CVE-2021-31810: A malicious FTP server can use the PASV response to trick Net::FTP into connecting back to a given IP address and port. This potentially makes Net::FTP extract information about services that are otherwise private and not disclosed (e.g., the attacker can conduct port scans and service banner extractions). CVE-2021-32066: Net::IMAP does not raise an exception when StartTLS fails with an unknown response, which might allow man-in-the-middle attackers to bypass the TLS protections by leveraging a network position between the client and the registry to block the StartTLS command, aka a “StartTLS stripping attack.” References: https://www.ruby-lang.org/en/news/2021/07/07/trusting-pasv-responses-in-net-ftp/ https://www.ruby-lang.org/en/news/2021/07/07/starttls-stripping-in-net-imap/ Patches from:bf4d05173ce2ac25d0eb(From OE-Core rev: e14761916290c01683d72eb8e3de530f944fdfab) Signed-off-by: Yi Zhao <yi.zhao@windriver.com> Signed-off-by: Anuj Mittal <anuj.mittal@intel.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.
