Security Vulnerabilities Published In 2001 (Denial of service)

The timed program (in.timed) in UnixWare 7 and OpenUnix 8.0.0 does not properly terminate certain strings with a null, which allows remote attackers to cause a denial of service.

Apple Personal Web Sharing (PWS) 1.1, 1.5, and 1.5.5, when Web Sharing authentication is enabled, allows remote attackers to cause a denial of service via a long password, possibly due to a buffer overflow.

setrlimit in HP-UX 10.01, 10.10, 10.24, 10.20, 11.00, 11.04 and 11.11 does not properly enforce core file size on processes after setuid or setgid privileges are dropped, which could allow local users to cause a denial of service by exhausting available disk space.

Win32k.sys (aka Graphics Device Interface (GDI)) in Windows 2000 and XP allows local users to cause a denial of service (system crash) by calling the ShowWindow function after receiving a WM_NCCREATE message.

The uipc system calls (uipc_syscalls.c) in OpenBSD 2.9 and 3.0 provide user mode return instead of versus rval kernel mode values to the fdrelease function, which allows local users to cause a denial of service and trigger a null dereference.

Unknown vulnerability in IP defragmenter (frag2) in Snort before 1.8.3 allows attackers to cause a denial of service (crash).

IBM AIX 430 does not properly unlock IPPMTU_LOCK, which allows remote attackers to cause a denial of service (hang) via Path Maximum Transmit Unit (PMTU) IP packets.

ssdpsrv.exe in Windows ME allows remote attackers to cause a denial of service by sending multiple newlines in a Simple Service Discovery Protocol (SSDP) message. NOTE: multiple replies to the original post state that the problem could not be reproduced.

IPRoute 0.973, 0.974 and 1.18 allows remote attackers to cause a denial of service via fragmented IP packets that split the TCP header.

Stack consumption vulnerability in Internet Explorer The JavaScript settimeout function in Internet Explorer allows remote attackers to cause a denial of service (crash) via the JavaScript settimeout function. NOTE: the vendor could not reproduce the problem.

** DISPUTED * Microsoft Internet Security and Acceleration (ISA) Server 2000 allows remote attackers to cause a denial of service via a flood of fragmented UDP packets. NOTE: the vendor disputes this issue, saying that it requires high bandwidth to exploit, and the server does not experience any instability. Therefore this "laws of physics" issue might not be included in CVE.

Buffer overflow in Claris Emailer 2.0v2 allows remote attackers to cause a denial of service and possibly execute arbitrary code via an email attachment with a long filename.

RunAs (runas.exe) in Windows 2000 only creates one session instance at a time, which allows local users to cause a denial of service (RunAs hang) by creating a named pipe session with the authentication server without any request for service. NOTE: the vendor disputes this vulnerability, however the vendor also presents a scenario in which other users could be affected if running on a Terminal Server. Therefore this is a vulnerability.

The glob functionality in ProFTPD 1.2.1, and possibly other versions allows remote attackers to cause a denial of service (CPU and memory consumption) via commands with large numbers of wildcard and other special characters, as demonstrated using an ls command with multiple (1) "*/..", (2) "*/.*", or (3) ".*./*?/" sequences in the argument.

Off-by-one buffer overflow in Basic Authentication in Acme Labs thttpd 1.95 through 2.20 allows remote attackers to cause a denial of service and possibly execute arbitrary code.

Opera 5.11 allows remote attackers to cause a denial of service (CPU consumption and memory leak) via a web page with a large number of images.

Mozilla 0.9.6 allows remote attackers to cause a denial of service (CPU consumption and memory leak) via a web page with a large number of images.

Microsoft Internet Explorer 6 allows remote attackers to cause a denial of service (CPU consumption and memory leak) via a web page with a large number of images.

Microsoft Internet Explorer 5.0 through 6.0 allows attackers to cause a denial of service (browser crash) via a crafted FTP URL such as "/.#./".

Buffer overflow in the text editor functionality in HP-UX 10.01 through 11.04 on HP9000 Series 700 and Series 800 allows local users to cause a denial of service ("system availability") via text editors such as (1) e, (2) ex, (3) vi, (4) edit, (5) view, and (6) vedit.

Handspring Visor 1.0 and 1.0.1 with the VisorPhone Springboard module installed allows remote attackers to cause a denial of service (PalmOS crash and VisorPhone database corruption) by sending a large or crafted SMS image.

inetd in Compaq Tru64 UNIX 5.1 allows attackers to cause a denial of service (network connection loss) by causing one of the services handled by inetd to core dump during startup, which causes inetd to stop accepting connections to all of its services.

Buffer overflow in mcedit in Midnight Commander 4.5.1 allows local users to cause a denial of service (segmentation fault) and possibly execute arbitrary code via a crafted text file.

AOL Instant Messenger (AIM) 4.7 and earlier allows remote attackers to cause a denial of service (application crash) via a large number of different fonts followed by an HTML HR tag.

AOL Instant Messenger (AIM) 4.7.2480 and earlier allows remote attackers to cause a denial of service (application crash) via an instant message that contains a large amount of "<!--" HTML comments.
