CVE-2020-8942 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. An arbitrary memory read vulnerability in Asylo versions up to 0.6.0 allows an untrusted attacker to make a call to enc_untrusted_read whose return size was not validated against the requrested size. The parameter size is unchecked allowing the attacker to read memory locations outside of the intended buffer size including memory addresses within the secure enclave. EPSS estimates a 0.13% chance of exploitation in the next 30 days.
