Summary

The Bzip2 decompression decoder function doesn't allow setting size restrictions on the decompressed output data (which affects the allocation size used during decompression). All users of Bzip2Decoder are affected.

Risk Assessment

Malicious input can trigger an OutOfMemoryError and lead to a denial of service (DoS) attack.

Recommendation

Upgrade the library containing Bzip2Decoder to a version with size restrictions, or enforce decompressed data size limits at the application level.
