CVE-2016-2107 EXPLOIT
5.9
MEDIUM · CVSS 3.1 · EPSS 89.1% (pctl 100)
Patch early
A public exploit exists.
Description
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.
