    (CVE-2017-2513)

  - Multiple buffer overflow conditions exist in the SQLite     component due to the improper validation of     user-supplied input. An unauthenticated, remote attacker     can exploit these, via a specially crafted SQL query, to     execute arbitrary code. (CVE-2017-2518, CVE-2017-2520)

  - A memory corruption issue exists in the SQLite component     when handling SQL queries. An unauthenticated, remote     attacker can exploit this, via a specially crafted SQL     query, to execute arbitrary code. (CVE-2017-2519)

  - An unspecified memory corruption issue exists in the     TextInput component when parsing specially crafted data.
    An unauthenticated, remote attacker can exploit this to     execute arbitrary code. (CVE-2017-2524)

  - Multiple memory corruption issues exist in SQLite 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 execute arbitrary code.
    (CVE-2017-6983, CVE-2017-6991)

  - An unspecified flaw exists in the AVEVideoEncoder     component that allows a local attacker, via a specially     crafted application, to corrupt memory and execute     arbitrary code with kernel-level privileges.
    (CVE-2017-6989)

  - Multiple type confusion flaws exist in SQLite due to     improper validation of user-supplied input to 'snippet',     'offsets', and 'matchinfo'. An unauthenticated, remote     attacker can exploit these, by convincing a user to     visit a specially crafted website, to execute arbitrary     code. (CVE-2017-7000, CVE-2017-7001, CVE-2017-7002)

  - A denial of service vulnerability exists in the     CoreText component due to improper validation of     user-supplied input. An unauthenticated, remote attacker     can exploit this, via a specially crafted file, to crash     an application. (CVE-2017-7003)

This update was imported from the SUSE:SLE-12-SP2:Update update project.

The version of iOS running on the mobile device is prior to 10.3.2, and is affected by multiple vulnerabilities :

 - A use-after-free error exists in the handling of RenderElement objects. With a specially crafted web page, a context-dependent attacker can dereference already freed memory and potentially execute arbitrary code.
 - A use-after-free error exists in the handling of RenderLayer objects. With a specially crafted web page, a context-dependent attacker can dereference already freed memory and potentially execute arbitrary code.
 - A use-after-free error exists in the handling of RenderInline objects. With a specially crafted web page, a context-dependent attacker can dereference already freed memory and potentially execute arbitrary code.
 - A flaw exists that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and potentially execute arbitrary code.
 - An unspecified flaw exists related to the certificate trust policy that is triggered when handling trust acceptance. This may allow a context-dependent attacker to potentially cause untrusted certificates to be treated as trusted.
 - An unspecified flaw exists in the Safari history menu. With a specially crafted web page, a context-dependent attacker can cause an application denial of service.
 - A logic flaw exists that allows a universal cross-site scripting (UXSS) attack. The issue is triggered when handling WebKit Editor commands. This may allow a context-dependent attacker to create a specially crafted web page that will execute arbitrary script code in a user's browser session within the trust relationship between their browser and any website.
 - A type confusion flaw exists in SQLite that is triggered as certain input related to 'snippet' is not properly validated. With specially crafted web content, a context-dependent attacker can corrupt memory and potentially execute arbitrary code.

This product is also affected by vulnerabilities found in the following components:

 - AVEVideoEncoder
 - CoreAudio
 - CoreFoundation
 - Foundation
 - iBooks 
 - IOSurface
 - Kernel
 - TextInput
 - Notifications
 - SQLite
 - WebKit
 - Web Inspector 

Versions of Safari prior to 10.1.1 are affected by multiple vulnerabilities :

 - A use-after-free error exists in the handling of RenderInline objects. With a specially crafted web page, a context-dependent attacker can dereference already freed memory and potentially execute arbitrary code.
 - An unspecified flaw exists in the Safari history menu. With a specially crafted web page, a context-dependent attacker can cause an application denial of service.
 - A flaw exists related to an inconsistent user interface. This may allow a context-dependent attacker to spoof the address bar.
 - A logic flaw exists that allows a UXSS attack. The issue is triggered when handling container nodes. This may allow a context-dependent attacker to create a specially crafted web page that will execute arbitrary script code in a user's browser session within the trust relationship between their browser and any website.
