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.

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.

Description of the vulnerability

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

DTLS packets can be in the wrong order. OpenSSL has to keep them in memory, in order to reassemble them. However, in two cases, message queues are not cleared.

An attacker can therefore send DTLS packets in the wrong order with missing packets to an application compiled with OpenSSL, in order to trigger a denial of service.

Cisco IOS XR: denial of service via fragmented signaling packets

Synthesis of the vulnerability

An authenticated attacker can fragment the signaling flow sent to a Cisco ASR router running IOS XR, in order to trigger a denial of service.
Impacted products: Cisco ASR, IOS XR Cisco.
Severity: 3/4.
Consequences: denial of service on server, denial of service on service.
Provenance: LAN.
Creation date: 11/08/2016.
Identifiers: cisco-sa-20160810-iosxr, CVE-2016-6355, VIGILANCE-VUL-20359.

Description of the vulnerability

The Cisco IOS XS product, when used on an ASR appliance, implements signaling protocols.

These protocols allows some packets to be fragmented. However, the fragmentation management function is subject to a memory leak, which eventually leads to the halt of the signaling protocol management until the appliance reboots.

An authenticated attacker can therefore fragment the signaling flow sent to a Cisco ASR router running IOS XR, in order to trigger a denial of service.

Description of the vulnerability

The OpenSSL product implements the RFC 3161 Public Key Infrastructure Time-Stamp Protocol.

However, the TS_OBJ_print_bio() function tries to read a memory area located outside the expected range, which triggers a fatal error, or leads to the disclosure of a memory fragment.

An attacker can therefore force a read at an invalid address via TS_OBJ_print_bio() of OpenSSL, in order to trigger a denial of service, or to obtain sensitive information.

Impacted products: ASA, Cisco Catalyst, IOS by Cisco, IOS XE Cisco, IOS XR Cisco, Nexus by Cisco, NX-OS, Cisco Router, Juniper E-Series, Juniper J-Series, JUNOSe, Junos OS.
Severity: 2/4.
Consequences: denial of service on server, denial of service on service.
Provenance: LAN.
Creation date: 26/05/2016.
Revisions dates: 27/05/2016, 01/06/2016, 02/06/2016, 06/06/2016, 04/07/2016.
Identifiers: cisco-sa-20160525-ipv6, CSCuz66542, CSCuz79330, CVE-2016-1409, JSA10749, VIGILANCE-VUL-19702.

Description of the vulnerability

The Cisco or Junos product has a service to manage received IPv6 Neighbor Discovery packets.

However, when a malicious packet is received, a fatal error occurs.

An attacker can therefore send a malicious IPv6 Neighbor Discovery packet to Cisco or Junos, in order to trigger a denial of service.

Description of the vulnerability

The source code of OpenSSL includes many loops where a pointer is used to go through a buffer.

The definition of the C language allows a pointer to be off by one byte after the buffer, but the behavior of any further access is undefined. Several end of loop tests follows the forme "pointer + current data length > end pointer" in such a way that these 2 expressions are not always defined according to the language specification. An attacker which can control dynamic memory allocations can trigger evaluation of undefined conditions and perhaps invalid memory access.

An attacker can therefore force a memory access at an invalid address in OpenSSL, in order to trigger a denial of service, or to obtain sensitive information.
