CVE-2016-7742


TITLE

Apple macOS of xar Vulnerability in arbitrary code execution in components

Trust: 0.8

sources: JVNDB: JVNDB-2016-007416

DESCRIPTION

An issue was discovered in certain Apple products. macOS before 10.12.2 is affected. The issue involves the "xar" component, which allows remote attackers to execute arbitrary code via a crafted archive that triggers use of uninitialized memory locations. Apple macOS is prone to an arbitrary code-execution vulnerability. Failed exploit attempts will result in a denial-of-service condition. Versions prior to macOS 10.12.2 are vulnerable. Apple macOS Sierra is a dedicated operating system developed by Apple for Mac computers. xar is one of those tools that provides an easily extensible archive format
