libspice: Relying on guest provided data structures to indicate memory allocation

libspice, as used in QEMU-KVM in the Hypervisor (aka rhev-hypervisor) in Red Hat Enterprise Virtualization (RHEV) 2.2 and qspice 0.3.0, does not properly restrict the addresses upon which memory-management actions are performed, which allows guest OS users to cause a denial of service (guest OS crash) or possibly gain privileges via unspecified vectors.

sudo: Fails to reset group permissions if runas_default set

sudo 1.6.x before 1.6.9p21, when the runas_default option is used, does not properly set group memberships, which allows local users to gain privileges via a sudo command.

sudo: sudoedit option can possibly allow for arbitrary code execution

sudo 1.6.x before 1.6.9p21 and 1.7.x before 1.7.2p4, when a pseudo-command is enabled, permits a match between the name of the pseudo-command and the name of an executable file in an arbitrary directory, which allows local users to gain privileges via a crafted executable file, as demonstrated by a file named sudoedit in a user's home directory.

kvm: emulator privilege escalation segment selector check

The x86 emulator in KVM 83, when a guest is configured for Symmetric Multiprocessing (SMP), does not properly restrict writing of segment selectors to segment registers, which might allow guest OS users to cause a denial of service (guest OS crash) or gain privileges on the guest OS by leveraging access to a (1) IO port or (2) MMIO region, and replacing an instruction in between emulator entry and instruction fetch.

OpenTTD before 1.0.1 accepts a company password for authentication in response to a request for the server password, which allows remote authenticated users to bypass intended access restrictions or cause a denial of service (daemon crash) by sending a company password packet.

: cups possible arbitrary code execution via suid lppasswd (STR #3482)

The _cupsGetlang function, as used by lppasswd.c in lppasswd in CUPS 1.2.2, 1.3.7, 1.3.9, and 1.4.1, relies on an environment variable to determine the file that provides localized message strings, which allows local users to gain privileges via a file that contains crafted localization data with format string specifiers.

install.php in JCE-Tech PHP Calendars, downloaded 20100121, allows remote attackers to bypass intended access restrictions and modify application settings via a direct request. NOTE: this is only a vulnerability when the administrator does not follow recommendations in the product's installation documentation.

kvm: emulator privilege escalation IOPL/CPL level check

The x86 emulator in KVM 83, when a guest is configured for Symmetric Multiprocessing (SMP), does not use the Current Privilege Level (CPL) and I/O Privilege Level (IOPL) to restrict instruction execution, which allows guest OS users to cause a denial of service (guest OS crash) or gain privileges on the guest OS by leveraging access to a (1) IO port or (2) MMIO region, and replacing an instruction in between emulator entry and instruction fetch, a related issue to CVE-2010-0298.

maildrop: does not drop supplimentary groups when dropping privileges

main.C in maildrop 2.3.0 and earlier, when run by root with the -d option, uses the gid of root for execution of the .mailfilter file in a user's home directory, which allows local users to gain privileges via a crafted file.

kernel: Driver-Core: devtmpfs - set root directory mode to 0755

openSUSE 11.2 installs the devtmpfs root directory with insecure permissions (1777), which allows local users to gain privileges via unspecified vectors.

kvm: emulator privilege escalation

The x86 emulator in KVM 83 does not use the Current Privilege Level (CPL) and I/O Privilege Level (IOPL) in determining the memory access available to CPL3 code, which allows guest OS users to cause a denial of service (guest OS crash) or gain privileges on the guest OS by leveraging access to a (1) IO port or (2) MMIO region, a related issue to CVE-2010-0306.

kernel: untangle the do_mremap()

The Linux kernel before 2.6.32.4 allows local users to gain privileges or cause a denial of service (panic) by calling the (1) mmap or (2) mremap function, aka the "do_mremap() mess" or "mremap/mmap mess."

dokuwiki: multiple vulnerabilities in ACL manager

A typo in the administrator permission check in the ACL Manager plugin (plugins/acl/ajax.php) in DokuWiki before 2009-12-25b allows remote attackers to gain privileges and access closed wikis by editing current ACL statements, as demonstrated in the wild in January 2010.

The Client/Server Run-time Subsystem (CSRSS) in Microsoft Windows 2000 SP4, XP SP2 and SP3, and Server 2003 SP2 does not properly kill processes after a logout, which allows local users to obtain sensitive information or gain privileges via a crafted application that continues to execute throughout the logout of one user and the login session of the next user, aka "CSRSS Local Privilege Elevation Vulnerability."

query.py in the query interface in ViewVC before 1.1.3 does not reject configurations that specify an unsupported authorizer for a root, which might allow remote attackers to bypass intended access restrictions via a query.

The eval_js function in uzbl-core.c in Uzbl before 2010.01.05 exposes the run method of the Uzbl object, which allows remote attackers to execute arbitrary commands via JavaScript code.

The Receive Service in Websense Email Security before 7.1 does not recognize domain extensions in the blacklist, which allows remote attackers to bypass intended access restrictions and send e-mail messages via an SMTP session.

Websense Email Security 7.1 before Hotfix 4 allows remote attackers to bypass the sender-based blacklist by using the 8BITMIME EHLO keyword in the SMTP session.

McAfee Common Management Agent (CMA) 3.5.5 through 3.5.5.588 and 3.6.0 through 3.6.0.608, and McAfee Agent 4.0 before Patch 3, allows remote authenticated users to overwrite arbitrary files by accessing a report-writing ActiveX control COM object.

IBM Tivoli Federated Identity Manager (TFIM) 6.2.0 before 6.2.0.2, when configured as an OpenID provider, does not delete the site information cookie in response to a user's deletion of a relying-party trust entry, which allows user-assisted remote attackers to bypass intended trust restrictions via vectors that trigger absence of the consent-to-authenticate page.
