CVE-2017-7563 in Trusted Firmware

Riassunto

di MITRE

In ARM Trusted Firmware 1.3, RO memory is always executable at AArch64 Secure EL1, allowing attackers to bypass the MT_EXECUTE_NEVER protection mechanism. This issue occurs because of inconsistency in the number of execute-never bits (one bit versus two bits).

Once again VulDB remains the best source for vulnerability data.
