Adobe Flash Player 10.1.82.76 and earlier on Windows, Mac OS X, Linux, and Solaris and 10.1.92.10 on Android; authplay.dll in Adobe Reader and Acrobat 9.x before 9.4; and authplay.dll in Adobe Reader and Acrobat 8.x before 8.2.5 on Windows and Mac OS X allow remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via unspecified vectors, as exploited in the wild in September 2010.

Mozilla Firefox before 3.5.12 and 3.6.x before 3.6.9, Thunderbird before 3.0.7 and 3.1.x before 3.1.3, and SeaMonkey before 2.0.7 on Mac OS X allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via a crafted font in a data: URL.

Buffer overflow in the Mac_Read_POST_Resource function in base/ftobjs.c in FreeType before 2.4.2 allows remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via a crafted Adobe Type 1 Mac Font File (aka LWFN) font.

FreeType before 2.4.2 uses incorrect integer data types during bounds checking, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted font file.

Array index error in the t42_parse_sfnts function in type42/t42parse.c in FreeType before 2.4.2 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via negative size values for certain strings in FontType42 font files, leading to a heap-based buffer overflow.

The FT_Stream_EnterFrame function in base/ftstream.c in FreeType before 2.4.2 does not properly validate certain position values, which allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted font file.

Heap-based buffer overflow in the Ins_IUP function in truetype/ttinterp.c in FreeType before 2.4.0, when TrueType bytecode support is enabled, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted font file.

Heap-based buffer overflow in the Mac_Read_POST_Resource function in base/ftobjs.c in FreeType before 2.4.0 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted length value in a POST fragment header in a font file.

Integer overflow in the gray_render_span function in smooth/ftgrays.c in FreeType before 2.4.0 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted font file.

Buffer overflow in the Mac_Read_POST_Resource function in base/ftobjs.c in FreeType before 2.4.0 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted LaserWriter PS font file with an embedded PFB fragment.

The psh_glyph_find_strong_points function in pshinter/pshalgo.c in FreeType before 2.4.0 does not properly implement hinting masks, which allows remote attackers to cause a denial of service (heap memory corruption and application crash) or possibly execute arbitrary code via a crafted font file that triggers an invalid free operation.

Integer underflow in glyph handling in FreeType before 2.4.0 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted font file.

The Common Language Runtime (CLR) in Microsoft .NET Framework 2.0 SP1, 2.0 SP2, 3.5, 3.5 SP1, and 3.5.1, and Microsoft Silverlight 2 and 3 before 3.0.50611.0 on Windows and before 3.0.41130.0 on Mac OS X, does not properly handle interfaces and delegations to virtual methods, which allows remote attackers to execute arbitrary code via (1) a crafted XAML browser application (aka XBAP), (2) a crafted ASP.NET application, or (3) a crafted .NET Framework application, aka "Microsoft Silverlight and Microsoft .NET Framework CLR Virtual Method Delegate Vulnerability."

Microsoft Silverlight 3 before 3.0.50611.0 on Windows, and before 3.0.41130.0 on Mac OS X, does not properly handle pointers, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and framework outage) via a crafted web site, aka "Microsoft Silverlight Memory Corruption Vulnerability."

Buffer overflow in Apple iTunes before 9.2.1 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted itpc: URL.

Opera before 10.54 on Windows and Mac OS X does not properly enforce permission requirements for widget filesystem access and directory selection, which allows user-assisted remote attackers to create or modify arbitrary files, and consequently execute arbitrary code, via widget File I/O operations.

Cross-site scripting (XSS) vulnerability in Opera before 10.54 on Windows and Mac OS X, and before 10.11 on UNIX platforms, allows remote attackers to inject arbitrary web script or HTML via a data: URI, related to incorrect detection of the "opening site."

Opera before 10.54 on Windows and Mac OS X, and before 10.60 on UNIX platforms, does not properly restrict access to the full pathname of a file selected for upload, which allows remote attackers to obtain potentially sensitive information via unspecified DOM manipulations.

Opera before 10.54 on Windows and Mac OS X, and before 10.60 on UNIX platforms, does not properly restrict certain uses of homograph characters in domain names, which makes it easier for remote attackers to spoof IDN domains via unspecified choices of characters.

Opera before 10.50 on Windows, before 10.52 on Mac OS X, and before 10.60 on UNIX platforms makes widget properties accessible to third-party domains, which allows remote attackers to obtain potentially sensitive information via a crafted web site.
