CVE-2017-13804
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 · uneditedAn issue was discovered in certain Apple products. iOS before 11.1 is affected. macOS before 10.13.1 is affected. tvOS before 11.1 is affected. watchOS before 4.1 is affected. The issue involves the "StreamingZip" component. It allows remote attackers to write to unintended pathnames via a crafted ZIP archive.
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 confidenceA path traversal vulnerability in the StreamingZip component allows remote attackers to write files to unintended locations via a specially crafted ZIP archive containing entries with '..' in their pathnames. This enables writing files outside the intended extraction directory.

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.
-
Identify the Apple device and OS typeDetermine whether the device runs iOS, macOS, tvOS, or watchOS. On iOS/tvOS: check Settings > General. On macOS: check Apple menu > About This Mac. On watchOS: check via paired iPhone Watch app.Affected if The device is an Apple product running one of the affected operating systems and processes ZIP archives from untrusted sources
-
Check iOS version on iPhone or iPadGo to Settings > General > About > Version and note the displayed version numberAffected if Version is below 11.1 (for example, 11.0.x or earlier)
-
Check macOS version on MacClick Apple menu > About This Mac and note the version number shown (such as 10.13.0 or earlier)Affected if Version is below 10.13.1
-
Check tvOS version on Apple TVGo to Settings > General > About > Version and note the version numberAffected if Version is below 11.1
-
Check watchOS version on Apple WatchOn paired iPhone, open Watch app > My Watch > General > About and note the watchOS versionAffected if Version is below 4.1
If the device runs iOS < 11.1, macOS < 10.13.1, tvOS < 11.1, or watchOS < 4.1 AND the StreamingZip component processes untrusted ZIP archives, the environment is affected by CVE-2017-13804.

From vendor data4.110.13.111.1
Update to iOS 11.1+, macOS 10.13.1+, tvOS 11.1+, or watchOS 4.1+ as appropriate. If unable to update, avoid opening untrusted ZIP archives from unknown sources.
