CVE-2015-1088
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 · uneditedCFURL in Apple iOS before 8.3 and Apple OS X before 10.10.3 does not properly validate URLs, which allows remote attackers to execute arbitrary code via a crafted web site.
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 confidenceCFURL (Core Foundation URL handling) in Apple iOS before 8.3 and OS X before 10.10.3 fails to properly validate URLs, allowing attackers to craft malicious URLs that bypass security checks and execute arbitrary code when a user visits a compromised website.

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 > Version and note the displayed version numberAffected if Version is 8.2 or lower (for example, 8.2, 8.1, 8.0, or earlier)
-
Check OS X version on MacClick the Apple menu > About This Mac and note the OS X version displayed (such as 10.10.2, 10.10.1, 10.10.0)Affected if Version is 10.10.2 or lower (for example, 10.10.2, 10.10.1, 10.10.0)
-
Confirm Core Foundation URL handling is in useThe CFURL component is a core system library included with iOS and OS X; any application that processes URLs on the device relies on this componentAffected if The affected OS version is detected, meaning the CFURL component shipped with that version contains the vulnerability
A user is affected if their device runs iOS 8.2 or earlier, or OS X 10.10.2 or earlier, because these versions contain the vulnerable CFURL component that fails to properly validate URLs.

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 affected devices to iOS 8.3+ or OS X 10.10.3+ to obtain the patched CFURL component. Until patched, restrict user access to untrusted websites.
