Description of the vulnerability

The RFC 2328 defines the OSPF protocol (Open Shortest Path First) which established IP routes, using LSA (Link State Advertisement) messages.

The LSA Type 1 Update (LSU, Link-State Update) message is used to update the routing database. However, the RFC does not request to check the "Link State ID" and "Advertising Router" fields of LSU messages. Several implementations (Cisco, Juniper, etc.) therefore do not perform this check.

An attacker can thus spoof a LSU message if he knows:
 - the IP address of the target router
 - LSA DB sequence numbers
 - the router ID of the OSPF Designated Router

An attacker can therefore spoof OSPF messages, in order to corrupt the routing database.

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 library works on large numbers to perform operations such are RSA.

The BN_bn2dec() function converts a large number to its decimal representation. However, a special number forces BN_div_word() to return a limit value, then data are written after the end of the memory area.

An attacker can therefore generate a memory corruption via BN_bn2dec() of OpenSSL, in order to trigger a denial of service, and possibly to run code.

Description of the vulnerability

The OpenSSL library implements DTLS (Datagram Transport Layer Security, for example on UDP).

In order to manage replays, OpenSSL uses a sliding window containing accepted sequence numbers. However, if an attacker sends a packet with a large sequence number, the window is moved, and legitimate packets thus have numbers before the beginning of the window, and are rejected.

An attacker can therefore send a DTLS packet with a large sequence number to an application compiled with OpenSSL, in order to trigger a denial of service.
