OS X 10.5.5 Update Focused on Fixing Bugs


Apple released the OS X 10.5.5 update in the US on Monday afternoon to immediate acclaim as an all-out assault on bugs. Despite initial skepticism, even TUAW, which was first to the tape, acknowledged the release notes are “quite detailed.”

Gizmodo provided a laundry list of items addresed in the update, with MacWorld shortly touting 30 bugs fixed in the new software. Not six hours later, ComputerWorld upped the ante to 70 bugs fixed.

Security experts are finally satisfied the “Dan Kaminski exploit,” referring to the researcher who disclosed a critical flaw in DNS that made it much easier than originally thought to “poison” the cache of DNS servers, or insert bogus information into the Internet’s routing infrastructure, has been fixed.

Apple also updated Mac OS X’s implementation of BIND (Berkeley Internet Name Domain), the open-source DNS software maintained by the Internet Software Consortium (ISC), to keep it current with an early-August version that ISC released to solve performance issues that had shipped in the original fix for Kaminsky’s vulnerability.

The update also fixes a number of non-security flaws, according to the release notes. iCal and Mail both received more than half a dozen fixes, Time Machine got slapped around a bit, and MobileMe even came in for some love.
