A stack-based buffer overflow in dnsproxy in ConnMan before 1.39 could be used by network adjacent attackers to execute code. gdhcp in ConnMan before 1.39 could be used by network-adjacent. attackers to leak sensitive stack information, allowing further exploitation of bugs in gdhcp.

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
