curl v7.78 contained fixes for five CVEs: CVE-2021-22922[1] and CVE-2021-22923[2] are only present when support for metalink is enabled. EXTRA_OECONF contains "--without-libmetalink" so these fixes are unnecessary. CVE-2021-22926[3] only affects builds for MacOS. CVE-2021-22924[4] and CVE-2021-22925[5] are both applicable. Take the patches from Ubuntu 20.04 curl_7.68.0-1ubuntu2.6 package which is close enough that the patch for CVE-2021-22924 applies without conflicts..

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.
