Heap-based buffer overflow in the __nss_hostname_digits_dots function in glibc 2.2, and other 2.x versions before 2.18, allows context-dependent attackers to execute arbitrary code via vectors related to the (1) gethostbyname or (2) gethostbyname2 function, aka "GHOST."

Unspecified vulnerability in Adobe Flash Player through 13.0.0.262 and 14.x, 15.x, and 16.x through 16.0.0.287 on Windows and OS X and through 11.2.202.438 on Linux allows remote attackers to execute arbitrary code via unknown vectors, as exploited in the wild in January 2015.

Adobe Flash Player before 13.0.0.262 and 14.x through 16.x before 16.0.0.287 on Windows and OS X and before 11.2.202.438 on Linux does not properly restrict discovery of memory addresses, which allows attackers to bypass the ASLR protection mechanism on Windows, and have an unspecified impact on other platforms, via unknown vectors, as exploited in the wild in January 2015.

Buffer overflow in the png_read_IDAT_data function in pngrutil.c in libpng before 1.5.21 and 1.6.x before 1.6.16 allows context-dependent attackers to execute arbitrary code via IDAT data with a large width, a different vulnerability than CVE-2014-9495.

The darwinssl_connect_step1 function in lib/vtls/curl_darwinssl.c in libcurl 7.31.0 through 7.39.0, when using the DarwinSSL (aka SecureTransport) back-end for TLS, does not check if a cached TLS session validated the certificate when reusing the session, which allows man-in-the-middle attackers to spoof servers via a crafted certificate.

Heap-based buffer overflow in the png_combine_row function in libpng before 1.5.21 and 1.6.x before 1.6.16, when running on 64-bit systems, might allow context-dependent attackers to execute arbitrary code via a "very wide interlaced" PNG image.

Double free vulnerability in the zend_ts_hash_graceful_destroy function in zend_ts_hash.c in the Zend Engine in PHP through 5.5.20 and 5.6.x through 5.6.4 allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors.

The HTTP clients in the (1) httplib, (2) urllib, (3) urllib2, and (4) xmlrpclib libraries in CPython (aka Python) 2.x before 2.7.9 and 3.x before 3.4.3, when accessing an HTTPS URL, do not (a) check the certificate against a trust store or verify that the server hostname matches a domain name in the subject's (b) Common Name or (c) subjectAltName field of the X.509 certificate, which allows man-in-the-middle attackers to spoof SSL servers via an arbitrary valid certificate.

cURL and libcurl before 7.38.0 allow remote attackers to bypass the Same Origin Policy and set cookies for arbitrary sites by setting a cookie for a top-level domain.

cURL and libcurl before 7.38.0 does not properly handle IP addresses in cookie domain names, which allows remote attackers to set cookies for or send arbitrary cookies to certain sites, as demonstrated by a site at 192.168.0.1 setting cookies for a site at 127.168.0.1.

The kernel in Apple iOS before 8.1.1 and Apple TV before 7.0.2 does not properly validate IOSharedDataQueue object metadata, which allows attackers to execute arbitrary code in a privileged context via a crafted application.

CFNetwork in Apple iOS before 8.1.1 and OS X before 10.10.1 does not properly clear the browsing cache upon a transition out of private-browsing mode, which makes it easier for physically proximate attackers to obtain sensitive information by reading cache files.

Use-after-free vulnerability in WebKit, as used in Apple OS X before 10.10.1, allows remote attackers to execute arbitrary code via crafted page objects in an HTML document.

The "System Profiler About This Mac" component in Apple OS X before 10.10.1 includes extraneous cookie data in system-model requests, which might allow remote attackers to obtain sensitive information via unspecified vectors.

Apple iOS before 8.1.1 and OS X before 10.10.1 include location data during establishment of a Spotlight Suggestions server connection by Spotlight or Safari, which might allow remote attackers to obtain sensitive information via unspecified vectors.

parser.c in libxml2 before 2.9.2 does not properly prevent entity expansion even when entity substitution has been disabled, which allows context-dependent attackers to cause a denial of service (CPU consumption) via a crafted XML document containing a large number of nested entity references, a variant of the "billion laughs" attack.

SecurityAgent in Apple OS X before 10.10 does not ensure that a Kerberos ticket is in the cache for the correct user, which allows local users to gain privileges in opportunistic circumstances by leveraging a Fast User Switching login.

Apple OS X before 10.10 allows remote attackers to cause a denial of service (NULL pointer dereference) via crafted ASN.1 data.

The kernel in Apple OS X before 10.10 allows local users to cause a denial of service (panic) via a message to a system control socket.

NetFS Client Framework in Apple OS X before 10.10 does not ensure that the disabling of File Sharing is always possible, which allows remote attackers to read or write to files by leveraging a state in which File Sharing is permanently enabled.
