WebKit, as used in Apple iOS before 8.1.1 and Apple TV before 7.0.2, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted web site, a different vulnerability than CVE-2014-4462.
Use-after-free vulnerability in the ProcessingInstruction::setXSLStyleSheet function in core/dom/ProcessingInstruction.cpp in the DOM implementation in Blink, as used in Google Chrome before 38.0.2125.101, allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors.
Apple iTunes before 8.0 on Mac OS X 10.4.11, when iTunes Music Sharing is enabled but blocked by the host-based firewall, presents misleading information about firewall security, which might allow remote attackers to leverage an exposure that would be absent if the administrator were given better information.
