Weekly Vulnerabilities Reports > December 9 to 15, 2002

TightVNC before 1.2.6 generates the same challenge string for multiple connections, which allows remote attackers to bypass VNC authentication by sniffing the challenge and response of other users.

Multiple buffer overflows in RealOne and RealPlayer allow remote attackers to execute arbitrary code via (1) a Synchronized Multimedia Integration Language (SMIL) file with a long parameter, (2) a long long filename in a rtsp:// request, e.g.

Buffer overflow in Dispatch() routine for XFS font server (fs.auto) on Solaris 2.5.1 through 9 allows remote attackers to cause a denial of service (crash) or execute arbitrary code via a certain XFS query.

Internet Explorer 5.5 and 6.0 allows remote attackers to bypass the cross-domain security model and access information on the local system or in other domains, and possibly execute code, via cached methods and objects, aka "Cross Domain Verification via Cached Methods."

Microsoft Windows 98 and Windows NT 4.0 do not properly verify the Basic Constraints of digital certificates, allowing remote attackers to execute code, aka "New Variant of Certificate Validation Flaw Could Enable Identity Spoofing" (CAN-2002-0862).

Cross-site scripting (XSS) vulnerability in BizDesign ImageFolio 3.01 and earlier allows remote attackers to execute arbitrary web script as other users via (1) the direct parameter in imageFolio.cgi, or (2) nph-build.cgi.

Cross-site scripting vulnerability (XSS) in Internet Explorer 5.01 through 6.0 allows remote attackers to read and execute files on the local system via web pages using the <frame> or <iframe> element and javascript, aka "Frames Cross Site Scripting," as demonstrated using the PrivacyPolicy.dlg resource.

Internet Explorer 5.01 through 6.0 allows remote attackers to identify the path to the Temporary Internet Files folder and obtain user information such as cookies via certain uses of the OBJECT tag, which are not subjected to the proper security checks, aka "Temporary Internet Files folders Name Reading."

Rational ClearCase 4.1, 2002.05, and possibly other versions allows remote attackers to cause a denial of service (crash) via certain packets to port 371, e.g.

Pine 4.44 and earlier allows remote attackers to cause a denial of service (core dump and failed restart) via an email message with a From header that contains a large number of quotation marks (").

Mac OS X 10.2.2 allows remote attackers to cause a denial of service by accessing the CUPS Printing Web Administration utility, aka "CUPS Printing Web Administration is Remotely Accessible."

Internet Explorer 5.01 through 6.0 does not properly perform security checks on certain encoded characters within a URL, which allows a remote attacker to steal potentially sensitive information from a user by redirecting the user to another site that has that information, aka "Encoded Characters Information Disclosure."

Internet Explorer 5.01 through 6.0 does not properly check certain parameters of a PNG file when opening it, which allows remote attackers to cause a denial of service (crash) by triggering a heap-based buffer overflow using invalid length codes during decompression, aka "Malformed PNG Image File Failure."

Unknown vulnerability in NetInfo Manager application in Mac OS X 10.2.2 allows local users to access restricted parts of a filesystem.

Mac OS X 10.2.2 allows local users to gain privileges via a mounted ISO 9600 CD, aka "User Privilege Elevation via Mounting an ISO 9600 CD."

Mac OS X 10.2.2 allows local users to gain privileges by mounting a disk image file that was created on another system, aka "Local User Privilege Elevation via Disk Image File."

The Linux kernel 2.4.20 and earlier, and 2.5.x, when running on x86 systems, allows local users to cause a denial of service (hang) via the emulation mode, which does not properly clear TF and NT EFLAGs.

Mac OS X 10.2.2 allows local users to read files that only allow write access via the map_fd() Mach system call.
