dbus-daemon in D-Bus before 1.0.3, and 1.1.x before 1.1.20, recognizes send_interface attributes in allow directives in the security policy only for fully qualified method calls, which allows local users to bypass intended access restrictions via a method call with a NULL interface.

Stack-based buffer overflow in the zseticcspace function in zicc.c in Ghostscript 8.61 and earlier allows remote attackers to execute arbitrary code via a postscript (.ps) file containing a long Range array in a .seticcspace operator.

The xmlCurrentChar function in libxml2 before 2.6.31 allows context-dependent attackers to cause a denial of service (infinite loop) via XML containing invalid UTF-8 sequences.

Buffer overflow in the polymorphic opcode support in the Regular Expression Engine (regcomp.c) in Perl 5.8 allows context-dependent attackers to execute arbitrary code by switching from byte to Unicode (UTF) characters in a regular expression.

Off-by-one error in the QUtf8Decoder::toUnicode function in Trolltech Qt 3 allows context-dependent attackers to cause a denial of service (crash) via a crafted Unicode string that triggers a heap-based buffer overflow. NOTE: Qt 4 has the same error in the QUtf8Codec::convertToUnicode function, but it is not exploitable.

Heap-based buffer overflow in libmpdemux/aviheader.c in MPlayer 1.0rc1 and earlier allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a .avi file with certain large "indx truck size" and nEntriesInuse values, and a certain wLongsPerEntry value.

Emacs 21 allows user-assisted attackers to cause a denial of service (crash) via certain crafted images, as demonstrated via a GIF image in vm mode, related to image size calculation.

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.

Integer overflow in the FontFileInitTable function in X.Org libXfont before 20070403 allows remote authenticated users to execute arbitrary code via a long first line in the fonts.dir file, which results in a heap overflow.

Stack-based buffer overflow in the accept_att_local function in server/os/connection.c in Network Audio System (NAS) before 1.8a SVN 237 allows remote attackers to execute arbitrary code via a long path slave name in a USL socket connection.

Integer overflow in the ProcAuWriteElement function in server/dia/audispatch.c in Network Audio System (NAS) before 1.8a SVN 237 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a large max_samples value.

The AddResource function in server/dia/resource.c in Network Audio System (NAS) before 1.8a SVN 237 allows remote attackers to cause a denial of service (server crash) via a nonexistent client ID.

Array index error in Network Audio System (NAS) before 1.8a SVN 237 allows remote attackers to cause a denial of service (crash) via (1) large num_action values in the ProcAuSetElements function in server/dia/audispatch.c or (2) a large inputNum parameter to the compileInputs function in server/dia/auutil.c.

The ReadRequestFromClient function in server/os/io.c in Network Audio System (NAS) before 1.8a SVN 237 allows remote attackers to cause a denial of service (crash) via multiple simultaneous connections, which triggers a NULL pointer dereference.

kdesu in kdelibs package creates world readable temporary files containing authentication info, which can allow local users to gain privileges.

BitchX IRC client does not properly cleanse an untrusted format string, which allows remote attackers to cause a denial of service via an invite to a channel whose name includes special formatting characters.
