Weekly Vulnerabilities Reports > February 17 to 23, 2003

The showHelp() function in Microsoft Internet Explorer 5.01, 5.5, and 6.0 supports certain types of pluggable protocols that allow remote attackers to bypass the cross-domain security model and execute arbitrary code, aka "Improper Cross Domain Security Validation with ShowHelp functionality."

Microsoft Internet Explorer 5.5 and 6.0 allows remote attackers to bypass the cross-domain security model to run malicious script or arbitrary programs via dialog boxes, aka "Improper Cross Domain Security Validation with dialog box."

Integer signedness error in the myFseek function of samplein.c for Blade encoder (BladeEnc) 0.94.2 and earlier allows remote attackers to execute arbitrary code via a negative offset value following a "fmt" wave chunk.

Format string vulnerabilities in the logging routines for MIT Kerberos V5 Key Distribution Center (KDC) before 1.2.5 allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via format string specifiers in Kerberos principal names.

Unknown vulnerability in the chk_trans.c of the libkrb5 library for MIT Kerberos V5 before 1.2.5 allows users from one realm to impersonate users in other realms that have the same inter-realm keys.

Multiple buffer overflows in Hypermail 2 before 2.1.6 allows remote attackers to cause a denial of service and possibly execute arbitrary code (1) via a long attachment filename that is not properly handled by the hypermail executable, or (2) by connecting to the mail CGI program from an IP address that reverse-resolves to a long hostname.

SQL injection vulnerability in the PostgreSQL auth module for courier 0.40 and earlier allows remote attackers to execute SQL code via the user name.

Format string vulnerability in mpmain.c for plpnfsd of the plptools package allows remote attackers to execute arbitrary code via the functions (1) debuglog, (2) errorlog, and (3) infolog.

Buffer overflow in Eset Software NOD32 for UNIX before 1.013 allows local users to execute arbitrary code via a long path name.

Buffer overflow in secure locate (slocate) before 2.7 allows local users to execute arbitrary code via a long (1) -c or (2) -r command line argument.

uml_net in the kernel-utils package for Red Hat Linux 8.0 has incorrect setuid root privileges, which allows local users to modify network interfaces, e.g.

Buffer overflow in the Windows Redirector function in Microsoft Windows XP allows local users to execute arbitrary code via a long parameter.

The default configuration of the pam_xauth module forwards MIT-Magic-Cookies to new X sessions, which could allow local users to gain root privileges by stealing the cookies from a temporary .xauth file, which is created with the original user's credentials after root uses su.

Unknown vulnerability in the directory parser for Direct Connect 4 Linux (dcgui) before 0.2.2 allows remote attackers to read files outside the sharelist.

Double-free vulnerability in mysqld for MySQL before 3.23.55 allows attackers with MySQL access to cause a denial of service (crash) via mysql_change_user.

MIT Kerberos V5 Key Distribution Center (KDC) before 1.2.5 allows remote authenticated attackers to cause a denial of service (crash) on KDCs within the same realm via a certain protocol request that causes a null dereference.

w3m before 0.3.2.2 does not properly escape HTML tags in the ALT attribute of an IMG tag, which could allow remote attackers to access files or cookies.

The web interface for Pingtel xpressa SIP-based voice-over-IP phone 1.2.5 through 1.2.7.4 allows administrators to cause a denial of service by modifying the SIP_AUTHENTICATE_SCHEME value to force authentication of incoming calls, which does not notify the user when an authentication failure occurs.

Integer signedness error in MIT Kerberos V5 ASN.1 decoder before krb5 1.2.5 allows remote attackers to cause a denial of service via a large unsigned data element length, which is later used as a negative value.

Unknown vulnerability in UDP RPC for Solaris 2.5.1 through 9 for SPARC, and 2.5.1 through 8 for x86, allows remote attackers to cause a denial of service (memory consumption) via certain arguments in RPC calls that cause large amounts of memory to be allocated.

PuTTY 0.53b and earlier does not clear logon credentials from memory, including plaintext passwords, which could allow attackers with access to memory to steal the SSH credentials.

SSH2 clients for VanDyke (1) SecureCRT 4.0.2 and 3.4.7, (2) SecureFX 2.1.2 and 2.0.4, and (3) Entunnel 1.0.2 and earlier, do not clear logon credentials from memory, including plaintext passwords, which could allow attackers with access to memory to steal the SSH credentials.

AbsoluteTelnet SSH2 client does not clear logon credentials from memory, including plaintext passwords, which could allow attackers with access to memory to steal the SSH credentials.

slapd in OpenLDAP2 (OpenLDAP 2) 2.2.0 and earlier allows local users to overwrite arbitrary files via a race condition during the creation of a log file for rejected replication requests.
