Description

The JavaScript garbage collector in WebKit in Apple Safari before 4.0, iPhone OS 1.0 through 2.2.1, and iPhone OS for iPod touch 1.1 through 2.2.1 does not properly handle allocation failures, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted HTML document that triggers write access to an "offset of a NULL pointer."

Affected products

Apple Safari: through 4.0_beta; through 3.2.3; 0.8, 0.9, 1.0, 1.0.3, 1.1, 1.2 (+18)
