CVE-2015-7073
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 · uneditedApple iOS before 9.2, OS X before 10.11.2, tvOS before 9.1, and watchOS before 2.1 allow remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted SSL handshake.
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 confidenceMemory corruption vulnerability in Apple SSL/TLS implementation during handshake processing. Remote attackers can send specially crafted SSL handshake messages to trigger memory corruption, potentially enabling arbitrary code execution or causing application crashes via heap overflow or similar memory safety violation.

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 iOS version on iPhone or iPadGo to Settings > General > About and look at the Version field, or connect the device to a computer with iTunes and check the device summary pageAffected if Version displays 9.1 or lower (for example, 9.0, 8.x, etc.)
-
Check macOS versionOpen Terminal and run: sw_vers -productVersionAffected if Version displays 10.11.1 or lower (for example, 10.11.0, 10.10.x, etc.)
-
Check tvOS version on Apple TVGo to Settings > General > About > Version on the Apple TV deviceAffected if Version displays 9.0 or lower
-
Check watchOS version on Apple WatchOpen the Watch app on paired iPhone, go to My Watch > General > About, and check the Version fieldAffected if Version displays 2.0 or lower (for example, 1.x)
-
Verify SSL/TLS is enabledConfirm that any network client or server application using Secure Transport (or similar Apple SSL/TLS stack) is in use; this is enabled by default on these platforms for HTTPS and other TLS connectionsAffected if The device uses any SSL/TLS connections (Safari, mail, third-party apps, or custom network services)
If the device runs any affected OS version at or below the thresholds AND uses SSL/TLS connections, it is vulnerable to the SSL handshake memory corruption flaw.

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 dataApply vendor security updates: upgrade iOS to 9.2+, OS X to 10.11.2+, tvOS to 9.1+, and watchOS to 2.1+ to patch the SSL handshake memory corruption flaw.
