TITLE

Apple OS X Audio Vulnerability in Obtaining Important Kernel Memory Layout Information

Trust: 0.8

sources: JVNDB: JVNDB-2016-004074

DESCRIPTION

Audio in Apple OS X before 10.11.6 allows local users to obtain sensitive kernel memory-layout information or cause a denial of service (out-of-bounds read) via unspecified vectors. User interaction is required to exploit this vulnerability in that the target must open a malicious file.The specific flaw exists within the DspFuncLib extension. The issue lies in the failure to properly handle error conditions leading to a dangling pointer being reused after it has been freed. An attacker can leverage this vulnerability to raise privileges and execute code under the context of root. Apple Mac OS X is prone to multiple security vulnerabilities. Attackers can exploit these issues to execute arbitrary code, gain sensitive information, cause denial-of-service conditions, bypass security restrictions, and perform unauthorized actions. This may aid in other attacks. Apple Mac OS X 10.9.5, 10.10.5 and 10.11 through 10.11.5 are vulnerable. Audio is one of the audio components
