(1) services/twitter/twitter-contact-view.c and (2) services/twitter/twitter-item-view.c in libsocialweb before 0.25.20 automatically connect to Twitter when no Twitter account is set, which might allow remote attackers to obtain sensitive information via a man-in-the-middle (MITM) attack.

The server in Microsoft Active Directory on Windows Server 2003 SP2 does not properly handle an update request for a service principal name (SPN), which allows remote attackers to cause a denial of service (authentication downgrade or outage) via a crafted request that triggers name collisions, aka "Active Directory SPN Validation Vulnerability."

The krb5_db2_lockout_audit function in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.8 through 1.8.4, when the db2 (aka Berkeley DB) back end is used, allows remote attackers to cause a denial of service (assertion failure and daemon exit) via unspecified vectors, a different vulnerability than CVE-2011-1528.

Symantec pcAnywhere through 12.5.3, Altiris IT Management Suite pcAnywhere Solution 7.0 (aka 12.5.x) and 7.1 (aka 12.6.x), Altiris Client Management Suite pcAnywhere Solution 7.0 (aka 12.5.x) and 7.1 (aka 12.6.x), and Altiris Deployment Solution Remote pcAnywhere Solution 7.1 (aka 12.5.x and 12.6.x) allow remote attackers to cause a denial of service (application crash or hang) via (1) malformed data from a client, (2) malformed data from a server, or (3) an invalid response.

SBE.dll in the Stream Buffer Engine in Windows Media Player and Windows Media Center in Microsoft Windows XP SP2 and SP3, Windows XP Media Center Edition 2005 SP3, Windows Vista SP1 and SP2, Windows 7 Gold and SP1, and Windows Media Center TV Pack for Windows Vista does not properly parse Digital Video Recording (.dvr-ms) files, which allows remote attackers to execute arbitrary code via a crafted file, aka "DVR-MS Vulnerability."

Mozilla recursive eval call causes confirm dialog to evaluate to true (MFSA 2011-02)

Mozilla Firefox before 3.5.17 and 3.6.x before 3.6.14, and SeaMonkey before 2.0.12, does not properly handle certain recursive eval calls, which makes it easier for remote attackers to force a user to respond positively to a dialog question, as demonstrated by a question about granting privileges.

win32k.sys in the kernel-mode drivers in Microsoft Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista SP1 and SP2, Windows Server 2008 Gold, SP2, and R2, and Windows 7 does not properly validate user-mode input, which allows local users to gain privileges via a crafted application, aka "Win32k Window Class Pointer Confusion Vulnerability."

win32k.sys in the kernel-mode drivers in Microsoft Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista SP1 and SP2, Windows Server 2008 Gold, SP2, and R2, and Windows 7 does not properly validate user-mode input, which allows local users to gain privileges via a crafted application, aka "Win32k Window Class Improper Pointer Validation Vulnerability."

win32k.sys in the kernel-mode drivers in Microsoft Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista SP1 and SP2, Windows Server 2008 Gold, SP2, and R2, and Windows 7 does not properly validate user-mode input, which allows local users to gain privileges via a crafted application, aka "Win32k Memory Corruption Vulnerability."

PyGIT.py in the Trac Git plugin (trac-git) before 0.0.20080710-3+lenny1 and before 0.0.20090320-1 on Debian GNU/Linux, when enabled in Trac, allows remote attackers to execute arbitrary commands via shell metacharacters in a crafted HTTP query that is used to generate a certain git command.

The VPN downloader implementation in the WebLaunch feature in Cisco AnyConnect Secure Mobility Client 2.x before 2.5 MR6 on Windows, and 2.x before 2.5 MR6 and 3.x before 3.0 MR8 on Mac OS X and Linux, does not properly validate binaries that are received by the downloader process, which allows remote attackers to execute arbitrary code via vectors involving (1) ActiveX or (2) Java components, aka Bug ID CSCtw47523.

ocaml: hash table collisions CPU usage DoS (oCERT-2011-003)

OCaml 3.12.1 and earlier computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table.

WebKit, as used in Apple Safari before 5.0.4 and iOS before 4.3, does not properly handle the Attr.style accessor, which allows remote attackers to bypass the Same Origin Policy and inject Cascading Style Sheets (CSS) token sequences via a crafted web site.

kernel: bluetooth HIDP implementation information disclosure

The hidp_setup_hid function in net/bluetooth/hidp/core.c in the Linux kernel before 3.7.6 does not properly copy a certain name field, which allows local users to obtain sensitive information from kernel memory by setting a long name and making an HIDPCONNADD ioctl call.

WebKit, as used in Apple Safari before 5.0.4 and iOS before 4.3, does not properly handle unspecified "cached resources," which allows remote attackers to cause a denial of service (resource unavailability) via a crafted web site that conducts a cache-poisoning attack.

Open redirect vulnerability in admin/index.php in 4images 1.7.10 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a URL in the redirect parameter.

AdaCore Ada Web Services (AWS) before 2.10.2 computes hash values for form parameters without restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service (CPU consumption) by sending many crafted parameters.

The generate-id XPath function in libxslt in Apple iOS 4.3.x before 4.3.2 allows remote attackers to obtain potentially sensitive information about heap memory addresses via a crafted web site. NOTE: this may overlap CVE-2011-1202.

ImageIO in Apple Safari before 5.0.6 on Windows does not properly address re-entrancy issues, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted TIFF file.

Apple Safari before 5.0.6 provides AutoFill information to scripts that execute before HTML form submission, which allows remote attackers to obtain Address Book information via a crafted form, as demonstrated by a form that includes non-visible fields.
