Fix Available:  Yes  Vendor Confirmed:  Yes  

Description:   Multiple vulnerabilities were reported in Apple macOS/OS X. A remote user can cause arbitrary code to be executed on the target user's system. A local user can cause denial of service conditions on the target system. A remote or local user can obtain potentially sensitive information. A local user can obtain elevated privileges on the target system. A local user can obtain passwords on the target system.

A remote user can trigger a flaw in apache_mod_php to execute arbitrary code on the target system [CVE-2016-4650].

A local user can trigger a memory corruption error in the Audio component to execute arbitrary code with kernel-level privileges [CVE-2016-4647].

A local user can trigger an out-of-bounds memory read error to determine kernel memory layout [CVE-2016-4648].

A remote user can create a specially crafted audio file that, when loaded by the target user, will trigger an out-of-bounds memory read error and obtain potentially sensitive user information [CVE-2016-4646].

A local user can trigger a null pointer dereference in the Audio function to cause denial of service conditions [CVE-2016-4649].

A local user can trigger a permissions flaw in the processing of web browser cookies to view potentially sensitive information [CVE-2016-4645].

A local user can trigger an out-of-bounds memory read error to view the contents of kernel memory and obtain elevated privileges [CVE-2016-4652].

A local user can trigger a memory corruption error in the Graphics Drivers component to execute arbitrary code with kernel-level privileges [CVE-2016-4634].

A remote user can trigger a memory corruption error in ImageIO and execute arbitrary code [CVE-2016-4629, CVE-2016-4630].

An application can trigger a memory corruption error in the Intel Graphics Driver to execute arbitrary code [CVE-2016-4633].

A local user can trigger a use-after-free memory error in the IOSurface component to execute arbitrary code [CVE-2016-4625].

An application can trigger a memory corruption error in libc++abi to execute arbitrary code with root privileges [CVE-2016-4621].

A remote user can create specially crafted XML to trigger a memory corruption error in libexpat and execute arbitrary code [CVE-2016-0718].

A remote user can create specially crafted XML document that, when processed, will trigger a flaw in libxml2 and access potentially sensitive user information [CVE-2016-4449].

A user can trigger memory corruption errors in libxml2 [CVE-2016-4447, CVE-2016-4448, CVE-2016-4483, CVE-2016-4614, CVE-2016-4615, CVE-2016-4616, CVE-2016-4619].

A user can trigger memory corruption errors in libxslt [CVE-2016-4607, CVE-2016-4608, CVE-2016-4609, CVE-2016-4610, CVE-2016-4612].

An application can trigger a memory corruption error in the Login Window function to execute arbitrary code and obtain potentially sensitive user information [CVE-2016-4640].

An application can trigger a type confusion error in the Login Window function to execute arbitrary code and obtain user information [CVE-2016-4641].

A local user can exploit a memory initialization flaw in the Login Window function and cause denial of service conditions [CVE-2016-4639].

An application can trigger a type confusion error in the Login Window function and gain root privileges [CVE-2016-4638].

A remote user can create a specially crafted FlashPix Bitmap Image that, when loaded by the target user, will trigger a memory corruption error in QuickTime and execute arbitrary code on the target user's system [CVE-2016-4596, CVE-2016-4597, CVE-2016-4600, CVE-2016-4602].

A remote user can create a specially crafted image that, when loaded by the target user, will trigger a memory corruption error in QuickTime and execute arbitrary code on the target user's system [CVE-2016-4598].

A remote user can create a specially crafted SGI file that, when loaded by the target user, will trigger a memory corruption error in QuickTime and execute arbitrary code on the target user's system [CVE-2016-4601].

A remote user can create a specially crafted Photoshop document that, when loaded by the target user, will trigger a memory corruption error in QuickTime and execute arbitrary code on the target user's system [CVE-2016-4599].
