CVE

GHSA-grg4-wf29-r9vv

Bzip2Decoder doesn't allow setting size restrictions for decompressed data

Impact

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. The malicious input can trigger an OOME and so a DoS attack

Workarounds

No workarounds other than not using the Bzip2Decoder
