XScreenSaver 4.10, when using a remote directory service for credentials, does not properly handle the results from the getpwuid function in drivers/lock.c when there is no network connectivity, which causes XScreenSaver to crash and unlock the screen and allows local users to bypass authentication.
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.
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 secure script in LogWatch before 2.6-2 allows attackers to prevent LogWatch from detecting malicious activity via certain strings in the secure file that are later used as part of a regular expression, which causes the parser to crash, aka "logwatch log processing regular expression DoS."
Buffer overflow in Sylpheed before 1.0.3 and other versions before 1.9.5 allows remote attackers to execute arbitrary code via an e-mail message with certain headers containing non-ASCII characters that are not properly handled when the user replies to the message.
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.
Midnight commander (mc) 4.5.55 and earlier allows remote attackers to cause a denial of service (infinite loop) via unknown attack vectors.
direntry.c in Midnight Commander (mc) 4.5.55 and earlier allows attackers to cause a denial of service by "manipulating non-existing file handles."
Midnight commander (mc) 4.5.55 and earlier allows remote attackers to cause a denial of service by triggering a null dereference.
Midnight commander (mc) 4.5.55 and earlier allows remote attackers to cause a denial of service via "a corrupt section header."
Midnight commander (mc) 4.5.55 and earlier allows remote attackers to cause a denial of service via "use of already freed memory."
Midnight commander (mc) 4.5.55 and earlier allows remote attackers to cause a denial of service by causing mc to free unallocated memory.
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.
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.
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.
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.
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 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.
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.
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.
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.
The iSNS dissector for Ethereal 0.10.3 through 0.10.4 allows remote attackers to cause a denial of service (process abort) via an integer overflow.
The SMB SID snooping capability in Ethereal 0.9.15 to 0.10.4 allows remote attackers to cause a denial of service (process crash) via a handle without a policy name, which causes a null dereference.
The SNMP dissector in Ethereal 0.8.15 through 0.10.4 allows remote attackers to cause a denial of service (process crash) via a (1) malformed or (2) missing community string, which causes an out-of-bounds read.

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.
gdk-pixbuf before 0.20 allows attackers to cause a denial of service (crash) via a malformed bitmap (BMP) file.
The getifaddrs function in GNU libc (glibc) 2.2.4 and earlier allows local users to cause a denial of service by sending spoofed messages as other users to the kernel netlink interface.
