Apple on Tuesday released iTunes 9.0.1. Version 9.01 provides a number of fixes, including issues browsing the iTunes Store, a performance issue where iTunes may become unresponsive, the Zoom button not always switching to the mini player. It also improves application syncing for iPod touch and iPhone and adds fixes for unexpected quits, syncing Podcasts in playlists, and sorting albums with multiple discs.
iTunes 9.01 also fixes a cross-platform security on Mac OS X 10.4/105/10.6 systems as well as Windows XP/Vista/7. Apple said that opening a maliciously crafted .pls file may lead to an unexpected application termination or arbitrary code execution due to a buffer overflow that exists in the handling of .pls files: “Opening a maliciously crafted .pls file may lead to an unexpected application termination or arbitrary code execution,” the release documentation stated.
