CVE-2017-5208
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 · uneditedInteger overflow in the wrestool program in icoutils before 0.31.1 allows remote attackers to cause a denial of service (memory corruption) via a crafted executable, which triggers a denial of service (application crash) or the possibility of execution of arbitrary code.
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 · high confidenceInteger overflow in the wrestool program of icoutils (versions before 0.31.1) allows processing of crafted executables to cause memory corruption, leading to denial of service (application crash) or potentially arbitrary code execution.

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.
-
Verify icoutils package is installedOn Debian-based systems: dpkg -l | grep icoutils. On RHEL-based systems: rpm -qa | grep icoutilsAffected if The package is installed and its version is below 0.31.1
-
Determine wrestool versionRun 'wrestool --version' or 'wrestool -V' to obtain the exact version number of the wrestool binaryAffected if The reported version is less than 0.31.1 (for icoutils source) or the package version is older than the version shipped in RHEL 7.3+/Debian 8 updates
-
Check if wrestool processes untrusted executablesReview any scripts, automation, or workflows that invoke wrestool on input files from untrusted sources (e.g., downloaded PE executables, third-party binaries)Affected if wrestool is used to process executable files from untrusted or external sources without verification
-
Confirm vulnerability trigger conditionThe flaw is triggered when wrestool parses a crafted Win32 executable (PE format). No specific config toggle exists; the bug is in the parsing logic itself.Affected if Any use of wrestool on potentially malicious or unvalidated PE executables could trigger the integer overflow
You are affected if icoutils/wrestool is installed with a version below 0.31.1 and you use it to process executable files from untrusted sources.
Generated from the published advisory. Verify against your own configuration.
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 data0.31.1
Upgrade icoutils to version 0.31.1 or later to patch the integer overflow vulnerability. Verify no other affected versions remain in the environment.
