An issue was discovered in certain Apple products. macOS before 10.12.6 is affected. The issue involves the "kext tools" component. It allows attackers to execute arbitrary code in a privileged context or cause a denial of service (memory corruption) via a crafted app.

The remote host is running a version of Mac OS X version 10.x prior to 10.12.6, and is affected by multiple vulnerabilities :

 - An overflow condition exists in the curl component in the 'dprintf_formatf()' function that is triggered when handling floating point conversion. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2016-9586)
 - A flaw exits in the curl component in the 'randit()' function within file lib/rand.c due to improper initialization of the 32-bit random value, which is used, for example, to generate Digest and NTLM authentication nonces, resulting in weaker cryptographic operations than expected. (CVE-2016-9594)
 - A flaw exists in the curl component in the 'allocate_conn()' function in lib/url.c when using the OCSP stapling feature for checking a X.509 certificate revocation status. The issue is triggered as the request option for OCSP stapling is not properly passed to the TLS library, resulting in no error being returned even when no proof of the validity of the certificate could be provided. A man-in-the-middle attacker can exploit this to provide a revoked certificate. (CVE-2017-2629)
 - A remote code execution vulnerability exists in the CoreAudio component due to improper validation of user-supplied input when handling movie files. An unauthenticated, remote attacker can exploit this, by convincing a user to play a specially crafted movie file, to cause a denial of service condition or the execution of arbitrary code. (CVE-2017-7008)
 - A memory corruption issue exists in the IOUSBFamily component due to improper validation of user-supplied input. A local attacker can exploit this, via a specially crafted application, to cause a denial of service condition or the execution of arbitrary code. (CVE-2017-7009)
 - Multiple out-of-bounds read errors exist in the libxml2 component due to improper handling of specially crafted XML documents. An unauthenticated, remote attacker can exploit these to disclose user information. (CVE-2017-7010, CVE-2017-7013)

 - A remote code execution vulnerability exists in the Audio component due to improper validation of user-supplied input when handling audio files. An unauthenticated, remote attacker can exploit this, by convincing a user to play a specially crafted audio file, to execute arbitrary code. (CVE-2017-7015)
 - Multiple remote code execution vulnerabilities exist in the afclip component due to improper validation of user-supplied input when handling audio files. An unauthenticated, remote attacker can exploit these vulnerabilities, by convincing a user to play a specially crafted audio file, to execute arbitrary code. (CVE-2017-7016, CVE-2017-7033)
 - A memory corruption issue exists in the AppleGraphicsPowerManagement component due to improper validation of input. A local attacker can exploit this to cause a denial of service condition or the execution of arbitrary code with system privileges. (CVE-2017-7021)
 - Multiple memory corruption issues exist in the kernel due to improper validation of input. A local attacker can exploit these issues to cause a denial of service condition or the execution of arbitrary code with system privileges. (CVE-2017-7022, CVE-2017-7024, CVE-2017-7026)
 - Multiple memory corruption issues exist in the kernel due to improper validation of input. A local attacker can exploit these issues to cause a denial of service condition or the execution of arbitrary code with kernel privileges. (CVE-2017-7023, CVE-2017-7025, CVE-2017-7027, CVE-2017-7069)
 - Multiple unspecified flaws exist in the kernel due to a failure to properly sanitize input. A local attacker can exploit these issues, via a specially crafted application, to disclose restricted memory contents. (CVE-2017-7028, CVE-2017-7029, CVE-2017-7067)
 - A flaw exists in the Foundation component due to improper validation of input. A unauthenticated, remote attacker can exploit this, by convincing a user to open specially crafted file, to execute arbitrary code. (CVE-2017-7031)
 - A memory corruption issue exists in the 'kext tools' component due to improper validation of input. A local attacker can exploit this to execute arbitrary code with elevated privileges. (CVE-2017-7032)
 - Multiple unspecified flaws exist in the Intel Graphics Driver component due to a failure to properly sanitize input. A local attacker can exploit these issues, via a specially crafted application, to disclose restricted memory contents. (CVE-2017-7036, CVE-2017-7045)

 - A memory corruption issue exists in the Broadcom BCM43xx family Wi-Fi Chips component that allows an unauthenticated, remote attacker to execute arbitrary code. (CVE-2017-9417)
