Google Chrome before 8.0.552.237 and Chrome OS before 8.0.552.344 do not properly perform a cast of an unspecified variable during handling of anchors, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted HTML document.

Multiple buffer overflows in vorbis_dec.c in the Vorbis decoder in FFmpeg, as used in Google Chrome before 8.0.552.237 and Chrome OS before 8.0.552.344, allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly have unspecified other impact via a crafted WebM file, related to buffers for (1) the channel floor and (2) the channel residue.

Google Chrome before 8.0.552.237 and Chrome OS before 8.0.552.344 do not properly handle Cascading Style Sheets (CSS) token sequences in conjunction with cursors, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors that lead to a "stale pointer."

Google Chrome before 8.0.552.224 and Chrome OS before 8.0.552.343 do not properly perform cursor handling, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors that lead to "stale pointers."

The CSSParser::parseFontFaceSrc function in WebCore/css/CSSParser.cpp in WebKit, as used in Google Chrome before 8.0.552.224, Chrome OS before 8.0.552.343, webkitgtk before 1.2.6, and other products does not properly parse Cascading Style Sheets (CSS) token sequences, which allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted local font, related to "Type Confusion."

Double free vulnerability in libxml2 2.7.8 and other versions, as used in Google Chrome before 8.0.552.215 and other products, allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to XPath handling.

Use-after-free vulnerability in Google Chrome before 8.0.552.215 allows remote attackers to cause a denial of service via vectors related to the handling of mouse dragging events.

Use-after-free vulnerability in Google Chrome before 8.0.552.215 allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors involving SVG animations.

libxml2 before 2.7.8, as used in Google Chrome before 7.0.517.44, Apple Safari 5.0.2 and earlier, and other products, reads from invalid memory locations during processing of malformed XPath expressions, which allows context-dependent attackers to cause a denial of service (application crash) via a crafted XML document.

Google Chrome before 7.0.517.44 does not properly perform a cast of an unspecified variable during processing of an SVG use element, which allows remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted SVG document.

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.

Google Chrome before 7.0.517.41 does not properly handle animated GIF images, which allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a crafted image.

The var_export function in PHP 5.2 before 5.2.14 and 5.3 before 5.3.3 flushes the output buffer to the user when certain fatal errors occur, even if display_errors is off, which allows remote attackers to obtain sensitive information by causing the application to exceed limits for memory, execution time, or recursion.

The rendering implementation in Google Chrome before 5.0.375.125 allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via unknown vectors.

OpenOffice.org 2.x and 3.0 before 3.2.1 allows user-assisted remote attackers to bypass Python macro security restrictions and execute arbitrary Python code via a crafted OpenDocument Text (ODT) file that triggers code execution when the macro directory structure is previewed.

The kg_accept_krb5 function in krb5/accept_sec_context.c in the GSS-API library in MIT Kerberos 5 (aka krb5) through 1.7.1 and 1.8 before 1.8.2, as used in kadmind and other applications, does not properly check for invalid GSS-API tokens, which allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) via an AP-REQ message in which the authenticator's checksum field is missing.

The ap_read_request function in server/protocol.c in the Apache HTTP Server 2.2.x before 2.2.15, when a multithreaded MPM is used, does not properly handle headers in subrequests in certain circumstances involving a parent request that has a body, which might allow remote attackers to obtain sensitive information via a crafted request that triggers access to memory locations associated with an earlier request.

The png_decompress_chunk function in pngrutil.c in libpng 1.0.x before 1.0.53, 1.2.x before 1.2.43, and 1.4.x before 1.4.1 does not properly handle compressed ancillary-chunk data that has a disproportionately large uncompressed representation, which allows remote attackers to cause a denial of service (memory and CPU consumption, and application hang) via a crafted PNG file, as demonstrated by use of the deflate compression method on data composed of many occurrences of the same character, related to a "decompression bomb" attack.

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.
