nsrd.exe in EMC Legato NetWorker 7.1.x before 7.1.4 and 7.2.x before 7.2.1.Build.314, and other products such as Sun Solstice Backup (SBU) 6.0 and 6.1 and StorEdge Enterprise Backup Software (EBS) 7.1 through 7.2L, allows remote attackers to cause a denial of service (nsrd service crash) via a malformed RPC request to RPC program number 390109, which triggers a null dereference.

Unspecified vulnerability in the "privilege management" feature of Sun Solaris 10 allows local users to cause a denial of service (panic) via unknown vectors that trigger a null dereference in the secpolicy_fs_common function.

Microsoft Internet Explorer 6.0 on Windows NT 4.0 SP6a, Windows 2000 SP4, Windows XP SP1, Windows XP SP2, and Windows Server 2003 SP1 allows remote attackers to cause a denial of service (client crash) via a certain combination of a malformed HTML file and a CSS file that triggers a null dereference, probably related to rendering of a DIV element that contains a malformed IMG tag, as demonstrated by IEcrash.htm and IEcrash.rar.

The Outlook Express Address Book control, when using Internet Explorer 6, allows remote attackers to cause a denial of service (NULL dereference and browser crash) by creating the OutlookExpress.AddressBook COM object, which is not intended for use within Internet Explorer.

The (1) to_char and (2) to_date function in IBM DB2 8.1 allows local users to cause a denial of service (application crash) via an empty string in the second parameter, which causes a null pointer dereference.

freeFTPd 1.0.10 allows remote authenticated users to cause a denial of service (null dereference and crash) via a PORT command with missing arguments.

The nfattr_to_tcp function in ip_conntrack_proto_tcp.c in ctnetlink in Linux kernel 2.6.14 up to 2.6.14.3 allows attackers to cause a denial of service (kernel oops) via an update message without private protocol information, which triggers a null dereference.

ip_conntrack_proto_icmp.c in ctnetlink in Linux kernel 2.6.14 up to 2.6.14.3 allows attackers to cause a denial of service (kernel oops) via a message without ICMP ID (ICMP_ID) information, which leads to a null dereference.

The Internet Key Exchange version 1 (IKEv1) implementation (isakmp_agg.c) in racoon in ipsec-tools before 0.6.3, when running in aggressive mode, allows remote attackers to cause a denial of service (null dereference and crash) via crafted IKE packets, as demonstrated by the PROTOS ISAKMP Test Suite for IKEv1.

Apple QuickTime Player before 7.0.3 allows user-assisted attackers to cause a denial of service (crash) via a crafted file with a missing movie attribute, which leads to a null dereference.

libungif library before 4.1.0 allows attackers to cause a denial of service via a crafted GIF file that triggers a null dereference.

FlatFrag 0.3 and earlier allows remote attackers to cause a denial of service (crash) by sending an NT_CONN_OK command from a client that is not connected, which triggers a null dereference.

OpenVPN 2.x before 2.0.4, when running in TCP mode, allows remote attackers to cause a denial of service (segmentation fault) by forcing the accept function call to return an error status, which leads to a null dereference in an exception handler.
