EUVDB-ID: #VU44517

Risk: High

CVSSv4.0: 7.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2008-7303

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

The nonet and nointernet sandbox profiles in Apple Mac OS X 10.5.x do not propagate restrictions to all created processes, which allows remote attackers to access network resources via a crafted application, as demonstrated by use of launchctl to trigger the launchd daemon's execution of a script file, a related issue to CVE-2011-1516.

Mitigation

Install update from vendor's website.
