Apple has issued updates for iPhoto, ProKit, and Braille Display. iPhoto 7.1.2 addresses issues when publishing photos to a .Mac Web Gallery, improves overall stability, and fixes several other minor issues, according to Apple. The issue could arise when users subscribe to a maliciously crafted photocast, which may lead to arbitrary code execution.

ProKit 4.5 improves reliability for Apple’s professional applications, according to the company, and is recommended for all users of Final Cut Studio, Final Cut Express, Aperture, Logic Studio, and Logic Express.

Apple’s Braille Display Update 1.0 adds support to Apple’s screen reading software, called VoiceOver, in Mac OS X 10.5.
