Weekly Vulnerabilities Reports > December 30, 2002 to January 5, 2003

Microsoft Windows Media Player (WMP) 6.3, when installed on Solaris, installs executables with world-writable permissions, which allows local users to delete or modify the executables to gain privileges.

ChaiVM EZloader for HP color LaserJet 4500 and 4550 and HP LaserJet 4100 and 8150 does not properly verify JAR signatures for new services, which allows local users to load unauthorized Chai services.

Sun PC NetLink 1.0 through 1.2 does not properly set the access control list (ACL) for files and directories that use symbolic links and have been restored from backup, which could allow local or remote attackers to bypass intended access restrictions.

SecureClean 3 build 2.0 does not clear Windows alternate data streams that are attached to files on NTFS file systems, which allows attackers to recover sensitive information that was supposed to be deleted.

PGP 6.x and 7.x does not clear Windows alternate data streams that are attached to files on NTFS file systems, which allows attackers to recover sensitive information that was supposed to be deleted.

Eraser 5.3 does not clear Windows alternate data streams that are attached to files on NTFS file systems, which allows attackers to recover sensitive information that was supposed to be deleted.

East-Tec Eraser 2002 does not clear Windows alternate data streams that are attached to files on NTFS file systems, which allows attackers to recover sensitive information that was supposed to be deleted.

BestCrypt BCWipe 1.0.7 and 2.0 through 2.35.1 does not clear Windows alternate data streams that are attached to files on NTFS file systems, which allows attackers to recover sensitive information that was supposed to be deleted.

TeeKai Tracking Online 1.0 uses weak encryption of web usage statistics in data/userlog/log.txt, which allows remote attackers to identify IP's visiting the site by dividing each octet by the MD5 hash of '20'.

The Network Attached Storage (NAS) Administration Web Page for Iomega NAS A300U transmits passwords in cleartext, which allows remote attackers to sniff the administrative password.

SkyStream EMR5000 1.16 through 1.18 does not drop packets or disable the Ethernet interface when the buffers are full, which allows remote attackers to cause a denial of service (null pointer exception and kernel panic) via a large number of packets.

Click2Learn Ingenium Learning Management System 5.1 and 6.1 uses weak encryption for passwords (reversible algorithm), which allows attackers to obtain passwords.

Microsoft SQL Server 6.0 through 2000, with SQL Authentication enabled, uses weak password encryption (XOR), which allows remote attackers to sniff and decrypt the password.

mod_cgi in Apache 2.0.39 and 2.0.40 allows local users and possibly remote attackers to cause a denial of service (hang and memory consumption) by causing a CGI script to send a large amount of data to stderr, which results in a read/write deadlock between httpd and the CGI script.

D-Link DWL-900AP+ Access Point 2.1 and 2.2 allows remote attackers to access the TFTP server without authentication and read the config.img file, which contains sensitive information such as the administrative password, the WEP encryption keys, and network configuration information.

phpRank 1.8 stores the administrative password in plaintext on the server and in the "ap" cookie, which allows remote attackers to retrieve the administrative password.

Off-by-one error in the CodeBrws.asp sample script in Microsoft IIS 5.0 allows remote attackers to view the source code for files with extensions containing with one additional character after .html, .htm, .asp, or .inc, such as .aspx files.

Off-by-one error in alterMIME 0.1.10 and 0.1.11 allows remote attackers to cause a denial of service (crash) via an x-header that causes snprintf overwrite the FFGET_FILE variable with a (null) byte.

Cisco IOS software 11.3 through 12.2 running on Cisco uBR7200 and uBR7100 series Universal Broadband Routers allows remote attackers to modify Data Over Cable Service Interface Specification (DOCSIS) settings via a DOCSIS file without a Message Integrity Check (MIC) signature, which is approved by the router.

Electronic Code Book (ECB) mode in VTun 2.0 through 2.5 uses a weak encryption algorithm that produces the same ciphertext from the same plaintext blocks, which could allow remote attackers to gain sensitive information.

PostgreSQL uses the username for a salt when generating passwords, which makes it easier for remote attackers to guess passwords via a brute force attack.

Sharp Zaurus PDA SL-5000D and SL-5500 uses a salt of "A0" to encrypt the screen-locking password as stored in the Security.conf file, which makes it easier for local users to guess the password via brute force methods.

Videsh Sanchar Nigam Limited (VSNL) Integrated Dialer Software 1.2.000, when the "Save Password" option is used, stores the password with a weak encryption scheme (one-to-one mapping) in a registry key, which allows local users to obtain and decrypt the password.

tip on multiple BSD-based operating systems allows local users to cause a denial of service (execution prevention) by using flock() to lock the /var/log/acculog file.

dump 0.4 b10 through b29 allows local users to cause a denial of service (execution prevention) by using flock() to lock the /etc/dumpdates file.

Alt-N Technologies Mdaemon 5.0 through 5.0.6 uses a weak encryption algorithm to store user passwords, which allows local users to crack passwords.

The Standard security setting for Mandrake-Security package (msec) in Mandrake 8.2 installs home directories with world-readable permissions, which could allow local users to read other user's files.

Microsoft Outlook plug-in PGP version 7.0, 7.0.3, and 7.0.4 silently saves a decrypted copy of a message to hard disk when "Automatically decrypt/verify when opening messages" option is checked, "Always use Secure Viewer when decrypting" option is not checked, and the user replies to an encrypted message.

NewsReactor 1.0 uses a weak encryption scheme, which could allow local users to decrypt the passwords and gain access to other users' newsgroup accounts.

Heysoft EventSave 5.1 and 5.2 and Heysoft EventSave+ 5.1 and 5.2 does not check whether the log file can be written to, which allows attackers to prevent events from being recorded by opening the log file using an application such as Microsoft's Event Viewer.
