Packages
| Ecosystem | Package | Affected | Fixed in |
|---|---|---|---|
| Go | go.etcd.io/etcd | < 0.5.0-alpha.5.0.20200423152442-f4b650b51dc4 | 0.5.0-alpha.5.0.20200423152442-f4b650b51dc4 |
Details
As written in the advisory (Markdown source, shown as plain text).
### Vulnerability type
Data Validation
### Detail
The size of a record is stored in the length field of a WAL file and no additional validation is done on this data. Therefore, it is possible to forge an extremely large frame size that can unintentionally panic at the expense of any RAFT participant trying to decode the WAL.
### Specific Go Packages Affected
github.com/etcd-io/etcd/wal
