The pngdecompresschunk 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.

The ipevictor function in ipfragment.c in libnids before 1.24, as used in dsniff and possibly other products, allows remote attackers to cause a denial of service (NULL pointer dereference and crash) via crafted fragmented packets.

The kgacceptkrb5 function in krb5/acceptseccontext.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.

MySQL-GUI-tools (mysql-administrator) leaks passwords into process list after with launch of mysql text console

mysql-gui-tools (mysql-query-browser and mysql-admin) before 5.0r14+openSUSE-2.3 exposes the password of a user connected to the MySQL server in clear text form via the list of running processes.

It is possible to cause a DoS condition by causing the server to crash in alien-arena 7.33 by supplying various invalid parameters to the download command.
