Format string vulnerability in PackageKit in Apple Mac OS X 10.6.x before 10.6.6 allows man-in-the-middle attackers to execute arbitrary code or cause a denial of service (application crash) via vectors related to interaction between Software Update and distribution scripts.

Weakness

The product uses a function that accepts a format string as an argument, but the format string originates from an external source.

Extended Description

When an attacker can modify an externally-controlled format string, this can lead to buffer overflows, denial of service, or data representation problems. It should be noted that in some circumstances, such as internationalization, the set of format strings is externally controlled by design. If the source of these format strings is trusted (e.g. only contained in library files that are only modifiable by the system administrator), then the external control might not itself pose a vulnerability.
