Apple this week released a new set of patches to address various security flaws across its product portfolio, including 22 bugs impacting WebKit.
Most of these vulnerabilities, Apple has revealed, could be exploited for the arbitrary execution of code during the processing of maliciously crafted web content. The vulnerabilities are memory corruption issues that have been addressed with improved memory handling.
A total of 19 such flaws were addressed, along with 3 other vulnerabilities that could lead to universal cross site scripting. Also triggered by maliciously crafted web content, these vulnerabilities were addressed with improved state management.

The vulnerability addressed in Telephony could allow the initiator of a phone call “to cause the recipient to answer a simultaneous Walkie-Talkie connection,” Apple explains in an advisory.
