kernel: xen: grant table entry swaps have inadequate bounds checking

The GNTTABOP_swap_grant_ref sub-operation in the grant table hypercall in Xen 4.2 and Citrix XenServer 6.0.2 allows local guest kernels or administrators to cause a denial of service (host crash) and possibly gain privileges via a crafted grant reference that triggers a write to an arbitrary hypervisor memory location.

(nnrpd): Prone to STARTTLS plaintext command injection

The STARTTLS implementation in nnrpd in INN before 2.5.3 does not properly restrict I/O buffering, which allows man-in-the-middle attackers to insert commands into encrypted sessions by sending a cleartext command that is processed after TLS is in place, related to a "plaintext command injection" attack, a similar issue to CVE-2011-0411.

dbus: privilege escalation when libdbus is used in setuid/setgid application

libdbus 1.5.x and earlier, when used in setuid or other privileged programs in X.org and possibly other products, allows local users to gain privileges and execute arbitrary code via the DBUS_SYSTEM_BUS_ADDRESS environment variable. NOTE: libdbus maintainers state that this is a vulnerability in the applications that do not cleanse environment variables, not in libdbus itself: "we do not support use of libdbus in setuid binaries that do not sanitize their environment before their first call into libdbus."

Opera before 11.65 does not ensure that the address field corresponds to the displayed web page during blocked navigation, which makes it easier for remote attackers to conduct spoofing attacks by detecting and preventing attempts to load a different web page.

The Crowbar Ohai plugin (chef/cookbooks/ohai/files/default/plugins/crowbar.rb) in the Deployer Barclamp in Crowbar, possibly 1.4 and earlier, allows local users to execute arbitrary shell commands via vectors related to "insecure handling of tmp files" and predictable file names.

Keystone: Lack of authorization for adding users to tenants

OpenStack Keystone, as used in OpenStack Folsom before folsom-rc1 and OpenStack Essex (2012.1), allows remote attackers to add an arbitrary user to an arbitrary tenant via a request to update the user's default tenant to the administrative API. NOTE: this identifier was originally incorrectly assigned to an open redirect issue, but the correct identifier for that issue is CVE-2012-3540.

Web: Bypass of security constraints

org/apache/catalina/realm/RealmBase.java in Apache Tomcat 6.x before 6.0.36 and 7.x before 7.0.30, when FORM authentication is used, allows remote attackers to bypass security-constraint checks by leveraging a previous setUserPrincipal call and then placing /j_security_check at the end of a URI.

Opera before 11.65 does not properly restrict the reading of JSON strings, which allows remote attackers to perform cross-domain loading of JSON resources and consequently obtain sensitive information via a crafted web site.

Opera before 11.65 does not ensure that the address field corresponds to the displayed web page during unusually timed changes to this field, which makes it easier for user-assisted remote attackers to conduct spoofing attacks via vectors involving navigation, reloads, and redirects.

Unrestricted file upload vulnerability in uploader.php in the RBX Gallery plugin 2.1 for WordPress allows remote attackers to execute arbitrary code by uploading a file with an executable extension, then accessing it via a direct request to the file in uploads/rbxslider.

Unrestricted file upload vulnerability in php/upload.php in the wpStoreCart plugin before 2.5.30 for WordPress allows remote attackers to execute arbitrary code by uploading a file with an executable extension, then accessing it via a direct request to the file in uploads/wpstorecart.

Unrestricted file upload vulnerability in doupload.php in the Nmedia Member Conversation plugin before 1.4 for WordPress allows remote attackers to execute arbitrary code by uploading a file with an executable extension, then accessing it via a direct request to the file in wp-content/uploads/user_uploads.

Unrestricted file upload vulnerability in html/Upload.php in the FCChat Widget plugin 2.2.13.1 and earlier for WordPress allows remote attackers to execute arbitrary code by uploading a file with a file with an executable extension followed by a safe extension, then accessing it via a direct request to the file in html/images.

Symantec Messaging Gateway (SMG) before 10.0 has a default password for an unspecified account, which makes it easier for remote attackers to obtain privileged access via an SSH session.

Symantec PGP Universal Server 3.2.x before 3.2.1 MP2 does not properly manage sessions that include key search requests, which might allow remote attackers to read a private key in opportunistic circumstances by making a request near the end of a user's session.

WebKit in Apple Safari before 6.0 does not properly handle drag-and-drop events, which allows user-assisted remote attackers to read arbitrary files via a crafted web site.

WebKit in Apple Safari before 6.0 does not properly handle file: URLs, which allows remote attackers to bypass intended sandbox restrictions and read arbitrary files by leveraging a WebProcess compromise.

Apple Xcode before 4.4 does not properly compose a designated requirement (DR) during signing of programs that lack bundle identifiers, which allows remote attackers to read keychain entries via a crafted app, as demonstrated by the keychain entries of a (1) helper tool or (2) command-line tool.

struts2: Long parameter name DoS

Apache Struts 2.0.0 through 2.3.4 allows remote attackers to cause a denial of service (CPU consumption) via a long parameter name, which is processed as an OGNL expression.

repository/repository_ajax.php in Moodle 2.2.x before 2.2.5 and 2.3.x before 2.3.2 allows remote authenticated users to bypass intended upload-size restrictions via a -1 value in the maxbytes field.
