Description of the vulnerability

The OpenSSL product implements the SSL version 3 protocol.

The SSL3_AL_WARNING message is used to send an alert of level Warning. However, when these packets are received during the handshake, the library consumes 100% of CPU.

An attacker can therefore send SSL3_AL_WARNING packets to an SSLv3 application linked to OpenSSL, in order to trigger a denial of service.

Description of the vulnerability

The OpenSSL version 1.0.2i product fixed a bug in CRL management.

However, this fix does not check if a pointer is NULL, before using it.

An attacker can therefore force a NULL pointer to be dereferenced via a CRL on an application linked to OpenSSL 1.0.2i, in order to trigger a denial of service.

Description of the vulnerability

The Blowfish and Triple-DES symetric encryption algorithms use 64 bit blocks.

However, if they are used in CBC mode, a collision occurs after 785 GB transferred, and it is then possible to decrypt blocks with an attack lasting two days.

An attacker can therefore create a TLS/VPN session with a Blowfish/Triple-DES algorithm, and perform a two days attack, in order to decrypt data.
