Weekly Vulnerabilities Reports > November 1 to 7, 2004

RealNetworks Helix Universal Server 9.0.2 for Linux and 9.0.3 for Windows allows remote attackers to cause a denial of service (CPU and memory exhaustion) via a POST request with a Content-Length header set to -1.

The Microsoft .NET forms authentication capability for ASP.NET allows remote attackers to bypass authentication for .aspx files in restricted directories via a request containing a (1) "\" (backslash) or (2) "%5C" (encoded backslash), aka "Path Validation Vulnerability."

Unknown vulnerability in Microsoft Excel 2000, 2002, 2001 for Mac, and v.X for Mac allows remote attackers to execute arbitrary code via a malicious file containing certain parameters that are not properly validated.

MySQL 3.x before 3.23.59, 4.x before 4.0.19, 4.1.x before 4.1.2, and 5.x before 5.0.1, checks the CREATE/INSERT rights of the original table instead of the target table in an ALTER TABLE RENAME operation, which could allow attackers to conduct unauthorized activities.

The unix_clean_name function in Samba 2.2.x through 2.2.11, and 3.0.x before 3.0.2a, trims certain directory names down to absolute paths, which could allow remote attackers to bypass the specified share restrictions and read, write, or list arbitrary files via "/.////" style sequences in pathnames.

The RPC Runtime Library for Microsoft Windows NT 4.0 allows remote attackers to read active memory or cause a denial of service (system crash) via a malicious message, possibly related to improper length values.

Sophos Small Business Suite 1.00 on Windows does not properly handle files whose names contain reserved MS-DOS device names such as (1) LPT1, (2) COM1, (3) AUX, (4) CON, or (5) PRN, which can allow malicious code to bypass detection when it is installed, copied, or executed.

Network Dynamic Data Exchange (NetDDE) services for Microsoft Windows 98, Windows NT 4.0, Windows 2000, Windows XP, and Windows Server 2003 allows attackers to remotely execute arbitrary code or locally gain privileges via a malicious message or application that involves an "unchecked buffer," possibly a buffer overflow.

The Virtual DOS Machine (VDM) subsystem of Microsoft Windows NT 4.0, Windows 2000, Windows XP, and Windows Server 2003 allows local users to access kernel memory and gain privileges via a malicious program that modified some system structures in a way that is not properly validated by privileged operating system functions.

Internet Explorer 5.01, 5.5, and 6 does not properly cache SSL content, which allows remote attackers to obtain information or spoof content via a web site with the same host name as the target web site, whose content is cached and reused when the user visits the target web site.

php_variables.c in PHP before 5.0.2 allows remote attackers to read sensitive memory contents via (1) GET, (2) POST, or (3) COOKIE GPC variables that end in an open bracket character, which causes PHP to calculate an incorrect string length.

FreeRADIUS before 1.0.1 allows remote attackers to cause a denial of service (server crash) by sending an Ascend-Send-Secret attribute without the required leading packet.

Symantec Norton AntiVirus 2004, and earlier versions, allows a virus or other malicious code to avoid detection or cause a denial of service (application crash) using a filename containing an MS-DOS device name.

telnetd for netkit 0.17 and earlier, and possibly other versions, on Debian GNU/Linux allows remote attackers to cause a denial of service (free of an invalid pointer), a different vulnerability than CVE-2001-0554.

Internet Explorer 6 on Double Byte Character Set (DBCS) systems allows remote attackers to alter displayed address bars and spoof web pages via a URL containing special characters, facilitating phishing attacks, aka the "Address Bar Spoofing on Double Byte Character Set Systems Vulnerability."

Internet Explorer 5.5 and 6 does not properly handle plug-in navigation, which allows remote attackers to alter displayed address bars and thereby spoof web pages, facilitating phishing attacks, aka the "Plug-in Navigation Address Bar Spoofing Vulnerability."

The (1) ntlm_fetch_string and (2) ntlm_get_string functions in Squid 2.5.6 and earlier, with NTLM authentication enabled, allow remote attackers to cause a denial of service (application crash) via an NTLMSSP packet that causes a negative value to be passed to memcpy.

The WebDAV Message Handler for Internet Information Services (IIS) 5.0, 5.1, and 6.0 allows remote attackers to cause a denial of service (memory and CPU exhaustion, application crash) via a PROPFIND request with an XML message containing XML elements with a large number of attributes.

Apple Safari 1.0 through 1.2.3 allows remote attackers to spoof the URL displayed in the status bar via TABLE tags.

Vulnerability in tif_dirread.c for libtiff allows remote attackers to cause a denial of service (application crash) via a TIFF image that causes a divide-by-zero error when the number of row bytes is zero, a different vulnerability than CVE-2005-2452.

rfc1867.c in PHP before 5.0.2 allows local users to upload files to arbitrary locations via a PHP script with a certain MIME header that causes the "$_FILES" array to be modified.

The ctstrtcasd program in RSCT 2.3.0.0 and earlier on IBM AIX 5.2 and 5.3 does not properly drop privileges before executing the -f option, which allows local users to modify or create arbitrary files.

The kernel for Microsoft Windows Server 2003 does not reset certain values in CPU data structures, which allows local users to cause a denial of service (system crash) via a malicious program.

"Shatter" style vulnerability in the Window Management application programming interface (API) for Microsoft Windows 98, Windows NT 4.0, Windows 2000, Windows XP, and Windows Server 2003 allows local users to gain privileges by using certain API functions to change properties of privileged programs using the SetWindowLong and SetWIndowLongPtr API functions.
