openstack-nova: Boot from volume allows access to random volumes

The boot-from-volume feature in OpenStack Compute (Nova) Folsom and Essex, when using nova-volumes, allows remote authenticated users to boot from other users' volumes via a volume id in the block_device_mapping parameter.

xen: oxenstored incorrect handling of certain Xenbus ring states

oxenstored in Xen 4.1.x, Xen 4.2.x, and xen-unstable does not properly consider the state of the Xenstore ring during read operations, which allows guest OS users to cause a denial of service (daemon crash and host-control outage, or memory consumption) or obtain sensitive control-plane data by leveraging guest administrative access.

sssd: TOCTOU race conditions by copying and removing directory trees

System Security Services Daemon (SSSD) before 1.9.4, when (1) creating, (2) copying, or (3) removing a user home directory tree, allows local users to create, modify, or delete arbitrary files via a symlink attack on another user's files.

The Keyboard Shortcut Utility module 7.x-1.x before 7.x-1.1 for Drupal does not properly check node restrictions, which allows (1) remote authenticated users with the "view shortcuts" permission to read nodes or (2) remote authenticated users with the "admin shortcuts" permission to read, edit, or delete nodes via unspecified vectors.

The printer friendly version functionality in the Book module in Drupal 6.x before 6.28 and 7.x before 7.19 does not properly restrict access to node that are part of a book outline, which allows remote authenticated users with the "access printer-friendly version" permission to read node titles and possibly node content via unspecified vectors.

The Image module in Drupal 7.x before 7.19, when a private file system is used, does not properly restrict access to derivative images, which allows remote attackers to read derivative images of otherwise restricted images via unspecified vectors.

openssl: information leak due to invalid Return value check

RSA verification recovery in the EVP_PKEY_verify_recover function in OpenSSL 1.x before 1.0.0a, as used by pkeyutl and possibly other applications, returns uninitialized memory upon failure, which might allow context-dependent attackers to bypass intended key requirements or obtain sensitive information via unspecified vectors. NOTE: some of these details are obtained from third party information.

qt: QSharedMemory class created shared memory segments with insecure permissions

The QSharedMemory class in Qt 5.0.0, 4.8.x before 4.8.5, 4.7.x before 4.7.6, and other versions including 4.4.0 uses weak permissions (world-readable and world-writable) for shared memory segments, which allows local users to read sensitive information or modify critical program data, as demonstrated by reading a pixmap being sent to an X server.

The email2image module 6.x-1.x and 6.x-2.x for Drupal does not properly restrict access to nodes, which allows remote attackers to read images of user email addresses and email fields.

feed.php in phpBB 3.0.7 before 3.0.7-PL1 does not properly check permissions for feeds, which allows remote attackers to bypass intended access restrictions via unspecified attack vectors related to permission settings on a private forum.

The redirect_stderr function in xnbd_common.c in xnbd-server and xndb-wrapper in xNBD 0.1.0 allow local users to overwrite arbitrary files via a symlink attack on /tmp/xnbd.log.

kernel: x86/msr: /dev/cpu/*/msr local privilege escalation

The msr_open function in arch/x86/kernel/msr.c in the Linux kernel before 3.7.6 allows local users to bypass intended capability restrictions by executing a crafted application as root, as demonstrated by msr32.c.

rubygem-activerecord/rubygem-activemodel: circumvention of attr_protected

ActiveRecord in Ruby on Rails before 2.3.17, 3.1.x before 3.1.11, and 3.2.x before 3.2.12 allows remote attackers to bypass the attr_protected protection mechanism and modify protected model attributes via a crafted request.

sssd: simple access provider flaw prevents intended ACL use when client to an AD provider

The Simple Access Provider in System Security Services Daemon (SSSD) 1.9.0 through 1.9.4, when the Active Directory provider is used, does not properly enforce the simple_deny_groups option, which allows remote authenticated users to bypass intended access restrictions.

The FTP proxy server in Apple AirPort Express, AirPort Extreme, and Time Capsule with firmware 7.5 does not restrict the IP address and port specified in a PORT command from a client, which allows remote attackers to leverage intranet FTP servers for arbitrary TCP forwarding via a crafted PORT command.

Portal: XML eXternal Entity (XXE) flaw in site import

The GateIn Portal export/import gadget in JBoss Enterprise Portal Platform 5.2.2 allows remote attackers to read arbitrary files via a crafted external XML entity in an XML document, aka an XML Entity Expansion (XEE) attack.

The admin page in the Banckle Chat module for Drupal does not properly restrict access, which allows remote attackers to bypass intended restrictions via unspecified vectors.

mysql: table destruction via DATA/INDEX DIRECTORY directives using symlinks

MySQL before 5.1.46 allows local users to delete the data and index files of another user's MyISAM table via a symlink attack in conjunction with the DROP TABLE command, a different vulnerability than CVE-2008-4098 and CVE-2008-7247.

The default configuration of nginx, possibly 1.3.13 and earlier, uses world-readable permissions for the (1) access.log and (2) error.log files, which allows local users to obtain sensitive information by reading the files.

libxml2: CPU consumption DoS and other effects when performing string substitutions during external entities expansion

libxml2 through 2.9.1 does not properly handle external entities expansion unless an application developer uses the xmlSAX2ResolveEntity or xmlSetExternalEntityLoader function, which allows remote attackers to cause a denial of service (resource consumption), send HTTP requests to intranet servers, or read arbitrary files via a crafted XML document, aka an XML External Entity (XXE) issue. NOTE: it could be argued that because libxml2 already provides the ability to disable external entity expansion, the responsibility for resolving this issue lies with application developers; according to this argument, this entry should be REJECTed and each affected application would need its own CVE.
