Cross-site scripting (XSS) vulnerability in Joomla! 1.5.x before 1.5.21 and 1.6.x before 1.6.1 allows remote attackers to inject arbitrary web script or HTML via vectors involving "multiple encoded entities," as demonstrated by the query string to index.php in the com_weblinks or com_content component.

libpurple in Pidgin before 2.7.4 does not properly validate the return value of the purple_base64_decode function, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and application crash) via a crafted message, related to the plugins for MSN, MySpaceIM, XMPP, and Yahoo! and the NTLM authentication support.

Stack consumption vulnerability in the filter_var function in PHP 5.2.x through 5.2.14 and 5.3.x through 5.3.3, when FILTER_VALIDATE_EMAIL mode is used, allows remote attackers to cause a denial of service (memory consumption and application crash) via a long e-mail address 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.

The serialization implementation in JBoss Drools in Red Hat JBoss Enterprise Application Platform (aka JBoss EAP or JBEAP) 4.3 before 4.3.0.CP09 and JBoss Enterprise SOA Platform 4.2 and 4.3 supports the embedding of class files, which allows remote attackers to execute arbitrary code via a crafted static initializer.

plugins/acl/acl-backend-vfile.c in Dovecot 1.2.x before 1.2.15 and 2.0.x before 2.0.5 interprets an ACL entry as a directive to add to the permissions granted by another ACL entry, instead of a directive to replace the permissions granted by another ACL entry, in certain circumstances involving more specific entries that occur after less specific entries, which allows remote authenticated users to bypass intended access restrictions via a request to read or modify a mailbox.

plugins/acl/acl-backend-vfile.c in Dovecot 1.2.x before 1.2.15 and 2.0.x before 2.0.5 interprets an ACL entry as a directive to add to the permissions granted by another ACL entry, instead of a directive to replace the permissions granted by another ACL entry, in certain circumstances involving the private namespace of a user, which allows remote authenticated users to bypass intended access restrictions via a request to read or modify a mailbox.

The sctp_auth_asoc_get_hmac function in net/sctp/auth.c in the Linux kernel before 2.6.36 does not properly validate the hmac_ids array of an SCTP peer, which allows remote attackers to cause a denial of service (memory corruption and panic) via a crafted value in the last element of this array.

The FoFiType1::parse function in fofi/FoFiType1.cc in the PDF parser in xpdf before 3.02pl5, poppler 0.8.7 and possibly other versions up to 0.15.1, kdegraphics, and possibly other products allows context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a PDF file with a crafted PostScript Type1 font that contains a negative array index, which bypasses input validation and triggers memory corruption.

The PostScriptFunction::PostScriptFunction function in poppler/Function.cc in the PDF parser in poppler 0.8.7 and possibly other versions up to 0.15.1, and possibly other products, allows context-dependent attackers to cause a denial of service (crash) via a PDF file that triggers an uninitialized pointer dereference.

The Gfx::getPos function in the PDF parser in xpdf before 3.02pl5, poppler 0.8.7 and possibly other versions up to 0.15.1, CUPS, kdegraphics, and possibly other products allows context-dependent attackers to cause a denial of service (crash) via unknown vectors that trigger an uninitialized pointer dereference.

lib/MessageStoreImpl.cpp in Red Hat Enterprise MRG before 1.2.2 allows remote authenticated users to cause a denial of service (stack memory exhaustion and broker crash) via a large persistent message.

VMware SpringSource Spring Security 2.x before 2.0.6 and 3.x before 3.0.4, and Acegi Security 1.0.0 through 1.0.7, as used in IBM WebSphere Application Server (WAS) 6.1 and 7.0, allows remote attackers to bypass security constraints via a path parameter.

The backend driver in Xen 3.x allows guest OS users to cause a denial of service via a kernel thread leak, which prevents the device and guest OS from being shut down or create a zombie domain, causes a hang in zenwatch, or prevents unspecified xm commands from working properly, related to (1) netback, (2) blkback, or (3) blktap.

The KVM implementation in the Linux kernel before 2.6.36 does not properly reload the FS and GS segment registers, which allows host OS users to cause a denial of service (host OS crash) via a KVM_RUN ioctl call in conjunction with a modified Local Descriptor Table (LDT).

The wait_for_child_to_die function in main/event.c in FreeRADIUS 2.1.x before 2.1.10, in certain circumstances involving long-term database outages, does not properly handle long queue times for requests, which allows remote attackers to cause a denial of service (daemon crash) by sending many requests.

The fr_dhcp_decode function in lib/dhcp.c in FreeRADIUS 2.1.9, in certain non-default builds, does not properly handle the DHCP Relay Agent Information option, which allows remote attackers to cause a denial of service (infinite loop and daemon outage) via a packet that has more than one sub-option. NOTE: some of these details are obtained from third party information.

Cross-site scripting (XSS) vulnerability in fetchmailprefs.php in Horde IMP before 4.3.8, and Horde Groupware Webmail Edition before 1.2.7, allows remote attackers to inject arbitrary web script or HTML via the fm_id parameter in a fetchmail_prefs_save action, related to the Fetchmail configuration.

Cross-site request forgery (CSRF) vulnerability in the Horde Application Framework before 3.3.9 allows remote attackers to hijack the authentication of unspecified victims for requests to a preference form.

Cross-site scripting (XSS) vulnerability in Horde Dynamic IMP (DIMP) before 1.1.5, and Horde Groupware Webmail Edition before 1.2.7, allows remote attackers to inject arbitrary web script or HTML via vectors related to displaying mailbox names.
