Apple has rolled no less than 25 patches into the Mac OS X 10.5.4 Leopard update that was announced yesterday. These address a number of Ruby vulnerabilities, as reported here on DaniWeb last month by fellow blogger Davey Winder.
So that's six of the patches accounted for at any rate. Others are a little more difficult to pin down, although Apple does say that they address operating system and application performance issues. It seems, from a quick bit of asking around the usual online suspects, that these include components such as Alias Manager, CoreTypes, c++filt, Net-SMTP, Tomcat, VPN and Webkit as well as the aforementioned Ruby that is.
We also know that the Alias Manager patch deals with a memory corruption issue in OS X 10.4.11 and OS X Server 10.4.11 which manifests itself in the handling of AFP volume mount information in an alias structure.
Then there is the small matter of problems that people have been having with Adobe Creative Suite 3, in particular related to saving and reopening it.
Finally, the Safari problems with loading secure web pages that impacted upon performance are also said to have been fixed.
