OSPF: corrupting the routing database

Synthesis of the vulnerability

An attacker can spoof OSPF messages, in order to corrupt the routing database.
Impacted products: CheckPoint IP Appliance, IPSO, CheckPoint Security Gateway, Cisco ASR, ASA, Cisco Catalyst, IOS by Cisco, IOS XE Cisco, Nexus by Cisco, NX-OS, Cisco Router, ProCurve Switch, HP Switch, Juniper E-Series, Juniper J-Series, JUNOSe, Junos OS, NetScreen Firewall, ScreenOS, SUSE Linux Enterprise Desktop, SLES.

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 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 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.
