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 · unedited
Integer overflow in Arora allows remote attackers to bypass intended port restrictions on outbound TCP connections via a port number outside the range of the unsigned short data type, as demonstrated by a value of 65561 for TCP port 25.

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 confidence

Integer overflow in Arora browser's port validation allows attackers to bypass intended port restrictions. When a port number exceeding 65535 is provided, it overflows the unsigned short data type (e.g., 65561 wraps to 25), enabling connections to normally restricted ports like SMTP.

MitigationArora is largely unmaintained; upgrade to a supported browser with current security patches. If patching is required, implement proper bounds checking to validate port numbers are within 0-65535 before use.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Verify Arora browser installation
    Check for Arora browser on the system. On Windows, look in Program Files for 'arora' folder or check Start Menu. On Linux, run 'which arora' or check /usr/bin/arora. On macOS, check /Applications for Arora.app.
    Affected if Arora browser is found installed on the system
  2. Identify Arora version
    Launch Arora and navigate to Help > About, or check the executable version properties. Compare against the affected range (all versions are affected per CVE-2010-1100).
    Affected if Any version of Arora browser is installed (all versions are affected)
  3. Confirm browser network capability
    Attempt to load any website in Arora to verify the browser can make outbound network connections.
    Affected if Arora can establish network connections, enabling the port validation overflow to be exploited

If Arora browser is installed and functional, the environment is affected because all versions contain the integer overflow flaw in port validation that allows restricted port access.
