CVE-2026-116730
Description
A flaw was found in Furnace. This vulnerability allows an attacker to cause a Denial of Service (DoS) by convincing a user to open a specially crafted FamiTracker module file. The application fails to properly validate instrument note counts during file import, resulting in an out-of-bounds read that crashes the program.
Statement
This vulnerability is rated as Moderate impact because successful exploitation requires explicit user interaction to load a manipulated audio project, leading only to an application crash without compromising system confidentiality or integrity. Furnace is a desktop music tracker not shipped in Red Hat Enterprise Linux, confining potential risk to community desktop environments. The blast radius is limited to a local denial of service affecting the client process during file parsing.
Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Memory
An attacker could get secret values such as cryptographic keys, PII, memory addresses, or other information that could be used in additional attacks.
Confidentiality
Technical Impact: Bypass Protection Mechanism
Out-of-bounds memory could contain memory addresses or other information that can be used to bypass ASLR and other protection mechanisms in order to improve the reliability of exploiting a separate weakness for code execution.
Availability
Technical Impact: DoS: Crash, Exit, or Restart
An attacker could cause a segmentation fault or crash by causing memory to be read outside of the bounds of the buffer. This is especially likely when the code reads a variable amount of data and assumes that a sentinel exists to stop the read operation, such as a NUL in a string.
Other
Technical Impact: Varies by Context
The read operation could produce other undefined or unexpected results.
