MySQL before 5.1.48 allows remote authenticated users with alter database privileges to cause a denial of service (server crash and database loss) via an ALTER DATABASE command with a #mysql50# string followed by a . (dot), .. (dot dot), ../ (dot dot slash) or similar sequence, and an UPGRADE DATA DIRECTORY NAME command, which causes MySQL to move certain directories to the server data directory.

pam_motd (aka the MOTD module) in libpam-modules before 1.1.0-2ubuntu1.1 in PAM on Ubuntu 9.10 and libpam-modules before 1.1.1-2ubuntu5 in PAM on Ubuntu 10.04 LTS allows local users to change the ownership of arbitrary files via a symlink attack on .cache in a user's home directory, related to "user file stamps" and the motd.legal-notice file.

Google Chrome before 5.0.375.99 allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via an invalid SVG document.

The implementation of the Unicode Bidirectional Algorithm (aka Bidi algorithm or UBA) in Google Chrome before 5.0.375.99 allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via unknown vectors.

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.

Memory leak in pngrutil.c in libpng before 1.2.44, and 1.4.x before 1.4.3, allows remote attackers to cause a denial of service (memory consumption and application crash) via a PNG image containing malformed Physical Scale (aka sCAL) chunks.

Stack-based buffer overflow in the TIFFFetchSubjectDistance function in tif_dirread.c in LibTIFF before 3.9.4 allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a long EXIF SubjectDistance field in a TIFF file.

WebKit in Apple Safari before 5.0 on Mac OS X 10.5 through 10.6 and Windows, Apple Safari before 4.1 on Mac OS X 10.4, and Google Chrome before 5.0.375.70 does not properly handle a transformation of a text node that has the IBM1147 character set, which allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted HTML document containing a BR element, related to a "type checking issue."

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.
