ipp.c in cupsd in CUPS 1.4.4 and earlier does not properly allocate memory for attribute values with invalid string data types, which allows remote attackers to cause a denial of service (use-after-free and application crash) or possibly execute arbitrary code via a crafted IPP request.

Mozilla Firefox 3.5.x through 3.5.14 and 3.6.x through 3.6.11, Thunderbird 3.1.6 before 3.1.6 and 3.0.x before 3.0.10, and SeaMonkey 2.x before 2.0.10, when JavaScript is enabled, allows remote attackers to execute arbitrary code via vectors related to nsCSSFrameConstructor::ContentAppended, the appendChild method, incorrect index tracking, and the creation of multiple frames, which triggers memory corruption, as exploited in the wild in October 2010 by the Belmoo malware.

Google Chrome before 7.0.517.41 does not properly handle element maps, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to "stale elements."

The sandbox implementation in Google Chrome before 7.0.517.41 on Linux does not properly constrain worker processes, which might allow remote attackers to bypass intended access restrictions via unspecified vectors.

Google Chrome before 7.0.517.41 on Linux does not properly set the PATH environment variable, which has unspecified impact and attack vectors.

The SPDY protocol implementation in Google Chrome before 6.0.472.62 does not properly manage buffers, which might allow remote attackers to execute arbitrary code via unspecified vectors.

The slap_modrdn2mods function in modrdn.c in OpenLDAP 2.4.22 does not check the return value of a call to the smr_normalize function, which allows remote attackers to cause a denial of service (segmentation fault) and possibly execute arbitrary code via a modrdn call with an RDN string containing invalid UTF-8 sequences, which triggers a free of an invalid, uninitialized pointer in the slap_mods_free function, as demonstrated using the Codenomicon LDAPv3 test suite.

Windows Shell in Microsoft Windows XP SP3, Server 2003 SP2, Vista SP1 and SP2, Server 2008 SP2 and R2, and Windows 7 allows local users or remote attackers to execute arbitrary code via a crafted (1) .LNK or (2) .PIF shortcut file, which is not properly handled during icon display in Windows Explorer, as demonstrated in the wild in July 2010, and originally reported for malware that leverages CVE-2010-2772 in Siemens WinCC SCADA systems.

Buffer overflow in pngpread.c in libpng before 1.2.44 and 1.4.x before 1.4.3, as used in progressive applications, might allow remote attackers to execute arbitrary code via a PNG image that triggers an additional data row.

Linksys WAP54Gv3 firmware 3.04.03 and earlier uses a hard-coded username (Gemtek) and password (gemtekswd) for a debug interface for certain web pages, which allows remote attackers to execute arbitrary commands via the (1) data1, (2) data2, or (3) data3 parameters to (a) Debug_command_page.asp and (b) debug.cgi.

Adobe Flash Player before 9.0.277.0 and 10.x before 10.1.53.64; Adobe AIR before 2.0.2.12610; and Adobe Reader and Acrobat 9.x before 9.3.3, and 8.x before 8.2.3 on Windows and Mac OS X, allow remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via crafted SWF content, related to authplay.dll and the ActionScript Virtual Machine 2 (AVM2) newfunction instruction, as exploited in the wild in June 2010.

The dechunk filter in PHP 5.3 through 5.3.2, when decoding an HTTP chunked encoding stream, allows context-dependent attackers to cause a denial of service (crash) and possibly trigger memory corruption via a negative chunk size, which bypasses a signed comparison, related to an integer overflow in the chunk size decoder.

Unspecified vulnerability in the Java Runtime Environment component in Oracle Java SE and Java for Business 6 Update 18, 5.0 Update 23, and 1.4.2_25 allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors. NOTE: the previous information was obtained from the March 2010 CPU. Oracle has not commented on claims from a reliable researcher that this is related to improper checks when executing privileged methods in the Java Runtime Environment (JRE), which

Use-after-free vulnerability in the Peer Objects component (aka iepeers.dll) in Microsoft Internet Explorer 6, 6 SP1, and 7 allows remote attackers to execute arbitrary code via vectors involving access to an invalid pointer after the deletion of an object, as exploited in the wild in March 2010, aka "Uninitialized Memory Corruption Vulnerability."

Multiple directory traversal vulnerabilities in Lintian 1.23.x through 1.23.28, 1.24.x through 1.24.2.1, and 2.x before 2.3.2 allow remote attackers to overwrite arbitrary files or obtain sensitive information via vectors involving (1) control field names, (2) control field values, and (3) control files of patch systems.

The kernel in Microsoft Windows NT 3.1 through Windows 7, including Windows 2000 SP4, Windows XP SP2 and SP3, Windows Server 2003 SP2, Windows Vista Gold, SP1, and SP2, and Windows Server 2008 Gold and SP2, when access to 16-bit applications is enabled on a 32-bit x86 platform, does not properly validate certain BIOS calls, which allows local users to gain privileges by crafting a VDM_TIB data structure in the Thread Environment Block (TEB), and then calling the NtVdmControl function to start th

Use-after-free vulnerability in Microsoft Internet Explorer 6, 6 SP1, 7, and 8 on Windows 2000 SP4; Windows XP SP2 and SP3; Windows Server 2003 SP2; Windows Vista Gold, SP1, and SP2; Windows Server 2008 Gold, SP2, and R2; and Windows 7 allows remote attackers to execute arbitrary code by accessing a pointer associated with a deleted object, related to incorrectly initialized memory and improper handling of objects in memory, as exploited in the wild in December 2009 and January 2010 during Opera

thttpd 2.25b0 writes data to a log file without sanitizing non-printable characters, which might allow remote attackers to modify a window's title, or possibly execute arbitrary commands or overwrite files, via an HTTP request containing an escape sequence for a terminal emulator.
