AV:L/AC:L/Au:N/C:N/I:P/A:N

Name of the Vulnerable Software and Affected Versions libSystem library in Apple Mac OS X versions 10.3.9 through 10.4.2

Description The issue allows local users to overwrite arbitrary files by setting the MallocLogFile environment variable to the target file before running a setuid application. This is due to a problem in the malloc function within the libSystem library.

Recommendations For Mac OS X versions 10.3.9 through 10.4.2, consider restricting the use of setuid applications or avoid setting the MallocLogFile environment variable to sensitive files until a fix is available. As a temporary workaround, restrict access to sensitive files that could be overwritten by exploiting this issue.
