One new jailbreak tweak promises to protect iDevice owners from a recently discovered DoS exploit, which can affect users running apps under both Apple's iOS and OS X. Called GlyphPatch, the free jailbreak tweak provides immunization against the exploit, which targets Safari's WebKit engine and can cause applications to crash unexpectedly when triggered from within SMS messages, iMessages, the Web, and more. Developer Filippo Bigarella explains:
On Aug 29th, 2013, a DoS (Denial of Service) exploit targeting iOS / OS X was disclosed. This exploit is based on a vulnerability affecting iOS / OS X characters rendering engines: this tweak aims to patch that vulnerability in order to protect the user from this kind of attacks, since the exploit can be triggered through different surfaces (SMS, iMessage, web, network SSID).Once downloaded and installed, Bigarella's GlyphPatch can help. The jailbreak tweak comes with no additional settings to configure: just install GlyphPatch, and your iDevice should be protected. GlyphPatch can be downloaded in the Cydia Store free of charge, and is hosted within the BigBoss repository.
