The Transmission Control Protocol (TCP) allows remote attackers to cause a denial of service (bandwidth consumption) by sending ACK messages for packets that have not yet been received (optimistic ACKs), which can cause the sender to increase its transmission rate until it fills available bandwidth.

The Internet Key Exchange version 1 (IKEv1) implementation in Openswan 2 (openswan-2) before 2.4.4, and freeswan in SUSE LINUX 9.1 before 2.04_1.5.4-1.23, allow remote attackers to cause a denial of service via (1) a crafted packet using 3DES with an invalid key length, or (2) unspecified inputs when Aggressive Mode is enabled and the PSK is known, as demonstrated by the PROTOS ISAKMP Test Suite for IKEv1.

Multiple cross-site scripting (XSS) vulnerabilities in phpMyAdmin before 2.7.0 allow remote attackers to inject arbitrary web script or HTML via the (1) HTTP_HOST variable and (2) various scripts in the libraries directory that handle header generation.

Off-by-one buffer overflow in pnmtopng before 2.39, when using the -alpha command line option (Alphas_Of_Color), allows attackers to cause a denial of service (crash) and possibly execute arbitrary code via a crafted PNM file with exactly 256 colors.

Linux kernel 2.4 and 2.6 allows attackers to cause a denial of service (memory exhaustion and panic) by creating a large number of connected file descriptors or socketpairs and setting a large data transfer buffer, then preventing Linux from being able to finish the transfer by causing the process to become a zombie, or closing the file descriptor without closing an associated reference.

Multiple format string vulnerabilities in logging functions in mod_auth_pgsql before 2.0.3, when used for user authentication against a PostgreSQL database, allows remote unauthenticated attackers to execute arbitrary code, as demonstrated via the username.

Stack-based buffer overflow in the dissect_ospf_v3_address_prefix function in the OSPF protocol dissector in Ethereal 0.10.12, and possibly other versions, allows remote attackers to execute arbitrary code via crafted packets.

jumpto.php in Moodle 1.5.2 allows remote attackers to redirect users to other sites via the jump parameter.

Multiple SQL injection vulnerabilities in the get_record function in datalib.php in Moodle 1.5.2 allow remote attackers to execute arbitrary SQL commands via the id parameter in (1) category.php and (2) info.php.

Multiple buffer overflows in pnmtopng in netpbm 10.0 and earlier allow attackers to execute arbitrary code via a crafted PNM file.

udev does not properly set permissions on certain files in /dev/input, which allows local users to obtain sensitive data that is entered at the console, such as user passwords.

Buffer overflow in the JBIG2Bitmap::JBIG2Bitmap function in JBIG2Stream.cc in Xpdf, as used in products such as gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others, allows attackers to modify memory and possibly execute arbitrary code via unknown attack vectors.

Stream.cc in Xpdf, as used in products such as gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others, allows attackers to modify memory and possibly execute arbitrary code via a DCTDecode stream with (1) a large "number of components" value that is not checked by DCTStream::readBaselineSOF or DCTStream::readProgressiveSOF, (2) a large "Huffman table index" value that is not checked by DCTStream::readHuffmanTables, and (3) certain uses of the scanInfo.numComps value by DCTStream::readScanInfo.

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.

Xpdf, as used in products such as gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others, allows attackers to cause a denial of service (infinite loop) via streams that end prematurely, as demonstrated using the (1) CCITTFaxDecode and (2) DCTDecode streams, aka "Infinite CPU spins."

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.

nfs2acl.c in the Linux kernel 2.6.14.4 does not check for MAY_SATTR privilege before setting access controls (ACL) on files on exported NFS filesystems, which allows remote attackers to bypass ACLs for readonly mounted NFS filesystems.

phpMyAdmin 2.7.0-beta1 and earlier allows remote attackers to obtain the full path of the server via direct requests to multiple scripts in the libraries directory.

CRLF injection vulnerability in phpMyAdmin before 2.6.4-pl4 allows remote attackers to conduct HTTP response splitting attacks via unspecified scripts.

The getgrouplist function in the GNU C library (glibc) before version 2.3.5, when invoked with a zero argument, writes to the passed pointer even if the specified array size is zero, leading to a buffer overflow and potentially allowing attackers to corrupt memory.
