Apple on Tuesday issued a security update for its Mac OS X to plug 45
security holes, including several zero-day vulnerabilities.
The megapatch is the seventh Apple security patch release in three months.
It deals with vulnerabilities in Apple's own software, as well as
third-party components such as Adobe Systems' Flash Player, OpenSSH and
MySQL. Sixteen of the vulnerabilities addressed by the update were
previously released as part of two high-profile bug-hunting campaigns.
The vulnerabilities pose varying risks to Macs. Several of the flaws could
be exploited to gain full control over a Mac running the vulnerable
component, according to Apple's advisory. Other holes are limited and
could only be exploited to crash a Mac or used by somebody who already has
access to a machine to elevate privileges, for example.
One focus of the patch is to fix eight vulnerabilities in the way Mac OS X
handles disk images, files that when opened appear as a drive within the
Macintosh Finder. Mounting a malicious image may lead to an error and
could provide a means for an attacker to breach a Mac, Apple said.
Tuesday's update deals with nine vulnerabilities released as part of the
Month of Apple Bugs in January and seven bugs disclosed in the Month of
Kernel Bugs in November. In earlier fix releases, Apple fixed several
flaws identified during the projects.
While several of the vulnerabilities repaired by Apple's updates were
previously known, it doesn't appear that any attacks that exploited the
flaws actually occurred.
In addition to the Mac OS X patch, Apple issued a second update on Tuesday
to fix a security bug in iPhoto that could expose Mac users to a serious
attack. An attacker could craft a malicious "photocast" which, when
opened, could compromise a Mac, Apple said in its alert. The Photocasts
feature allows people to share pictures in iPhoto.
Tuesday's two releases bring Apple's total patch count for the year to
seven. Microsoft, meanwhile, on Tuesday skipped its monthly patch day.
However, it released a dozen security bulletins with fixes for 20
vulnerabilities in February and four bulletins with fixes for 10 bugs in
The Apple patch can be downloaded and installed via the Software Update
feature in Mac OS X, or from Apple Downloads.
