges via a Trojan horse shared library in the current working directory.
