An issue was discovered in certain Apple products. iOS before 10.3.2 is affected. Safari before 10.1.1 is affected. The issue involves the "WebKit" component. It allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted web site.

commandfunction f() { let arr = new Uint32Array(10); for (let i = 0; i < 0x100000; i++) { parseInt(); } arr[8] = 1; arr[-0x12345678] = 2; } f();↗
- →Trigger is a crafted JavaScript function using Uint32Array with a large negative index (-0x12345678) combined with a hot JIT loop (0x100000 iterations), exploiting a signed comparison bug in WebKit JSC's IntegerCheckCombiningPhase::handleBlock during JIT optimization. ↗
- →The vulnerability is triggered via processing maliciously crafted web content in WebKit; network-based delivery via a crafted web site should be monitored for suspicious JavaScript patterns using large negative typed array indices. ↗
- →The root cause is a signed vs. unsigned comparison flaw in IntegerCheckCombiningPhase::handleBlock in WebKit JSC JIT; detection logic should flag JIT-compiled code paths exercising this phase with out-of-bounds negative integer addends. ↗
- ·Vulnerability affects iOS versions before 10.3.2 and Safari versions before 10.1.1; patched in iOS 10.3.2 and Safari 10.1.1. ↗
- ·Debian WebKitGTK packages are resolved/fixed at version 2.16.3-2 across all tracked suites (bookworm, bullseye, forky, sid, trixie). ↗
