Security Vulnerabilities, CVEs, Published In 2003 (Denial of service) CVSS score >= 8

libxml2, possibly before 2.5.0, does not properly detect recursion during entity expansion, which allows context-dependent attackers to cause a denial of service (memory and CPU consumption) via a crafted XML document containing a large number of nested entity references, aka the "billion laughs attack."

Unspecified vulnerability in the non-SSL web agent in various HP Management Agent products allows local users or remote attackers to gain privileges or cause a denial of service via unknown attack vectors.

Buffer overflow in IMAP service in MDaemon 6.7.5 and earlier allows remote authenticated users to cause a denial of service (crash) and execute arbitrary code via a CREATE command with a long mailbox name.

Epic Games Unreal Engine 226f through 436 allows remote attackers to cause a denial of service (CPU consumption or crash) and possibly execute arbitrary code via (1) a packet with a negative size value, which is treated as a large positive number during memory allocation, or (2) a negative size value in a package file.

Cisco IOS 12.0 through 12.2, when IP routing is disabled, accepts false ICMP redirect messages, which allows remote attackers to cause a denial of service (network routing modification).

Buffer overflow in KaZaA Media Desktop 2.0 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a response to the ad server.

Buffer overflow in Gupta SQLBase 8.1.0 allows remote attackers to cause a denial of service and possibly execute arbitrary code via a long EXECUTE command.

Aprelium Technologies Abyss Web Server 1.1.2, and possibly other versions before 1.1.4, allows remote attackers to cause a denial of service (crash) via an HTTP GET message with empty (1) Connection or (2) Range fields.

Stack-based buffer overflow in eZnet.exe, as used in eZ (a) eZphotoshare, (b) eZmeeting, (c) eZnetwork, and (d) eZshare allows remote attackers to cause a denial of service (crash) or execute arbitrary code, as demonstrated via (1) a long GET request and (2) a long operation or autologin parameter to SwEzModule.dll.

Multiple buffer overflows in Winamp 3.0 allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a .b4s file containing (1) a long playlist name or (2) a long path in a file: argument to the Playstring parameter.

Multiple integer overflows in the 32bit emulation for AMD64 architectures in Linux 2.4 kernel before 2.4.21 allows attackers to cause a denial of service or gain root privileges via unspecified vectors that trigger copy_from_user function calls with improper length arguments.

Double free vulnerability in OpenSSL 0.9.7 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via an SSL client certificate with a certain invalid ASN.1 encoding.

Apple QuickTime / Darwin Streaming Server before 4.1.3g allows remote attackers to cause a denial of service (crash) via a .. (dot dot) sequence followed by an MS-DOS device name (e.g. AUX) in a request to HTTP port 1220, a different vulnerability than CVE-2003-0421.

Format string vulnerability in (1) Bahamut IRCd 1.4.35 and earlier, and other IRC daemons based on Bahamut including (2) digatech 1.2.1, (3) methane 0.1.1, (4) AndromedeIRCd 1.2.3-Release, and (5) ircd-RU, when running in debug mode, allows remote attackers to cause a denial of service and possibly execute arbitrary code via a request containing format strings.

Apple QuickTime / Darwin Streaming Server before 4.1.3f allows remote attackers to cause a denial of service (crash) via an MS-DOS device name (e.g. AUX) in a request to HTTP port 1220, a different vulnerability than CVE-2003-0502.

Buffer overflow in BRS WebWeaver 1.04 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long HTTP (1) POST or (2) HEAD request.

Multiple off-by-one vulnerabilities in Ethereal 0.9.11 and earlier allow remote attackers to cause a denial of service and possibly execute arbitrary code via the (1) AIM, (2) GIOP Gryphon, (3) OSPF, (4) PPTP, (5) Quake, (6) Quake2, (7) Quake3, (8) Rsync, (9) SMB, (10) SMPP, and (11) TSP dissectors, which do not properly use the tvb_get_nstringz and tvb_get_nstringz0 functions.

Off-by-one error in the xlog function of mountd in the Linux NFS utils package (nfs-utils) before 1.0.4 allows remote attackers to cause a denial of service and possibly execute arbitrary code via certain RPC requests to mountd that do not contain newlines.

Multiple buffer overflows in Samba before 2.2.8a may allow remote attackers to execute arbitrary code or cause a denial of service, as discovered by the Samba team and a different vulnerability than CVE-2003-0201.

Multiple buffer overflows in Lotus Domino Web Server before 6.0.1 allow remote attackers to cause a denial of service or execute arbitrary code via (1) the s_ViewName option in the PresetFields parameter for iNotes, (2) the Foldername option in the PresetFields parameter for iNotes, or (3) a long Host header, which is inserted into a long Location header and used during a redirect operation.

The prescan() function in the address parser (parseaddr.c) in Sendmail before 8.12.9 does not properly handle certain conversions from char and int types, which can cause a length check to be disabled when Sendmail misinterprets an input value as a special "NOCHAR" control value, allowing attackers to cause a denial of service and possibly execute arbitrary code via a buffer overflow attack using messages, a different vulnerability than CVE-2002-1337.

Format string vulnerability in the CLI interface for WatchGuard Firebox Vclass 3.2 and earlier, and RSSA Appliance 3.0.2, allows remote attackers to cause a denial of service and possibly execute arbitrary code via format string specifiers in the password parameter.
