Technical Description

Two vulnerabilities have been identified in Apple Xcode, which could be exploited by attackers to gain knowledge of sensitive information or compromise a vulnerable system.

The first vulnerability is caused by a buffer overflow error in the Core Image Fun House application when processing malformed ".funhouse" files, which could be exploited by attackers to crash an affected application or execute arbitrary code.

The second issue is caused by an error in WebObjects when generating URLs in HTML documents via the WOHyperlink dynamic element, which could cause WOHyperlink to append a session ID to the generated URL, even for absolute URLs, leading to the disclosure of the current user's session ID to arbnitrary sites.

Affected Products

Apple Xcode tools versions prior to 3.1

Solution

Upgrade to Apple Xcode tools version 3.1.
