Use-after-free vulnerability in kadmin/server/serverstubs.c in kadmind in MIT Kerberos 5 (aka krb5) 1.5 through 1.6.3 allows remote authenticated users to cause a denial of service (daemon crash) via a request from a kadmin client that sends an invalid API version number.
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.

low: Request header information leak CVE-2010-0434
A bug in the handling of headers in subrequests could lead to a reuse of memory. In a multithreaded MPM this could possibly cause an information leak from other requests being handled by a different thread.
Affects: 2.2.0 - 2.2.14
Upstream bug: https://issues.apache.org/bugzilla/showbug.cgi?id=48359
Upstream commits (2.2.x branch): http://svn.apache.org/viewvc?view=revision&revision=917867 http://svn.apache.org/viewvc?view=revision&revision=918427
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.
XMLScanner.java in Apache Xerces2 Java, as used in Sun Java Runtime Environment (JRE) in JDK and JRE 6 before Update 15 and JDK and JRE 5.0 before Update 20, and in other products, allows remote attackers to cause a denial of service (infinite loop and application hang) via malformed XML input, as demonstrated by the Codenomicon XML fuzzing framework.
The decompression implementation in the Imf::hufUncompress function in OpenEXR 1.2.2 and 1.6.1 allows context-dependent attackers to cause a denial of service (application crash) or possibly execute arbitrary code via vectors that trigger a free of an uninitialized pointer.
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.
