CVE-2015-0285: OpenSSL

Medium severity, CVSS 4.3. EPSS: 5% chance of exploitation in the next 30 days.

The ssl3_client_hello function in s3_clnt.c in OpenSSL 1.0.2 before 1.0.2a does not ensure that the PRNG is seeded before proceeding with a handshake, which makes it easier for remote attackers to defeat cryptographic protection mechanisms by sniffing the network and then conducting a brute-force attack.

Affected products

• OpenSSL OpenSSL: version 1.0.2 only
