GHSA-25M7-RWWF-46F2
Vulnerability from github – Published: 2024-04-02 21:30 – Updated: 2024-04-02 21:30Foxit PDF Reader Annotation Out-Of-Bounds Read Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Foxit PDF Reader. 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 handling of Annotation objects. The issue results from the lack of proper validation of user-supplied data, which can result in 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-22707.

Vulnerability from github – Published: 2026-05-06 12:30 – Updated: 2026-08-09 21:30In the Linux kernel, the following vulnerability has been resolved:
netconsole: avoid OOB reads, msg is not nul-terminated
msg passed to netconsole from the console subsystem is not guaranteed to be nul-terminated. Before recent commit 7eab73b18630 ("netconsole: convert to NBCON console infrastructure") the message would be placed in printk_shared_pbufs, a static global buffer, so KASAN had harder time catching OOB accesses. Now we see:

GHSA-25MX-8F3V-8WH7
Vulnerability from github – Published: 2023-06-06 01:58 – Updated: 2025-07-28 15:56Affected versions of the crate have several bugs where attacker-controlled input can result in the use of an out-of-bound array index. Rust detects the use of the out-of-bound index and causes the application to panic. An attacker may be able to use this to cause a denial-of-service. However, it is not possible for an attacker to read from or write to the application's address space.

If the input of the decode-mpls.c function DecodeMPLS is composed only of a packet of source address and destination address plus the correct type field and the right number for shim, an attacker can manipulate the control flow, such that the condition to leave the loop is true. After leaving the loop, the network packet has a length of 2 bytes. There is no validation of this length. Later on, the code tries to read at an empty position, leading to a crash.

GHSA-25X6-6C2H-M4MM
Vulnerability from github – Published: 2022-05-24 17:30 – Updated: 2022-05-24 17:30An exploitable information disclosure vulnerability exists in the dev_read functionality of F2fs-Tools F2fs.Fsck 1.13. A specially crafted f2fs filesystem can cause an uninitialized read resulting in an information disclosure. An attacker can provide a malicious file to trigger this vulnerability.

Mitigation MIT-5
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
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.
