CVE-2017-9607 (CCN-132392)

Assigned:2017-06-13
Published:2017-06-13
Updated:2017-10-03
Summary:The BL1 FWU SMC handling code in ARM Trusted Firmware before 1.4 might allow attackers to write arbitrary data to secure memory, bypass the bl1_plat_mem_check protection mechanism, cause a denial of service, or possibly have unspecified other impact via a crafted AArch32 image, which triggers an integer overflow.
