Cap'n Proto and its Rust implementation vulnerable to out-of-bounds read due to logic error handling list-of-list

ghsa·2022-12-05

CVE-2022-46149 [MEDIUM] CWE-125 Cap'n Proto and its Rust implementation vulnerable to out-of-bounds read due to logic error handling list-of-list Cap'n Proto and its Rust implementation vulnerable to out-of-bounds read due to logic error handling list-of-list The Cap'n Proto library and capnp Rust package are vulnerable to out-of-bounds read due to logic error handling list-of-list. If a message consumer expects data of type "list of pointers", and if the consumer performs certain specific actions on such data, then a message producer can cause the consumer to read out-of-bounds memory. This could trigger a process crash in the consumer, or in some cases could allow exfiltration of private in-memory data. Impact - Remotely segfault a peer by sending it a malicious message, if the victim performs certain actions on a list-of-pointer type. - Possible exfiltration of memory, if the victim performs additional certain actions on a lis

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.

out-of-bounds read possible when setting list-of-pointers

osv·2022-11-30

CVE-2022-46149 out-of-bounds read possible when setting list-of-pointers out-of-bounds read possible when setting list-of-pointers If a message consumer expects data of type "list of pointers", and if the consumer performs certain specific actions on such data, then a message producer can cause the consumer to read out-of-bounds memory. This could trigger a process crash in the consumer, or in some cases could allow exfiltration of private in-memory data. The C++ Cap'n Proto library is also affected by this bug. See the [advisory](https://github.com/capnproto/capnproto/tree/master/security-advisories/2022-11-30-0-pointer-list-bounds.md) on the main Cap'n Proto repo for a succinct description of the exact circumstances in which the problem can arise.
