Weekly Vulnerabilities Reports > December 23 to 29, 2002

Common Unix Printing System (CUPS) 1.1.14 through 1.1.17 does not properly check the return values of various file and socket operations, which could allow a remote attacker to cause a denial of service (resource exhaustion) by causing file descriptors to be assigned and not released, as demonstrated by fanta.

Portable Network Graphics (PNG) library libpng 1.2.5 and earlier does not correctly calculate offsets, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a buffer overflow attack on the row buffers.

Buffer overflow in the Windows Shell function in Microsoft Windows XP allows remote attackers to execute arbitrary code via an .MP3 or .WMA audio file with a corrupt custom attribute, aka "Unchecked Buffer in Windows Shell Could Enable System Compromise."

Multiple buffer overflows in Winamp 3.0, when displaying an MP3 in the Media Library window, allows remote attackers to execute arbitrary code via an MP3 file containing a long (1) Artist or (2) Album ID3v2 tag.

Buffer overflow in Winamp 2.81 allows remote attackers to execute arbitrary code via a long Artist ID3v2 tag in an MP3 file.

Macromedia Flash Player before 6.0.65.0 allows remote attackers to execute arbitrary code via certain malformed data headers in Shockwave Flash file format (SWF) files, a different issue than CAN-2002-0846.

libmysqlclient client library in MySQL 3.x to 3.23.54, and 4.x to 4.0.6, does not properly verify length fields for certain responses in the (1) read_rows or (2) read_one_row routines, which allows remote attackers to cause a denial of service and possibly execute arbitrary code.

Heap-based buffer overflow in Fetchmail 6.1.3 and earlier does not account for the "@" character when determining buffer lengths for local addresses, which allows remote attackers to execute arbitrary code via a header with a large number of local addresses.

The BGP decoding routines in tcpdump 3.6.x before 3.7 do not properly copy data, which allows remote attackers to cause a denial of service (application crash).

The Java Database Connectivity (JDBC) APIs in Microsoft Virtual Machine (VM) 5.0.3805 and earlier allow remote attackers to bypass security checks and access database contents via an untrusted Java applet.

openwebmail_init in Open WebMail 1.81 and earlier allows local users to execute arbitrary code via ..

Format string vulnerability in daemon.c for Exim 4.x through 4.10, and 3.x through 3.36, allows exim administrative users to execute arbitrary code by modifying the pid_file_path value.

Buffer overflow in the get_origin function in traceroute-nanog allows attackers to execute arbitrary code via long WHOIS responses.

Directory traversal vulnerability in priocntl system call in Solaris does allows local users to execute arbitrary code via ".." sequences in the pc_clname field of a pcinfo_t structure, which cause priocntl to load a malicious kernel module.

Buffer overflow in Melange Chat System 1.10 allows remote attackers to cause a denial of service (chat server crash) and possibly execute arbitrary code via the msgText buffer in the chat_InterpretData function, as demonstrated via a long Nick (nickname) request.

Signed integer vulnerability in the COM_TABLE_DUMP package for MySQL 3.23.x before 3.23.54 allows remote attackers to cause a denial of service (crash or hang) in mysqld by causing large negative integers to be provided to a memcpy call.

mICQ 0.4.9 and earlier allows remote attackers to cause a denial of service (crash) via malformed ICQ message types without a 0xFE separator character.

Microsoft Virtual Machine (VM) build 5.0.3805 and earlier allows remote attackers to determine a local user's username via a Java applet that accesses the user.dir system property, aka "User.dir Exposure Vulnerability."

Two vulnerabilities in Microsoft Virtual Machine (VM) up to and including build 5.0.3805, as used in Internet Explorer and other applications, allow remote attackers to read files via a Java applet with a spoofed location in the CODEBASE parameter in the APPLET tag, possibly due to a parsing error.

The SMB signing capability in the Server Message Block (SMB) protocol in Microsoft Windows 2000 and Windows XP allows attackers to disable the digital signing settings in an SMB session to force the data to be sent unsigned, then inject data into the session without detection, e.g.

vim 6.0 and 6.1, and possibly other versions, allows attackers to execute arbitrary commands using the libcall feature in modelines, which are not sandboxed but may be executed when vim is used to edit a malicious file, as demonstrated using mutt.

Linux kernel 2.2.x allows local users to cause a denial of service (crash) by using the mmap() function with a PROT_READ parameter to access non-readable memory pages through the /proc/pid/mem interface.
