Hi,

The following vulnerability was published for rust-capnp.

CVE-2022-46149[0]:
| Cap'n Proto is a data interchange format and remote procedure call
| (RPC) system. Cap'n Proro prior to versions 0.7.1, 0.8.1, 0.9.2, and
| 0.10.3, as well as versions of Cap'n Proto's Rust implementation prior
| to 0.13.7, 0.14.11, and 0.15.2 are vulnerable to out-of-bounds read
| due to logic error handling list-of-list. This issue may lead someone
| to remotely segfault a peer by sending it a malicious message, if the
| victim performs certain actions on a list-of-pointer type.
| Exfiltration of memory is possible if the victim performs additional
| certain actions on a list-of-pointer type. To be vulnerable, an
| application must perform a specific sequence of actions, described in
| the GitHub Security Advisory. The bug is present in inlined code,
| therefore the fix will require rebuilding dependent applications.
| Cap'n Proto has C++ fixes available in versions 0.7.1, 0.8.1, 0.9.2,
| and 0.10.3. The `capnp` Rust crate has fixes available in versions
| 0.13.7, 0.14.11, and 0.15.2.
