CVE-2022-46149 – Cap'n Proto vulnerable to out-of-bounds read due to logic error handling list-of-list.

https://notcve.org/view.php?id=CVE-2022-46149

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. • https://github.com/capnproto/capnproto/commit/25d34c67863fd960af34fc4f82a7ca3362ee74b9 https://github.com/capnproto/capnproto/security/advisories/GHSA-qqff-4vw4-f6hx https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/EAHKLUMJAXJEV5BPBS5XXWBQ3ZTHGOLY https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PTS6TWD6K2NKXLEEFBPROQXMOFUTEYWY https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WKXM4JAFXLTXU5IQB3OUBQVCIICZWGYX https://lists.fedoraproj • CWE-125: Out-of-bounds Read •
