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."

Multiple vulnerabilities in the IGMP functionality for Linux kernel 2.4.22 to 2.4.28, and 2.6.x to 2.6.9, allow local and remote attackers to cause a denial of service or execute arbitrary code via (1) the ipmcsource function, which decrements a counter to -1, or (2) the igmpmarksources function, which does not properly validate IGMP message parameters and performs an out-of-bounds read.

Buffer overflow in the MSN protocol handler for gaim 0.79 to 1.0.1 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via an "unexpected sequence of MSNSLP messages" that results in an unbounded copy operation that writes to the wrong buffer.

Buffer overflow in the QFILEPATHINFO request handler in Samba 3.0.x through 3.0.7 may allow remote attackers to execute arbitrary code via a TRANSACT2QFILEPATHINFO request with a small "maximum data bytes" value.

Multiple integer overflows in xpdf 3.0, and other packages that use xpdf code such as CUPS, allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code, a different set of vulnerabilities than those identified by CVE-2004-0888.

Multiple integer overflows in xpdf 2.0 and 3.0, and other packages that use xpdf code such as CUPS, gpdf, and kdegraphics, allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code, a different set of vulnerabilities than those identified by CVE-2004-0889.

The argument parser of the FETCH command in Cyrus IMAP Server 2.2.x through 2.2.8 allows remote authenticated users to execute arbitrary code via certain commands such as (1) "body[p", (2) "binary[p", or (3) "binary[p") that cause an index increment error that leads to an out-of-bounds memory corruption.

The deserialization code in PHP before 4.3.10 and PHP 5.x up to 5.0.2 allows remote attackers to cause a denial of service and execute arbitrary code via untrusted data to the unserialize function that may trigger "information disclosure, double-free and negative reference index array underflow" results.

Stack-based buffer overflow in Cyrus IMAP Server 2.2.4 through 2.2.8, with the imapmagicplus option enabled, allows remote attackers to execute arbitrary code via a long (1) PROXY or (2) LOGIN command, a different vulnerability than CVE-2004-1015.

Buffer overflow in proxyd for Cyrus IMAP Server 2.2.9 and earlier, with the imapmagicplus option enabled, may allow remote attackers to execute arbitrary code, a different vulnerability than CVE-2004-1011.

The argument parser of the PARTIAL command in Cyrus IMAP Server 2.2.6 and earlier allows remote authenticated users to execute arbitrary code via a certain command ("body[p") that is treated as a different command ("body.peek") and causes an index increment error that leads to an out-of-bounds memory corruption.

Buffer overflow in the exifreaddata function in PHP before 4.3.10 and PHP 5.x up to 5.0.2 allows remote attackers to execute arbitrary code via a long section name in an image file.

Multiple buffer overflows in libXML 2.6.12 and 2.6.13 (libxml2), and possibly other versions, may allow remote attackers to execute arbitrary code via (1) a long FTP URL that is not properly handled by the xmlNanoFTPScanURL function, (2) a long proxy URL containing FTP data that is not properly handled by the xmlNanoFTPScanProxy function, and other overflows related to manipulation of DNS length values, including (3) xmlNanoFTPConnect, (4) xmlNanoHTTPConnectHost, and (5) xmlNanoHTTPConnectHost.

Off-by-one error in the mysaslcanonuser function in Cyrus IMAP Server 2.2.9 and earlier leads to a buffer overflow, which may allow remote attackers to execute arbitrary code via the username.

A "stack overwrite" vulnerability in GnuPG (gpg) 1.x before 1.4.6, 2.x before 2.0.2, and 1.9.0 through 1.9.95 allows attackers to execute arbitrary code via crafted OpenPGP packets that cause GnuPG to dereference a function pointer from deallocated stack memory.

Integer overflow in the bdfReadCharacters function in bdfread.c in (1) X.Org libXfont before 20070403 and (2) freetype 2.3.2 and earlier allows remote authenticated users to execute arbitrary code via crafted BDF fonts, which result in a heap overflow.

The enigmail extension before 0.94.2 does not properly handle large, encrypted file e-mail attachments, which allows remote attackers to cause a denial of service (crash), as demonstrated with Mozilla Thunderbird.

The patch for integer overflow vulnerabilities in Xpdf 2.0 and 3.0 (CVE-2004-0888) is incomplete for 64-bit architectures on certain Linux distributions such as Red Hat, which could leave Xpdf users exposed to the original vulnerabilities.

Kommander in KDE 3.2 through KDE 3.4.0 executes data files without confirmation from the user, which allows remote attackers to execute arbitrary code.

Multiple buffer overflows in the ImageMagick graphics library 5.x before 5.4.4, and 6.x before 6.0.6.2, allow remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via malformed (1) AVI, (2) BMP, or (3) DIB files.

Multiple heap-based buffer overflows in the imlib BMP image handler allow remote attackers to execute arbitrary code via a crafted BMP file.

Dirk Mueller reported an off by one buffer overflow flaw in the way QT parses certain unicode strings.

To quote Dirk:

Ive found a off-by-one buffer overflow in QUtf8Decoder::toUnicode(). It is not exploitable with Qt 4.x or above because there is an additional QChar(0) being allocated in QString, however it is still a bug there, as the array returned by utf16() etc is no longer terminated properly.

The bluezsockcreate function in the Bluetooth stack for Linux kernel 2.4.6 through 2.4.30-rc1 and 2.6 through 2.6.11.5 allows local users to gain privileges via (1) socket or (2) socketpair call with a negative protocol value.

The Ubuntu 5.10 installer does not properly clear passwords from the installer log file (questions.dat), and leaves the log file with world-readable permissions, which allows local users to gain privileges.

sudo 1.6.8 and other versions does not clear the PYTHONINSPECT environment variable, which allows limited local users to gain privileges via a Python script, a variant of CVE-2005-4158.

Multiple buffer overflows in the (1) sys32nisyscall and (2) sys32vm86warning functions in sysia32.c for Linux 2.6.x may allow local attackers to modify kernel memory and gain privileges.

sudo before 1.6.8p2 allows local users to execute arbitrary commands by using "()" style environment variables to create functions that have the same name as any program within the bash script that is called without using the program's full pathname.

The POSIX Capability Linux Security Module (LSM) for Linux kernel 2.6 does not properly handle the credentials of a process that is launched before the module is loaded, which allows local users to gain privileges.

passwd before 1:4.0.13 on Ubuntu 6.06 LTS leaves the root password blank instead of locking it when the administrator selects the "Go Back" option after the final "Installation complete" message and uses the main menu, which causes the password to be zeroed out in the installer's memory.
