Hyper-Threading technology, as used in FreeBSD and other operating systems that are run on Intel Pentium and other processors, allows local users to use a malicious thread to create covert channels, monitor the execution of other threads, and obtain sensitive information such as cryptographic keys, via a timing attack on memory cache misses.
The Internet Group Management Protocol (IGMP) allows local users to cause a denial of service via an IGMP membership report to a target's Ethernet address instead of the Multicast group address, which causes the target to stop sending reports to the router and effectively disconnect the group from the network.
Mozilla allows remote attackers to cause a denial of service (application crash from null dereference or infinite loop) via a web page that contains a (1) TEXTAREA, (2) INPUT, (3) FRAMESET or (4) IMG tag followed by a null character and some trailing characters, as demonstrated by mangleme.
Race condition in the (1) loadelflibrary and (2) binfmtaout function calls for uselib in Linux kernel 2.4 through 2.429-rc2 and 2.6 through 2.6.10 allows local users to execute arbitrary code by manipulating the VMA descriptor.
Unknown vulnerability in the DICOM dissector in Ethereal 0.10.4 through 0.10.7 allows remote attackers to cause a denial of service (application crash).
Multiple vulnerabilities in Konqueror in KDE 3.3.1 and earlier (1) allow access to restricted Java classes via JavaScript and (2) do not properly restrict access to certain Java classes from the Java applet, which allows remote attackers to bypass sandbox restrictions and read or write arbitrary files.
Ethereal 0.9.0 through 0.10.7 allows remote attackers to cause a denial of service (CPU consumption) via a certain malformed SMB packet.
A "missing serialization" error in the unixdgramrecvmsg function in Linux 2.4.27 and earlier, and 2.6.x up to 2.6.9, allows local users to gain privileges via a race condition.
statd in nfs-utils 1.257 and earlier does not ignore the SIGPIPE signal, which allows remote attackers to cause a denial of service (server process crash) via a TCP connection that is prematurely terminated.
The smbrecvtrans2 function call in the samba filesystem (smbfs) in Linux kernel 2.4 and 2.6 does not properly handle the re-assembly of fragmented packets correctly, which could allow remote samba servers to (1) read arbitrary kernel information or (2) raise a counter value to an arbitrary number by sending the first part of the fragmented packet multiple times.
Unknown vulnerability in MySQL 3.23.58 and earlier, when a local user has privileges for a database whose name includes a "" (underscore), grants privileges to other databases that have similar names, which can allow the user to conduct unauthorized activities.
The msfnmatch function in Samba 3.0.4 and 3.0.7 and possibly other versions allows remote authenticated users to cause a denial of service (CPU consumption) via a SAMBA request that contains multiple (wildcard) characters.
Multiple vulnerabilities in the samba filesystem (smbfs) in Linux kernel 2.4 and 2.6 allow remote samba servers to cause a denial of service (crash) or gain sensitive information from kernel memory via a samba server (1) returning more data than requested to the smbprocread function, (2) returning a data offset from outside the samba packet to the smbprocreadX function, (3) sending a certain TRANS2 fragmented packet to the smbreceivetrans2 function, (4) sending a samba packet with a certain header size to the smbprocreadXdata function, or (5) sending a certain packet based offset for the data in a packet to the smbreceivetrans2 function.
Mozilla Firefox before the Preview Release, Mozilla before 1.7.3, and Thunderbird before 0.8 allows remote attackers to perform cross-domain scripting and possibly execute arbitrary code by convincing a user to drag and drop javascript: links to a frame or page in another domain.
Multiple integer overflows in libtiff 3.6.1 and earlier allow remote attackers to cause a denial of service (crash or memory corruption) via TIFF images that lead to incorrect malloc calls.
The moddav module in Apache 2.0.50 and earlier allows remote attackers to cause a denial of service (child process crash) via a certain sequence of LOCK requests for a location that allows WebDAV authoring access.
Buffer overflow in the BMP loader in imlib2 before 1.1.2 allows remote attackers to execute arbitrary code via a specially-crafted BMP image, a different vulnerability than CVE-2004-0817.
Certain USB drivers in the Linux 2.4 kernel use the copytouser function on uninitialized structures, which could allow local users to obtain sensitive information by reading memory that was not cleared from previous usage.
Double free vulnerability in the krb5rdcred function for MIT Kerberos 5 (krb5) 1.3.1 and earlier may allow local users to execute arbitrary code.

In the pngformatbuffer function located in pngerror.c around line 133 is the following code:
if (message == NULL) buffer[iout] = 0; else { buffer[iout++] = ':'; buffer[iout++] = ' '; pngmemcpy(buffer+iout, message, 64); buffer[iout+63] = 0; } This code is called from the pngchunkerror & pngchunkwarning functions. An example of their use would be in pngutil.c around line 119. pngchunkerror(pngptr, "CRC error"); In the above code, the message being constructed is only 10 characters long. The pngmemcpy function will unconditionally access 54 bytes beyond the message.
This could cause a carefully crafted png image to cause a denial of service.
Possibly embargoed; marking as embargoed until communicated otherwise.
The SSL/TLS handshaking code in OpenSSL 0.9.7a, 0.9.7b, and 0.9.7c, when using Kerberos ciphersuites, does not properly check the length of Kerberos tickets during a handshake, which allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that causes an out-of-bounds read.
OpenSSL 0.9.6 before 0.9.6d does not properly handle unknown message types, which allows remote attackers to cause a denial of service (infinite loop), as demonstrated using the Codenomicon TLS Test Tool.
Xpdf, as used in products such as gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others, allows attackers to cause a denial of service (crash) via a crafted FlateDecode stream that triggers a null dereference.
The CCITTFaxStream::CCITTFaxStream function in Stream.cc for xpdf, gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others allows attackers to corrupt the heap via negative or large integers in a CCITTFaxDecode stream, which lead to integer overflows and integer underflows.
Memory leak in the worker MPM (worker.c) for Apache 2, in certain circumstances, allows remote attackers to cause a denial of service (memory consumption) via aborted connections, which prevents the memory for the transaction pool from being reused for other connections.
Off-by-one error in the modssl Certificate Revocation List (CRL) verification callback in Apache, when configured to use a CRL, allows remote attackers to cause a denial of service (child process crash) via a CRL that causes a buffer overflow of one null byte.
Stack-based buffer overflow in the ieeeputascii function for nasm 0.98 and earlier allows attackers to execute arbitrary code via a crafted asm file, a different vulnerability than CVE-2004-1287.
The KAME racoon daemon in ipsec-tools before 0.5 allows remote attackers to cause a denial of service (crash) via malformed ISAKMP packets.
Race condition in the page fault handler (fault.c) for Linux kernel 2.2.x to 2.2.7, 2.4 to 2.4.29, and 2.6 to 2.6.10, when running on multiprocessor machines, allows local users to execute arbitrary code via concurrent threads that share the same virtual memory space and simultaneously request stack expansion.
The KDE screen saver in KDE before 3.0.5 does not properly check the return value from a certain function call, which allows attackers with physical access to cause a crash and access the desktop session.
