Fix 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. 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.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
