CVE-2022-31009Network attack vector

Repeated crashes via invalid accent color assertion

Published Jun 23, 2022 · Updated Apr 23, 2025

Reachable assertion in Wire Swiss GmbH Wire iOS before 3.100 allows remote authenticated users to trigger repeated crashes via crafted accent colors. The nameColor(for:variant:) helper asserts that a received ZMAccentColor raw value is within range instead of converting it with a safe default. An authenticated Wire user can send the invalid color to a communication partner, and the recipient's interaction with the affected client can leave it partially unusable across repeated launches.
