CVE-2000-1219
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 · uneditedThe -ftrapv compiler option in gcc and g++ 3.3.3 and earlier does not handle all types of integer overflows, which may leave applications vulnerable to vulnerabilities related to overflows.
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 confidenceThe -ftrapv compiler option in gcc/g++ 3.3.3 and earlier was intended to trap integer overflows at runtime, but it does not handle all types of integer overflows. Applications compiled with this option may still be vulnerable to integer overflow-related security issues, as the compiler fails to catch all overflow conditions that could lead to exploitable behavior.

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.
-
Check installed GCC versionRun `gcc --version` to determine the GCC compiler version installed on the systemAffected if The version displayed is 3.3.3 or earlier
-
Check installed G++ versionRun `g++ --version` to determine the G++ compiler version installed on the systemAffected if The version displayed is 3.3.3 or earlier
-
Identify binaries compiled with -ftrapvSearch compiled binaries or object files for the -ftrapv flag by examining build logs, Makefiles, or using `strings` on binaries to look for related compiler instrumentationAffected if Binaries were compiled using -ftrapv with GCC/G++ 3.3.3 or earlier
-
Audit source code for -ftrapv usageReview build configuration files (Makefiles, CMakeLists.txt, build scripts) for instances of the -ftrapv compiler flagAffected if The flag -ftrapv appears in CXXFLAGS or CFLAGS for any compilation unit
You are affected if you have GCC or G++ version 3.3.3 or earlier and compile code with the -ftrapv option, as the compiler will fail to trap all integer overflow conditions that could lead to security issues.

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 dataUpgrade to a newer gcc/g++ version beyond 3.3.3 where -ftrapv has improved coverage, or implement explicit manual integer overflow checks in the code rather than relying solely on compiler-generated overflow traps.
