perl regular expression UTF parsing errors

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.

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.

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.

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.

Xdg-utils 1.0.2 and earlier allows user-assisted remote attackers to execute arbitrary commands via shell metacharacters in a URL argument to (1) xdg-open or (2) xdg-email.

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.

Multiple font integer overflows (CVE-2007-1352)

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.

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.

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.

QT off by one buffer overflow

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.

libxml2: infinite loop in UTF-8 decoding

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.

The pa_drop_root function in PulseAudio 0.9.8, and a certain 0.9.9 build, does not check return values from (1) setresuid, (2) setreuid, (3) setuid, and (4) seteuid calls when attempting to drop privileges, which might allow local users to gain privileges by causing those calls to fail via attacks such as resource exhaustion.

ghostscript: stack-based buffer overflow in .seticcspace operator

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.

dbus security policy circumvention

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.

Format string vulnerability in the afsacl.so VFS module in Samba 3.0.6 through 3.0.23d allows context-dependent attackers to execute arbitrary code via format string specifiers in a filename on an AFS file system, which is not properly handled during Windows ACL mapping.

Multiple font integer overflows (CVE-2007-1352)

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.

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.

A race condition in MandrakeUpdate allows local users to modify RPM files while they are in the /tmp directory before they are installed.

security flaw

Vulnerability in Mandrake Linux usermode package allows local users to to reboot or halt the system.

security flaw

Linux OpenLDAP server allows local users to modify arbitrary files via a symlink attack.
