Last modified

CVE-2016-2107 is a medium-severity vulnerability rated 5.9/10 on the CVSS scale. The AES-NI implementation in OpenSSL before 1.0.1t and 1.0.2 before 1.0.2h does not consider memory allocation during a certain padding check, which allows remote attackers to obtain sensitive cleartext information via a padding-oracle attack against an AES CBC session. NOTE: this vulnerability exists because of an incorrect fix for CVE-2013-0169.. EPSS estimates a 89.06% chance of exploitation in the next 30 days.
