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.
methods/https.cc in apt before 0.8.11 accepts connections when the certificate host name fails validation and Verify-Host is enabled, which allows man-in-the-middle attackers to obtain repository credentials via unspecified vectors.
The jpccrggetparms function in libjasper/jpc/jpccs.c in JasPer 1.900.1 uses an incorrect data type during a certain size calculation, which allows remote attackers to trigger a heap-based buffer overflow and execute arbitrary code, or cause a denial of service (heap memory corruption), via a crafted component registration (CRG) marker segment in a JPEG2000 file.
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.
MySQL before 5.1.48 allows remote authenticated users with alter database privileges to cause a denial of service (server crash and database loss) via an ALTER DATABASE command with a #mysql50# string followed by a . (dot), .. (dot dot), ../ (dot dot slash) or similar sequence, and an UPGRADE DATA DIRECTORY NAME command, which causes MySQL to move certain directories to the server data directory.
An off by one memory read out of bounds issue exists in WebKit's handling of HTML lists. Visiting a maliciously crafted website may lead to an unexpected application termination or the disclosure of the contents of memory. This issue is addressed through improved bounds checking.

Double free vulnerability in WebKit in Apple iOS before 4.1 on the iPhone and iPod touch allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via vectors related to the rendering of an inline element.
Use-after-free vulnerability in WebKit in Apple iOS before 4.1 on the iPhone and iPod touch, and webkitgtk before 1.2.6, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via vectors involving scrollbars.
Use-after-free vulnerability in WebKit in Apple iOS before 4.1 on the iPhone and iPod touch, and webkitgtk before 1.2.6, allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via vectors involving selections.
WebKit in Apple iOS before 4.1 on the iPhone and iPod touch, and webkitgtk before 1.2.6, allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via vectors involving form menus.
The X.Org X wrapper (xserver-wrapper.c) in Debian GNU/Linux and Ubuntu Linux does not properly verify the TTY of a user who is starting X, which allows local users to bypass intended access restrictions by associating stdin with a file that is misinterpreted as the console TTY.
Integer overflow in the exifprocessIFDTAG function in exif.c in the exif extension in PHP 5.4.0beta2 on 32-bit platforms allows remote attackers to read the contents of arbitrary memory locations or cause a denial of service via a crafted offsetval value in an EXIF header in a JPEG file, a different vulnerability than CVE-2011-0708.
A number of vulnerabilities were found and reported by CERT in JasPer which may allow a remote unauthenticated attacker to execute arbitrary code.

Deepak Bhole discovered a flaw in the Same Origin Policy (SOP) implementation in the IcedTea project Web browser plugin. A malicious applet could use this flaw to bypass SOP protection and open connections to any sub-domain of the second-level domain of the applet's origin, as well as any sub-domain of the domain that is the suffix of the origin second-level domain. For example, IcedTea-Web plugin allowed applet from some.host.example.com to connect to other.host.example.com, www.example.com, and example.com, as well as www.ample.com or ample.com.
Software Center in Ubuntu 11.10, 11.04 10.10 does not properly validate server certificates, which allows remote attackers to execute arbitrary code or obtain sensitive information via a man-in-the-middle (MITM) attack.
The server in ISC DHCP 3.x and 4.x before 4.2.2, 3.1-ESV before 3.1-ESV-R3, and 4.1-ESV before 4.1-ESV-R3 allows remote attackers to cause a denial of service (daemon exit) via a crafted DHCP packet.
Buffer overflow in libpng 1.0.x before 1.0.55, 1.2.x before 1.2.45, 1.4.x before 1.4.8, and 1.5.x before 1.5.4, when used by an application that calls the pngrgbtogray function but not the pngsetexpand function, allows remote attackers to overwrite memory with an arbitrary amount of data, and possibly have unspecified other impact, via a crafted PNG image.
It was found that libpng read uninitialized memory when it encountered a sCAL chunk that is empty, and improperly handles a sCAL chunk that lacks the terminating zero between the two strings that it conveys.
This was fixed in libpng-1.5.4, libpng-1.4.8, libpng-1.2.45, and libpng-1.0.55.
Patch: http://libpng.git.sourceforge.net/git/gitweb.cgi?p=libpng/libpng;a=commitdiff;h=61a2d8a2a7b03023e63eae9a3e64607aaaa6d339
Cross-site scripting (XSS) vulnerability in the chgpasswd function in web/swat.c in the Samba Web Administration Tool (SWAT) in Samba 3.x before 3.5.10 allows remote authenticated administrators to inject arbitrary web script or HTML via the username parameter to the passwd program (aka the user field to the Change Password page).
A path traversal flaw was found in the way Ark, the tool for managing various archive formats within the KDE environment, processed certain Zip archives. A remote attacker could provide a specially-crafted Zip archive, which once opened in the Ark GUI frontend would lead to arbitrary file being opened or, potentially, if the local victim provided correct user credentials could allow that file to be removed.
