Details
This vulnerability allows remote attackers to disclose sensitive information on affected installations of Bentley MicroStation CONNECT 10.16.02.034. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of 3DS files. Crafted data in a 3DS file can trigger a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process. Was ZDI-CAN-16342.

FRRouting before 10.5.3 contains an integer overflow vulnerability in seven OSPF Traffic Engineering and Segment Routing TLV parser functions where a uint16_t accumulator variable truncates uint32_t values returned by the TLV_SIZE() macro, causing the loop termination condition to fail while pointer advancement continues unchecked. Attackers with an established OSPF adjacency can send a crafted LS Update packet with a malicious Type 10 or Type 11 Opaque LSA to trigger out-of-bounds memory reads and crash all affected routers in the OSPF area or autonomous system.

Details
MAX PRESENCE V100R001C00, TP3106 V100R002C00, TP3206 V100R002C00 have an out-of-bounds read vulnerability in H323 protocol. An attacker logs in to the system as a user and send crafted packets to the affected products. Due to insufficient verification of the packets, successful exploit will cause process reboot.
Severity

Mitigation MIT-5
Implementation
Strategy: Input Validation
- Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
- When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
- Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
- To reduce the likelihood of introducing an out-of-bounds read, ensure that you validate and ensure correct calculations for any length argument, buffer size calculation, or offset. Be especially careful of relying on a sentinel (i.e. special character such as NUL) in untrusted inputs.
Mitigation
Architecture and Design
Strategy: Language Selection
Use a language that provides appropriate memory abstractions.
CAPEC-540: Overread Buffers
An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.
