Integer overflow in src/backend/executor/nodeHash.c in PostgreSQL 8.4.1 and earlier, and 8.5 through 8.5alpha2, allows remote authenticated users to cause a denial of service (daemon crash) via a SELECT statement with many LEFT JOIN clauses, related to certain hashtable size calculations.

gdk/gdkwindow.c in GTK+ before 2.18.5, as used in gnome-screensaver before 2.28.1, performs implicit paints on windows of type GDK_WINDOW_FOREIGN, which triggers an X error in certain circumstances and consequently allows physically proximate attackers to bypass screen locking and access an unattended workstation by pressing the Enter key many times.

The gnutls_x509_crt_get_serial function in the GnuTLS library before 1.2.1, when running on big-endian, 64-bit platforms, calls the asn1_read_value with a pointer to the wrong data type and the wrong length value, which allows remote attackers to bypass the certificate revocation list (CRL) check and cause a stack-based buffer overflow via a crafted X.509 certificate, related to extraction of a serial number.

The MMIO instruction decoder in the Xen hypervisor in the Linux kernel 2.6.18 in Red Hat Enterprise Linux (RHEL) 5 allows guest OS users to cause a denial of service (32-bit guest OS crash) via vectors that trigger an unspecified instruction emulation.

A certain Red Hat patch for the Linux kernel in Red Hat Enterprise Linux (RHEL) 4 on the ia64 platform allows local users to use ptrace on an arbitrary process, and consequently gain privileges, via vectors related to a missing ptrace_check_attach call.

smbd in Samba 3.3.11, 3.4.6, and 3.5.0, when libcap support is enabled, runs with the CAP_DAC_OVERRIDE capability, which allows remote authenticated users to bypass intended file permissions via standard filesystem operations with any client.

The gfs2_lock function in the Linux kernel before 2.6.34-rc1-next-20100312, and the gfs_lock function in the Linux kernel on Red Hat Enterprise Linux (RHEL) 5 and 6, does not properly remove POSIX locks on files that are setgid without group-execute permission, which allows local users to cause a denial of service (BUG and system crash) by locking a file on a (1) GFS or (2) GFS2 filesystem, and then changing this file's permissions.

Cross-site scripting (XSS) vulnerability in the tb-send.rb (TrackBack transmission) plugin in tDiary 2.2.2 and earlier allows remote attackers to inject arbitrary web script or HTML via unknown vectors, possibly related to the (1) plugin_tb_url and (2) plugin_tb_excerpt parameters.

The default configuration of cfg.packagepages_actions_excluded in MoinMoin before 1.8.7 does not prevent unsafe package actions, which has unspecified impact and attack vectors.

The design of the dialplan functionality in Asterisk Open Source 1.2.x, 1.4.x, and 1.6.x; and Asterisk Business Edition B.x.x and C.x.x, when using the ${EXTEN} channel variable and wildcard pattern matches, allows context-dependent attackers to inject strings into the dialplan using metacharacters that are injected when the variable is expanded, as demonstrated using the Dial application to process a crafted SIP INVITE message that adds an unintended outgoing channel leg. NOTE: it could be argued that this is not a vulnerability in Asterisk, but a class of vulnerabilities that can occur in any program that uses this feature without the associated filtering functionality that is already available.

WordPress 2.9 before 2.9.2 allows remote authenticated users to read trash posts from other authors via a direct request with a modified p parameter.

MoinMoin before 1.8.7 and 1.9.x before 1.9.2 does not properly sanitize user profiles, which has unspecified impact and attack vectors.

Unspecified vulnerability in MoinMoin 1.5.x through 1.7.x, 1.8.x before 1.8.7, and 1.9.x before 1.9.2 has unknown impact and attack vectors, related to configurations that have a non-empty superuser list, the xmlrpc action enabled, the SyncPages action enabled, or OpenID configured.

MoinMoin 1.9 before 1.9.1 does not perform the expected clearing of the sys.argv array in situations where the GATEWAY_INTERFACE environment variable is set, which allows remote attackers to obtain sensitive information via unspecified vectors.

Stack consumption vulnerability in the ChildProcessSecurityPolicy::CanRequestURL function in browser/child_process_security_policy.cc in Google Chrome before 4.0.249.78 allows remote attackers to cause a denial of service (memory consumption and application crash) via a URL that specifies multiple protocols, as demonstrated by a URL that begins with many repetitions of the view-source: substring.

The ParamTraits<SkBitmap>::Read function in common/common_param_traits.cc in Google Chrome before 4.0.249.78 does not initialize the memory locations that will hold bitmap data, which might allow remote attackers to obtain potentially sensitive information from process memory by providing insufficient data, related to use of a (1) thumbnail database or (2) HTML canvas.

The ParamTraits<SkBitmap>::Read function in common/common_param_traits.cc in Google Chrome before 4.0.249.78 does not use the correct variables in calculations designed to prevent integer overflows, which allows attackers to leverage renderer access to cause a denial of service or possibly have unspecified other impact via bitmap data, related to deserialization.

WebCore/bindings/v8/custom/V8DOMWindowCustom.cpp in WebKit before r52401, as used in Google Chrome before 4.0.249.78, allows remote attackers to bypass the Same Origin Policy via vectors involving the window.open method.

Google Chrome before 4.0.249.78 sends an https URL in the Referer header of an http request in certain circumstances involving https to http redirection, which allows remote HTTP servers to obtain potentially sensitive information via standard HTTP logging.

The image decoder in WebKit before r52833, as used in Google Chrome before 4.0.249.78, does not properly handle a failure of memory allocation, which allows remote attackers to execute arbitrary code in the Chrome sandbox via a malformed GIF file that specifies a large size.
