icu: heap overflow via incorrect isolateCount

The resolveImplicitLevels function in common/ubidi.c in the Unicode Bidirectional Algorithm implementation in ICU4C in International Components for Unicode (ICU) before 55.1 does not properly track directionally isolated pieces of text, which allows remote attackers to cause a denial of service (heap-based buffer overflow) or possibly execute arbitrary code via crafted text.

The Disk Images subsystem in Apple iOS before 9.3.2, OS X before 10.11.5, tvOS before 9.2.1, and watchOS before 2.2.1 allows attackers to execute arbitrary code in a privileged context or cause a denial of service (memory corruption) via a crafted app.

Race condition in the Disk Images subsystem in Apple iOS before 9.3.2, OS X before 10.11.5, tvOS before 9.2.1, and watchOS before 2.2.1 allows local users to obtain sensitive information from kernel memory via unspecified vectors.

IOStorageFamily in Apple iOS before 9 does not properly initialize an unspecified data structure, which allows local users to obtain sensitive information from kernel memory via unknown vectors.

CoreCapture in Apple iOS before 9.3.2, OS X before 10.11.5, tvOS before 9.2.1, and watchOS before 2.2.1 allows attackers to execute arbitrary code in a privileged context or cause a denial of service (NULL pointer dereference) via a crafted app.

Heap-based buffer overflow in the DNS client library in configd in Apple iOS before 9.1, OS X before 10.11.1, and watchOS before 2.0.1 allows attackers to execute arbitrary code via a crafted app that sends a spoofed configd response to a client.

IOAcceleratorFamily in Apple iOS before 9 allows attackers to obtain sensitive kernel memory-layout information via a crafted app.

CCCrypt in CommonCrypto in Apple iOS before 9.3.2, OS X before 10.11.5, tvOS before 9.2.1, and watchOS before 2.2.1 mishandles return values during key-length calculations, which allows attackers to obtain sensitive information via a crafted app.

Messages in Apple iOS before 9.3, OS X before 10.11.4, and watchOS before 2.2 does not properly implement a cryptographic protection mechanism, which allows remote attackers to read message attachments via vectors related to duplicate messages.

Directory traversal vulnerability in the BOM (aka Bill of Materials) component in Apple iOS before 9.1, OS X before 10.11.1, and watchOS before 2.0.1 allows remote attackers to execute arbitrary code via a crafted CPIO archive.

TrueTypeScaler in Apple iOS before 9.3, OS X before 10.11.4, tvOS before 9.2, and watchOS before 2.2 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted font file.

Data Detectors Engine in Apple iOS before 9 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted text file.

AppSandbox in Apple iOS before 9.2, OS X before 10.11.2, tvOS before 9.1, and watchOS before 2.1 mishandles hard links, which allows attackers to bypass Contacts access revocation via a crafted app.

The Audio component in Apple iOS before 9 allows remote attackers to cause a denial of service (memory corruption and application crash) via a crafted audio file.

libxml2 in Apple iOS before 9.3, OS X before 10.11.4, and watchOS before 2.2 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via a crafted XML document.

The kernel in Apple iOS before 9.3, OS X before 10.11.4, tvOS before 9.2, and watchOS before 2.2 allows attackers to execute arbitrary code in a privileged context or cause a denial of service (memory corruption) via a crafted app, a different vulnerability than CVE-2016-1754.

The X.509 certificate-trust implementation in Apple iOS before 9.1 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.

The kernel in Apple iOS before 9.3, OS X before 10.11.4, tvOS before 9.2, and watchOS before 2.2 allows attackers to execute arbitrary code in a privileged context or cause a denial of service (memory corruption) via a crafted app, a different vulnerability than CVE-2016-1755.

The CFNetwork HTTPProtocol component in Apple iOS before 9 mishandles HSTS state, which allows remote attackers to bypass the Safari private-browsing protection mechanism and track users via a crafted web site.

sqlite: invalid free() in src/vdbe.c

The sqlite3VdbeExec function in vdbe.c in SQLite before 3.8.9 does not properly implement comparison operators, which allows context-dependent attackers to cause a denial of service (invalid free operation) or possibly have unspecified other impact via a crafted CHECK clause, as demonstrated by CHECK(0&O>O) in a CREATE TABLE statement.
