  "description": "Cap\u0027n Proto is a data interchange format and remote procedure call (RPC) system. Cap\u0027n Proro prior to versions 0.7.1, 0.8.1, 0.9.2, and 0.10.3, as well as versions of Cap\u0027n Proto\u0027s 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\u0027n Proto has C\u002B\u002B fixes available in versions 0.7.1, 0.8.1, 0.9.2, and 0.10.3. The \u0060capnp\u0060 Rust crate has fixes available in versions 0.13.7, 0.14.11, and 0.15.2.",
