mysqld in MySQL 4.1.x before 4.1.18, 5.0.x before 5.0.19, and 5.1.x before 5.1.6 allows remote authorized users to cause a denial of service (crash) via a NULL second argument to the str_to_date function.

zend_hash_del_key_or_index in zend_hash.c in PHP before 4.4.3 and 5.x before 5.1.3 can cause zend_hash_del to delete the wrong element, which prevents a variable from being unset even when the PHP unset function is called, which might cause the variable's value to be used in security-relevant operations.

Unspecified vulnerability in session.c in PHP before 5.1.3 has unknown impact and attack vectors, related to "certain characters in session names," including special characters that are frequently associated with CRLF injection, SQL injection, cross-site scripting (XSS), and HTTP response splitting vulnerabilities. NOTE: while the nature of the vulnerability is unspecified, it is likely that this is related to a violation of an expectation by PHP applications that the session name is alphanumeric, as implied in the PHP manual for session_name().

The error_log function in basic_functions.c in PHP before 4.4.4 and 5.x before 5.1.5 allows local users to bypass safe mode and open_basedir restrictions via a "php://" or other scheme in the third argument, which disables safe mode.

Mailman before 2.1.9rc1 allows remote attackers to cause a denial of service via unspecified vectors involving "standards-breaking RFC 2231 formatted headers".

OpenSSL 0.9.7 before 0.9.7l, 0.9.8 before 0.9.8d, and earlier versions allows attackers to cause a denial of service (CPU consumption) via parasitic public keys with large (1) "public exponent" or (2) "public modulus" values in X.509 certificates that require extra time to process when using RSA signature verification.

OpenSSL 0.9.7 before 0.9.7l and 0.9.8 before 0.9.8d allows remote attackers to cause a denial of service (infinite loop and memory consumption) via malformed ASN.1 structures that trigger an improperly handled error condition.

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 dvd_read_bca function in the DVD handling code in drivers/cdrom/cdrom.c in Linux kernel 2.2.16, and later versions, assigns the wrong value to a length variable, which allows local users to execute arbitrary code via a crafted USB Storage device that triggers a buffer overflow.

SCTP conntrack (ip_conntrack_proto_sctp.c) in netfilter for Linux kernel 2.6.17 before 2.6.17.3 and 2.6.16 before 2.6.16.23 allows remote attackers to cause a denial of service (crash) via a packet without any chunks, which causes a variable to contain an invalid value that is later used to dereference a pointer.

kdesktop_lock in kdebase before 3.1.3-5.11 for KDE in Red Hat Enterprise Linux (RHEL) 3 does not properly terminate, which can prevent the screensaver from activating or prevent users from manually locking the desktop.

A regression error in the restore_all code path of the 4/4GB split support for non-hugemem Linux kernels on Red Hat Linux Desktop and Enterprise Linux 4 allows local users to cause a denial of service (panic) via unspecified vectors.

artswrapper in aRts, when running setuid root on Linux 2.6.0 or later versions, does not check the return value of the setuid function call, which allows local users to gain root privileges by causing setuid to fail, which prevents artsd from dropping privileges.

PHP remote file inclusion vulnerability in functions/plugin.php in SquirrelMail 1.4.6 and earlier, if register_globals is enabled and magic_quotes_gpc is disabled, allows remote attackers to execute arbitrary PHP code via a URL in the plugins array parameter. NOTE: this issue has been disputed by third parties, who state that Squirrelmail provides prominent warnings to the administrator when register_globals is enabled. Since the varieties of administrator negligence are uncountable, perhaps this type of issue should not be included in CVE. However, the original developer has posted a security advisory, so there might be relevant real-world environments under which this vulnerability is applicable

Double free vulnerability in the getRawDER function for nsIX509Cert in Firefox allows remote attackers to cause a denial of service (hang) and possibly execute arbitrary code via certain Javascript code.

EvalInSandbox in Mozilla Firefox and Thunderbird before 1.5.0.4 allows remote attackers to gain privileges via javascript that calls the valueOf method on objects that were created outside of the sandbox.

HTTP response smuggling vulnerability in Mozilla Firefox and Thunderbird before 1.5.0.4, when used with certain proxy servers, allows remote attackers to cause Firefox to interpret certain responses as if they were responses from two different sites via (1) invalid HTTP response headers with spaces between the header name and the colon, which might not be ignored in some cases, or (2) HTTP 1.1 headers through an HTTP 1.0 proxy, which are ignored by the proxy but processed by the client.

Cross-site scripting (XSS) vulnerability in Mozilla Firefox before 1.5.0.4 allows user-assisted remote attackers to inject arbitrary web script or HTML by tricking a user into (1) performing a "View Image" on a broken image in which the SRC attribute contains a Javascript URL, or (2) selecting "Show only this frame" on a frame whose SRC attribute contains a Javascript URL.

The PLUGINSPAGE functionality in Mozilla Firefox before 1.5.0.4 allows remote user-assisted attackers to execute privileged code by tricking a user into installing missing plugins and selecting the "Manual Install" button, then using nested javascript: URLs. NOTE: the manual install button is used for downloading software from a remote web site, so this issue would not cross privilege boundaries if the user progresses to the point of installing malicious software from the attacker-controlled site.

Mozilla Firefox and Thunderbird before 1.5.0.4 strip the Unicode Byte-order-Mark (BOM) from a UTF-8 page before the page is passed to the parser, which allows remote attackers to conduct cross-site scripting (XSS) attacks via a BOM sequence in the middle of a dangerous tag such as SCRIPT.
