VAR-200512-0648

Vulnerability from variot - Updated: 2025-04-03 22:27

Unspecified vulnerability in the Apple Mac OS X kernel before 10.4.2 allows remote attackers to cause a denial of service (kernel panic) via a crafted TCP packet, possibly related to source routing or loose source routing. Apple Mac OS X Tiger Dashboard executes arbitrary widgets with the same "bundle identifier" as a system widget. This can allow a user-installed widget to override a system-installed one. Apple Mac OS X is prone to a remote denial of service vulnerability. The issue exists due to a NULL pointer dereference that manifests in the kernel when specially crafted TCP/IP packets of an unspecified type are processed. A remote attacker may exploit this condition to trigger a kernel panic on a target computer, effectively denying service for legitimate users.

TITLE: Apple Mac OS X Two Vulnerabilities

SECUNIA ADVISORY ID: SA16047

VERIFY ADVISORY: http://secunia.com/advisories/16047/

CRITICAL: Moderately critical

IMPACT: Manipulation of data, DoS

WHERE:

From remote

OPERATING SYSTEM: Apple Macintosh OS X http://secunia.com/product/96/

DESCRIPTION: Two vulnerabilities have been reported in Mac OS X, which can be exploited by malicious people to cause a DoS (Denial of Service) or replace system widgets on a user's system.

2) An error in the Dashboard can be exploited to install widgets with the same internal identifier (CFBundleIdentifier) as an Apple-supplied widgets thereby replacing it.

SOLUTION: Apply patches.
