Microsoft Windows Graphics Rendering Engine (GRE) allows remote attackers to corrupt memory and cause a denial of service (crash) via a WMF file containing (1) ExtCreateRegion or (2) ExtEscape function calls with arguments with inconsistent lengths.

The DM Primer (dmprimer.exe) in the DM Deployment Common Component in Computer Associates (CA) BrightStor Mobile Backup r4.0, BrightStor ARCserve Backup for Laptops & Desktops r11.0, r11.1, r11.1 SP1, Unicenter Remote Control 6.0, 6.0 SP1, CA Desktop Protection Suite r2, CA Server Protection Suite r2, and CA Business Protection Suite r2 allows remote attackers to cause a denial of service (CPU consumption or application hang) via a large network packet, which causes a WSAEMESGSIZE error code that is not handled, leading to a thread exit.

The DM Primer in the DM Deployment Common Component in Computer Associates (CA) BrightStor Mobile Backup r4.0, BrightStor ARCserve Backup for Laptops & Desktops r11.0, r11.1, r11.1 SP1, Unicenter Remote Control 6.0, 6.0 SP1, CA Desktop Protection Suite r2, CA Server Protection Suite r2, and CA Business Protection Suite r2 allows remote attackers to cause a denial of service (CPU consumption and log file consumption) via unspecified "unrecognized network messages" that are not properly handled.

OpenSSH on FreeBSD 5.3 and 5.4, when used with OpenPAM, does not properly handle when a forked child process terminates during PAM authentication, which allows remote attackers to cause a denial of service (client connection refusal) by connecting multiple times to the SSH server, waiting for the password prompt, then disconnecting.

NmService.exe in Ipswitch WhatsUp Professional 2006 allows remote attackers to cause a denial of service (CPU consumption) via crafted requests to Login.asp, possibly involving the (1) "In]" and (2) "b;tnLogIn" parameters, or (3) malformed btnLogIn parameters, possibly involving missing "[" (open bracket) or "[" (closing bracket) characters, as demonstrated by "&btnLogIn=[Log&In]=&" or "&b;tnLogIn=[Log&In]=&" in the URL. NOTE: due to the lack of diagnosis by the original researcher, the precise nature of the vulnerability is unclear.

NCP Network Communication Secure Client 8.11 Build 146, and possibly other versions, allows local users to cause a denial of service (CPU consumption) via a large number of arguments to ncprwsnt.exe, possibly due to a buffer overflow.

NCP Network Communication Secure Client 8.11 Build 146, and possibly other versions, allows local users to cause a denial of service (memory usage and cpu utilization) via a flood of arbitrary UDP datagrams to ports 0 to 65000. NOTE: this issue was reported as a buffer overflow, but that term usually does not apply in flooding attacks.

security flaw

A regression fix in Mozilla Firefox 1.0.7 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via the InstallTrigger.install method, which leads to memory corruption.

The substr_compare function in string.c in PHP 5.1.2 allows context-dependent attackers to cause a denial of service (memory access violation) via an out-of-bounds offset argument.

mshtml.dll 6.00.2900.2873, as used in Microsoft Internet Explorer, allows remote attackers to cause a denial of service (crash) via nested OBJECT tags, which trigger invalid pointer dereferences including NULL dereferences. NOTE: the possibility of code execution was originally theorized, but Microsoft has stated that this issue is non-exploitable.

Mozilla Firefox 1.5.0.2, when designMode is enabled, allows remote attackers to cause a denial of service and possibly execute arbitrary code via certain Javascript that is not properly handled by the contentWindow.focus method in an iframe, which causes a reference to a deleted controller context object. NOTE: this was originally claimed to be a buffer overflow in (1) js320.dll and (2) xpcom_core.dll, but the vendor disputes this claim.

The recursor in PowerDNS before 3.0.1 allows remote attackers to cause a denial of service (application crash) via malformed EDNS0 packets.

Nessus before 2.2.8, and 3.x before 3.0.3, allows user-assisted attackers to cause a denial of service (memory consumption) via a NASL script that calls split with an invalid sep parameter. NOTE: a design goal of the NASL language is to facilitate sharing of security tests by guaranteeing that a script "can not do anything nasty." This issue is appropriate for CVE only if Nessus users have an expectation that a split statement will not use excessive memory.

security flaw

The ftdi_sio driver (usb/serial/ftdi_sio.c) in Linux kernel 2.6.x up to 2.6.17, and possibly later versions, allows local users to cause a denial of service (memory consumption) by writing more data to the serial port than the hardware can handle, which causes the data to be queued.

The SMTP service of MailEnable Standard 1.92 and earlier, Professional 2.0 and earlier, and Enterprise 2.0 and earlier before the MESMTPC hotfix, allows remote attackers to cause a denial of service (application crash) via a HELO command with a null byte in the argument, possibly triggering a length inconsistency or a missing argument.

UDF truncating issue

The Universal Disk Format (UDF) filesystem driver in Linux kernel 2.6.17 and earlier allows local users to cause a denial of service (hang and crash) via certain operations involving truncated files, as demonstrated via the dd command.

IBM DB2 Universal Database (UDB) before 8.1 FixPak 13 allows remote authenticated users to cause a denial of service (crash) by (1) sending the first ACCSEC command without an RDBNAM parameter during the CONNECT process, or (2) sending crafted SQLJRA packet, which results in a null dereference.

Microsoft Internet Explorer 6 SP2 6.0.2900.2180 and 6.0.2800.1106, and earlier versions, allows remote attackers to cause a denial of service (crash) and execute arbitrary code via a Javascript BODY onload event that calls the window function, aka "Mismatched Document Object Model Objects Memory Corruption Vulnerability."

security flaw

Fetchmail 6.2.4 and earlier does not properly allocate memory for long lines, which allows remote attackers to cause a denial of service (crash) via a certain email.

security flaw

Zebra 0.93b and earlier, and quagga before 0.95, allows local users to cause a denial of service by sending spoofed messages as other users to the kernel netlink interface.
