    Summary: Out of bounds write in serde_cbor

    Details: Affected versions of this crate did not properly check if semantic tags were nested excessively during deserialization. This allows an attacker to craft small (< 1 kB) CBOR documents that cause a stack overflow. The flaw was corrected by limiting the allowed number of nested tags.
