The version of Apple Safari installed on the remote macOS or Mac OS X host is prior to 10.0.2. It is, therefore, affected by multiple vulnerabilities :

  • Multiple remote code execution vulnerabilities exist in WebKit due to improper validation of user-supplied input and improper handling of objects in memory. An unauthenticated, remote attacker can exploit these vulnerabilities, by convincing a user to visit a specially crafted website, to corrupt memory and execute arbitrary code. (CVE-2016-4692, CVE-2016-7635, CVE-2016-7652)

  • Multiple information disclosure vulnerabilities exist in WebKit due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit these, by convincing a user to visit a specially crafted website, to disclose memory contents. (CVE-2016-4743, CVE-2016-7656)

  • An information disclosure vulnerability exists in WebKit due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this, by convincing a user to visit a specially crafted website, to disclose user information. (CVE-2016-7586)

  • Multiple remote code execution vulnerabilities exist in WebKit due to improper validation of user-supplied input and improper state management. An unauthenticated, remote attacker can exploit these vulnerabilities, by convincing a user to visit a specially crafted website, to corrupt memory and execute arbitrary code.
    (CVE-2016-7587, CVE-2016-7589:, CVE-2016-7610, CVE-2016-7611, CVE-2016-7639, CVE-2016-7640, CVE-2016-7641, CVE-2016-7642, CVE-2016-7645, CVE-2016-7646, CVE-2016-7648, CVE-2016-7649, CVE-2016-7654)

  • An information disclosure vulnerability exists in WebKit due to improper handling of JavaScript prompts. An unauthenticated, remote attacker can exploit this, by convincing a user to visit a specially crafted website, to corrupt memory and execute arbitrary code.
    (CVE-2016-7592)

  • An information disclosure vulnerability exists in WebKit due to the use of uninitialized memory. An unauthenticated, remote attacker can exploit this, by convincing a user to visit a specially crafted website, to disclose memory contents. (CVE-2016-7598)

  • An information disclosure vulnerability exists that is triggered when handling HTTP redirections. An unauthenticated, remote attacker can exploit this, by convincing a user to visit a specially crafted website, to disclose user information. (CVE-2016-7599)

  • An information disclosure vulnerability exists in WebKit due to improper validation of user-supplied input and blob URLs. An unauthenticated, remote attacker can exploit this, via a specially crafted blob URL, to disclose user information. (CVE-2016-7623)

  • A remote code execution vulnerability exists in WebKit due to improper validation of user-supplied input and improper state management. An unauthenticated, remote attacker can exploit this, by convincing a user to visit a specially crafted website, to cause a denial of service condition or the execution of arbitrary code.
    (CVE-2016-7632)

  • A cross-site scripting (XSS) vulnerability exists in Safari Reader due to improper validation of user-supplied input. An unauthenticated, remote attacker can exploit this, by convincing a user to follow a specially crafted link, to execute arbitrary script code in a user’s browser session. (CVE-2016-7650)
