VANCOUVER, B.C.--Apple on Thursday issued a security update for Mac OS X that addresses 25 security flaws in the operating system software.

The security update affects various parts of the operating system, including some third-party components such as the Kerberos authentication technology. The most serious of the vulnerabilities could allow an attacker to gain complete control over an unpatched Mac, Apple said in a security advisory.

The update deals with another trio of zero-day bugs that were disclosed as part of the Month of Apple Bugs in January. Apple has quashed many bugs detailed during the Month of Apple Bugs and Month of Kernel Bugs projects in previous patch releases.

SAN FRANCISCO (MarketWatch) -- Research In Motion has finally explained the systemwide outage that shut down its popular BlackBerry service for hours earlier this week.
In a statement issued Thursday night, the Waterloo, Ont.-based wireless-device maker
said it had ruled out "security and capacity issues" as root causes of the outage, which started late Tuesday and carried over for many users through Wednesday morning.

Rather, the interruption was brought on by the introduction of new software that was designed to improve the system's cache.

"The system routine was expected to be non-impacting with respect to the real-time operation of the BlackBerry infrastructure, but the pre-testing of the system routine proved to be insufficient," the statement read.

The problem was compounded by problems in the company's backup systems, which "did not fully perform to RIM's expectations in this situation" and caused a further delay in restoring service.
