WebKit, as used in Google Chrome before 4.0.249.78 and Apple Safari, allows remote attackers to bypass intended restrictions on popup windows via crafted use of a mouse click event.
Devin Carraway of the Debian Security Team discovered that the upstream fix for the CVE-2008-2079 is incomplete and still makes it possible for local users to create tables via INDEX/DATA DIRECTORY directives in the MySQL data directory (/var/lib/mysql) via directory symlinks.
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=480292#25
CVE-2008-2079 was tracked via bug bug #445222.
An attacker needs following to exploit this issue: - MySQL database account with privileges to create tables - shell access to the host running MySQL database with write access to a directory accessible by the mysqld daemon process
Heap-based buffer overflow in pcrecompile.c in the Perl-Compatible Regular Expression (PCRE) library 7.7 allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via a regular expression that begins with an option and contains multiple branches.
Will Drewry of the Google Security Team created a set of fuzzed OGG test files to test OGG Vorbis and Tremor implementations. Some of them were causing memory corruption and crash on old libvorbis versions (prior to 1.0).
Crash / corruption occurred in makedecodetree(). This function was removed prior to the release of upstream version 1.0 in following changes:
https://trac.xiph.org/changeset/2959 https://trac.xiph.org/changeset/2960
Test files do not crash libvobis revision 2960 or later.
The pollmodeio file for the megaraidsas driver in the Linux kernel 2.6.31.6 and earlier has world-writable permissions, which allows local users to change the I/O mode of the driver by modifying this file.
The connector layer in the Linux kernel before 2.6.31.5 does not require the CAPSYSADMIN capability for certain interaction with the (1) uvesafb, (2) pohmelfs, (3) dst, or (4) dm subsystem, which allows local users to bypass intended access restrictions and gain privileges via calls to functions in these subsystems.
net/unix/afunix.c in the Linux kernel 2.6.31.4 and earlier allows local users to cause a denial of service (system hang) by creating an abstract-namespace AFUNIX listening socket, performing a shutdown operation on this socket, and then performing a series of connect operations to this socket.
Multiple race conditions in fs/pipe.c in the Linux kernel before 2.6.32-rc6 allow local users to cause a denial of service (NULL pointer dereference and system crash) or gain privileges by attempting to open an anonymous pipe via a /proc//fd/ pathname.
Use-after-free vulnerability in the abstract file-descriptor handling interface in the cupsdDoSelect function in scheduler/select.c in the scheduler in cupsd in CUPS 1.3.7 and 1.3.10 allows remote attackers to cause a denial of service (daemon crash or hang) via a client disconnection during listing of a large number of print jobs, related to improperly maintaining a reference count. NOTE: some of these details are obtained from third party information.
Quote from http://patchwork.ozlabs.org/patch/35412/: Commit 9ef1d4c7c7aca1cd436612b6ca785b726ffb8ed8 introduced a typo in initialization.
Quoting from the upstream commit: Almost all r128's private ioctls require that the CCE state has already been initialised. However, most do not test that this has been done, and will proceed to dereference a null pointer. This may result in a security vulnerability, since some ioctls are unprivileged.
This adds a macro for the common initialisation test and changes all ioctl implementations that require prior initialisation to use that macro.
Also, r128doinitcce() does not test that the CCE state has not been initialised already. Repeated initialisation may lead to a crash or resource leak. This adds that test.

Array index error in the gdthreadevent function in drivers/scsi/gdth.c in the Linux kernel before 2.6.32-rc8 allows local users to cause a denial of service or possibly gain privileges via a negative event index in an IOCTL request.
arch/x86/ia32/ia32entry.S in the Linux kernel before 2.6.31.4 on the x8664 platform does not clear certain kernel registers before a return to user mode, which allows local users to read register values from an earlier process by switching an ia32 process to 64-bit mode.
The WebKit component in Safari in Apple iPhone OS before 3.1, and iPhone OS before 3.1.1 for iPod touch, does not remove usernames and passwords from URLs sent in Referer headers, which allows remote attackers to obtain sensitive information by reading Referer logs on a web server.
libxml2 before 2.7.8, as used in Google Chrome before 7.0.517.44, Apple Safari 5.0.2 and earlier, and other products, reads from invalid memory locations during processing of malformed XPath expressions, which allows context-dependent attackers to cause a denial of service (application crash) via a crafted XML document.
The utf8decode function in PHP before 5.3.4 does not properly handle non-shortest form UTF-8 encoding and ill-formed subsequences in UTF-8 data, which makes it easier for remote attackers to bypass cross-site scripting (XSS) and SQL injection protection mechanisms via a crafted string.
The ZipArchive::getArchiveComment function in PHP 5.2.x through 5.2.14 and 5.3.x through 5.3.3 allows context-dependent attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted ZIP archive.
fopenwrappers.c in PHP 5.3.x through 5.3.3 might allow remote attackers to bypass openbasedir restrictions via vectors related to the length of a filename.
Use-after-free vulnerability in WebKit, as used in Apple Safari before 4.1.3 and 5.0.x before 5.0.3, Google Chrome before 6.0.472.53, and webkitgtk before 1.2.6, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via vectors involving element focus.
Google Chrome before 6.0.472.53 does not properly restrict copying to the clipboard, which has unspecified impact and attack vectors.
WebKit, as used in Apple Safari before 4.1.3 and 5.0.x before 5.0.3, Google Chrome before 6.0.472.53, and webkitgtk before 1.2.6, does not properly restrict read access to images derived from CANVAS elements, which allows remote attackers to bypass the Same Origin Policy and obtain potentially sensitive image data via a crafted web site.
The implementation of the Unicode Bidirectional Algorithm (aka Bidi algorithm or UBA) in Google Chrome before 5.0.375.99 allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via unknown vectors.
Google Chrome before 5.0.375.99 allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via an invalid SVG document.
Heap-based buffer overflow in the InsIUP 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.
Buffer overflow in ftmulti.c in the ftmulti demo program in FreeType before 2.4.2 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted font file.
Multiple buffer overflows in demo programs in FreeType before 2.4.0 allow 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 MacReadPOSTResource 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.
Robert Swiecki reported an invalid free flaw, that could possibly corrupt the heap, in freetype. This could cause applications linked against freetype to crash (SIGABRT) or, possibly, lead to the execution of arbitrary code if an attacker were able to get a victim to load a malicious font file.
The affected code is not present in Red Hat Enterprise Linux 3 (freetype 2.1.4). In Red Hat Enterprise Linux 4 and 5 this code is present, but does not cause a crash.
This issue has been given the name CVE-2010-2498.
