JBIG2 decompression in PDF files by the CoreGraphics library.Other significant patches include potential remote code execution holes in: That’s the bug we decribed as “only six characters from a crash.”Īlthough it probably deserved to be called a denial of service rather than merely “an issue,” it was indeed more of an annoyance than a vehicle for cybercrooks.Īt any rate, it’s good to see it patched quickly. OS X Mountain Lion v10.8.5 also addresses an issue where certain Unicode strings could cause applications to unexpectedly terminate. Moving up the list, the not-a-security-fix I mentioned above is included, almost as an afterthought, as follows: Presumably, Apple yielded to public pressure to fix this long-running hole, but, instead of taking all the sudo changes from the past few months, just backported the sudo -k fix to version 1.7.4p6, a much less risky change. Until 10.8.4, doing a sudo -k (which is supposed to deauthenticate you, and thus does not require a password), followed by setting the time to just after midnight on, would give you root access. Nevertheless, the sudo binary has been updated, and in my tests, the privilege escalation bug had vanished. The infamous sudo privilege escalation, documented and patched by sudo itself back in February and pointedly exposed on OS X by Metasploit last month, is no more.Ĭonfusingly, if you run sudo -V to check the version number, you might get the impression it hasn’t been updated, since 1.7.4p6a has the same core version string as the version shipped with 10.8.4 ( 1.7.4p6). I’ll start with the free bonus patch, because I’m delighted it’s happened and I think you should know about it. There are 15 official security patches, one fix that Apple has appended to the list without explicitly admitting that it was a security issue, and one bonus patch that is mentioned on Apple’s website but not in its emailed security advisory. However, those that are not so accustomed to new operating systems might want to hold off on upgrading to Mountain Lion until they are familiar with the new design, which could take several months.I’m calling it a security update, though it’s officially a full-on point release of OS X Mountain Lion, taking the 10.8 variant of Apple’s OS X to version 10.8.5.īut with twice as many security fixes listed as regular bug fixes and improvements, I’m happy to call it a “security update,” if only in the hope you’ll feel a bit more urgency about deploying it. Although users might find the majority of the new features available annoying, they will quickly grow accustomed to the new design and user interface and leave the new features for the time being. This is because the operating system is so stable and efficient. Mac owners and users will have great confidence in finding an OS X Mountain Lion compatible laptop or desktop. For example, with the current version, users can perform background checks on employees, manage multiple email accounts, and install different programs as needed.Īlthough Apple has released several major operating systems, such as Mac OS X Tiger, Mac OS X Mountain Lion, they retain a loyal customer base and a reputation for providing quality products that stand the test of time. Although the upgrade might be the latest in operating systems, it is not considered a revolutionary product, despite introducing some features that are unprecedented. It also features a brand new feature known as LiveArea, which offer users access to their favorite websites, as well as access to their email inboxes. ![]() ![]() The update, version 3.2, provides numerous new features such as support for the latest graphics and video cards, and fixes bugs that may have affected the operating system's security. In addition to this major upgrade, Apple has released an update to the Mac OS X Mountain Lion, which will be available for the first time since the initial launch. Furthermore, this release includes new and exciting new features such as the ability to control access to your Mac from a specific IP address, a built-in Flash reader and improved integration with Corel and Quicktime. Moreover, with OS X Mountain Lion, Apple has enhanced the security of its Mac operating system by introducing stronger protection against malware, including the Gatekeeper application. It also features a completely new way to browse the internet, through the use of a simplified and quick-to-use "Safari" window. For example, it brings a new Safari browser to the Mac OS, which can be used to search the web, browse and locate information on the web. ![]() This new version, however, introduces new features and enhanced capabilities that have been improved over previous versions. OS X Mountain Lion is probably the most anticipated release of Yosemite, Apple's operating system for Mac computers, since the company's earlier release Leopard.
