Apple on Wednesday released Security Update 2006-001, available for download through Software Update system preference pane and from Apple’s
Web page. The update addresses a recently reported exploit that left Safari users vulnerable to malicious shell scripts; corrects a vulnerability to Apple’s Mail software and also changes the way iChat handles file transfers to help prevent the “Leap-A” malware.
“Apple today posted Mac OS X security update 2006-001 that fixes both the recently reported Leap-A and Safari security vulnerabilities,” an Apple spokesman told
. “This update is available automatically to all users through Apple’s free Software Update service or at
http://www.apple.com/support/downloads. To maintain maximum system security, Apple always advises that all Mac OS X users keep their system current by installing this and all Mac OS X software updates.”
Separate downloads have been made available from Apple’s Web site for Mac OS X v10.3.9 “Panther” client and server versions, as well as Mac OS X v10.4.5 “Tiger” Intel and PowerPC versions.
Apple recommends the updates for all users.
