CVE-2015-3794

TITLE

Apple OS X of Speech UI Vulnerable to arbitrary code execution

Trust: 0.8

sources: JVNDB: JVNDB-2015-004285

DESCRIPTION

The Speech UI in Apple OS X before 10.10.5, when speech alerts are enabled, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted Unicode string. Apple Mac OS X is prone to multiple security vulnerabilities. Attackers can exploit these issues to execute arbitrary code with system privileges, gain admin privileges, bypass security restrictions, cause denial-of-service conditions, obtain sensitive information, and perform other attacks. Note: The issue described by CVE-2015-3778 has been removed. The issue is discussed in BID 83590 (Apple Mac OS X and iOS CVE-2015-3778 Information Disclosure Vulnerability). These issues affect OS X prior to 10.10.5. Speech UI is one of the speech user interface components
