In Expat (aka libexpat) before 2.4.5, an attacker can trigger stack exhaustion in build_model via a large nesting depth in the DTD element. Backport patch from: https://github.com/libexpat/libexpat/pull/558/commits/9b4ce651b26557f16103c3a366c91934ecd439ab Also add patch which fixes a regression introduced in the above fix: https://github.com/libexpat/libexpat/pull/566 CVE: CVE-2022-25313 (From OE-Core rev: 8105700b1d6d23c87332f453bdc7379999bb4b03) Signed-off-by: Steve Sakoman <steve@sakoman.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
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.
