Apple OS X before 10.11 does not ensure that the keychain's lock state is displayed correctly, which has unspecified impact and attack vectors.

The EFI component in Apple OS X before 10.11 allows physically proximate attackers to modify firmware during the EFI update process by inserting an Apple Ethernet Thunderbolt adapter with crafted code in an Option ROM, aka a "Thunderstrike" issue. NOTE: this issue exists because of an incomplete fix for CVE-2014-4498.

Heimdal, as used in Apple OS X before 10.11, allows remote attackers to conduct replay attacks against the SMB server via packet data that represents a Kerberos authenticated request.

The debugging feature in the kernel in Apple OS X before 10.11 mismanages state, which allows local users to cause a denial of service via unspecified vectors.

The Secure Empty Trash feature in Finder in Apple OS X before 10.11 improperly deletes Trash files, which might allow local users to obtain sensitive information by reading storage media, as demonstrated by reading a flash drive.

The protected range register in the EFI component in Apple OS X before 10.11 has an incorrect value, which allows attackers to cause a denial of service (boot failure) via a crafted app that writes to an unintended address.

The Address Book framework in Apple OS X before 10.11 allows local users to gain privileges by using an environment variable to inject code into processes that rely on this framework.

The X.509 certificate-trust implementation in Apple OS X before 10.11 does not recognize that the kSecRevocationRequirePositiveResponse flag implies a revocation-checking requirement, which makes it easier for man-in-the-middle attackers to spoof endpoints by leveraging access to a revoked certificate.

SMBClient in SMB in Apple OS X before 10.11 allows local users to obtain sensitive kernel memory-layout information via unspecified vectors.

The SMB implementation in the kernel in Apple OS X before 10.11 allows local users to gain privileges or cause a denial of service (memory corruption) via unspecified vectors.

IOGraphics in Apple OS X before 10.11 allows local users to gain privileges or cause a denial of service (memory corruption) via unspecified vectors, a different vulnerability than CVE-2015-5871, CVE-2015-5872, and CVE-2015-5873.

rsh in the remote_cmds component in Apple OS X before 10.11 allows local users to obtain root privileges via vectors involving environment variables.

The Install Framework Legacy component in Apple OS X before 10.11 allows local users to obtain root privileges via vectors involving a privileged executable file.

The TLS Handshake Protocol implementation in Secure Transport in Apple OS X before 10.11 accepts a Certificate Request message within a session in which no Server Key Exchange message has been sent, which allows remote attackers to have an unspecified impact via crafted TLS data.

The Mail Drop feature in Mail in Apple OS X before 10.11 mishandles encryption parameters for attachments, which makes it easier for remote attackers to obtain sensitive information by sniffing the network during transmission of an S/MIME e-mail message with a large attachment.

The bidirectional text-display and text-selection implementations in Terminal in Apple OS X before 10.11 interpret directional override formatting characters differently, which allows remote attackers to spoof the content of a text document via a crafted character sequence.

Notes in Apple OS X before 10.11 misparses links, which allows local users to obtain sensitive information via unspecified vectors.

The Intel Graphics Driver component in Apple OS X before 10.11 allows local users to gain privileges or cause a denial of service (memory corruption) via unspecified vectors, a different vulnerability than CVE-2015-5830.

Cross-site scripting (XSS) vulnerability in Notes in Apple OS X before 10.11 allows local users to inject arbitrary web script or HTML via crafted text.

IOGraphics in Apple OS X before 10.11 allows local users to gain privileges or cause a denial of service (memory corruption) via unspecified vectors, a different vulnerability than CVE-2015-5871, CVE-2015-5872, and CVE-2015-5890.
