Messages in Apple iOS before 6, when multiple iMessage e-mail addresses are configured, does not ensure that a reply's sender address matches the recipient address of the original message, which allows remote attackers to obtain potentially sensitive information about alternate e-mail addresses in opportunistic circumstances by reading a reply.

Mail in Apple iOS before 6 uses an S/MIME message's From address as the displayed sender address, which allows remote attackers to spoof signed content via an e-mail message in which the From field does not match the signer's identity.

Mail in Apple iOS before 6 does not properly implement the Data Protection feature for e-mail attachments, which allows physically proximate attackers to bypass an intended passcode requirement via unspecified vectors.

Mail in Apple iOS before 6 does not properly handle reuse of Content-ID header values, which allows remote attackers to spoof attachments via a header value that was also used in a previous e-mail message, as demonstrated by a message from a different sender.

The Berkeley Packet Filter (BPF) interpreter implementation in the kernel in Apple iOS before 6 accesses uninitialized memory locations, which allows local users to obtain sensitive information about the layout of kernel memory via a crafted program that uses a BPF interface.

The kernel in Apple iOS before 6 dereferences invalid pointers during the handling of packet-filter data structures, which allows local users to gain privileges via a crafted program that makes packet-filter ioctl calls.

Buffer overflow in the IPsec component in Apple iOS before 6 allows remote attackers to execute arbitrary code via a crafted racoon configuration file.

Double free vulnerability in ImageIO in Apple iOS before 6 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted JPEG image.

The DNAv4 protocol implementation in the DHCP component in Apple iOS before 6 sends Wi-Fi packets containing a MAC address of a host on a previously used network, which might allow remote attackers to obtain sensitive information about previous device locations by sniffing an unencrypted Wi-Fi network for these packets.

CFNetwork in Apple iOS before 6 does not properly identify the host portion of a URL, which allows remote attackers to obtain sensitive information by leveraging the construction of an HTTP request with an incorrect hostname derived from a malformed URL.

The Sorenson codec in QuickTime in Apple Mac OS X before 10.7.5, and in CoreMedia in iOS before 6, accesses uninitialized memory locations, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted movie file with Sorenson encoding.

WebKit, as used in Apple iTunes before 10.7, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted web site, a different vulnerability than other WebKit CVEs listed in APPLE-SA-2012-09-12-1.

WebKit, as used in Apple iTunes before 10.7, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted web site, a different vulnerability than other WebKit CVEs listed in APPLE-SA-2012-09-12-1.

libxml2 2.9.0-rc1 and earlier, as used in Google Chrome before 21.0.1180.89, does not properly support a cast of an unspecified variable during handling of XSL transforms, which allows remote attackers to cause a denial of service or possibly have unknown other impact via a crafted document, related to the _xmlNs data structure in include/libxml/tree.h.

libxslt 1.1.26 and earlier, as used in Google Chrome before 21.0.1180.89, does not properly manage memory, which might allow remote attackers to cause a denial of service (application crash) via a crafted XSLT expression that is not properly identified during XPath navigation, related to (1) the xsltCompileLocationPathPattern function in libxslt/pattern.c and (2) the xsltGenerateIdFunction function in libxslt/functions.c.

Cross-site scripting (XSS) vulnerability in the GoodReader app 3.16 and earlier for iOS on the iPad, and 3.15.1 and earlier for iOS on the iPhone and iPod touch, allows remote attackers to inject arbitrary web script or HTML via vectors involving use of this app in conjunction with a web browser.
