CVE-2026-24800
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedOut-of-bounds Write, Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') vulnerability in tildearrow furnace (extern/zlib modules). This vulnerability is associated with program files inflate.C.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA classic buffer overflow vulnerability exists in the zlib inflate module (inflate.C) of tildearrow furnace. The vulnerability stems from insufficient bounds checking during buffer copy operations, allowing an attacker to write data beyond allocated buffer boundaries. This out-of-bounds write could enable arbitrary code execution or denial of service.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify tildearrow furnace installation and versionCheck for the presence of the tildearrow furnace executable or library (commonly named 'furnace' or similar) and retrieve its version using --version flag or checking application metadataAffected if The installed version is older than the patched version (once released) or cannot be determined to be patched
-
Locate the zlib inflate module in the installationSearch the application directory for inflate.C or compiled inflate object files (inflate.o, inflate.obj) or the compiled zlib library (libz.a, zlib.dll, etc.)Affected if The vulnerable inflate.C source file or its compiled derivatives are present in the installation
-
Determine if the software processes external untrusted inputReview application logs, configuration files, or runtime behavior to confirm whether tildearrow furnace loads or processes audio files, presets, or other data from untrusted or network sourcesAffected if The application is configured to accept or process input from untrusted sources (network, user-uploaded files, or external presets) that would invoke the zlib inflate functions
-
Inspect for crash logs or memory corruption indicatorsExamine system event logs, application crash dumps, or stderr/stdout output for signs of memory corruption, buffer overflow errors, or unexpected crashes during file loadingAffected if Crashes or memory corruption errors occur when loading compressed audio files, presets, or other data that triggers the inflate functionality
A user is affected if tildearrow furnace is installed with an unpatched version and processes untrusted or external input that triggers the vulnerable zlib inflate buffer copy operations.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate to the latest version of tildearrow furnace once a patch is released. If immediate patching is not possible, consider network-level restrictions on input sources and input validation before passing data to the affected zlib inflate functions.
