The Asterisk Extension Language (AEL) in pbx/pbx_ael.c in Asterisk does not properly generate extensions, which allows remote attackers to execute arbitrary extensions and have an unknown impact by specifying an invalid extension in a certain form.

The handle_response function in chan_sip.c in Asterisk before 1.2.17 and 1.4.x before 1.4.2 allows remote attackers to cause a denial of service (crash) via a SIP Response code 0 in a SIP packet.

net/ipv6/tcp_ipv6.c in Linux kernel 2.6.x up to 2.6.21-rc3 inadvertently copies the ipv6_fl_socklist from a listening TCP socket to child sockets, which allows local users to cause a denial of service (OOPS) or double free by opening a listening IPv6 socket, attaching a flow label, and connecting to that socket.

Buffer underflow in the header function in PHP 5.2.0 allows context-dependent attackers to execute arbitrary code by passing an all-whitespace string to this function, which causes it to write '\0' characters in whitespace that precedes the string.

The mb_parse_str function in PHP 4.0.0 through 4.4.6 and 5.0.0 through 5.2.1 sets the internal register_globals flag and does not disable it in certain cases when a script terminates, which allows remote attackers to invoke available PHP scripts with register_globals functionality that is not detectable by these scripts, as demonstrated by forcing a memory_limit violation.

The resource system in PHP 4.0.0 through 4.4.6 and 5.0.0 through 5.2.1 allows context-dependent attackers to execute arbitrary code by interrupting certain functions in the GD (ext/gd) extension and unspecified other extensions via a userspace error handler, which can be used to destroy and modify internal resources.

The resource system in PHP 5.0.0 through 5.2.1 allows context-dependent attackers to execute arbitrary code by interrupting the hash_update_file function via a userspace (1) error or (2) stream handler, which can then be used to destroy and modify internal resources. NOTE: it was later reported that PHP 5.2 through 5.2.13 and 5.3 through 5.3.2 are also affected.

Konqueror 3.5.5 allows remote attackers to cause a denial of service (crash) by using JavaScript to read a child iframe having an ftp:// URI.

The FTP protocol implementation in Konqueror 3.5.5 allows remote servers to force the client to connect to other servers, perform a proxied port scan, or obtain sensitive information by specifying an alternate server address in an FTP PASV response.

The FTP protocol implementation in Opera 9.10 allows remote attackers to allows remote servers to force the client to connect to other servers, perform a proxied port scan, or obtain sensitive information by specifying an alternate server address in an FTP PASV response.

The FTP protocol implementation in Mozilla Firefox before 1.5.0.11 and 2.x before 2.0.0.3 allows remote attackers to force the client to connect to other servers, perform a proxied port scan, or obtain sensitive information by specifying an alternate server address in an FTP PASV response.

The channel driver in Asterisk before 1.2.17 and 1.4.x before 1.4.2 allows remote attackers to cause a denial of service (crash) via a SIP INVITE message with an SDP containing one valid and one invalid IP address.

The clientProcessRequest() function in src/client_side.c in Squid 2.6 before 2.6.STABLE12 allows remote attackers to cause a denial of service (daemon crash) via crafted TRACE requests that trigger an assertion error.

The APOP protocol allows remote attackers to guess the first 3 characters of a password via man-in-the-middle (MITM) attacks that use crafted message IDs and MD5 collisions. NOTE: this design-level issue potentially affects all products that use APOP, including (1) Thunderbird 1.x before 1.5.0.12 and 2.x before 2.0.0.4, (2) Evolution, (3) mutt, (4) fetchmail before 6.3.8, (5) SeaMonkey 1.0.x before 1.0.9 and 1.1.x before 1.1.2, (6) Balsa 2.3.16 and earlier, (7) Mailfilter before 0.8.2, and possibly other products.

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.

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 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.

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.

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.

Directory traversal vulnerability in am.pl in SQL-Ledger 2.6.27 only checks for the presence of a NULL (%00) character to protect against directory traversal attacks, which allows remote attackers to run arbitrary executables and bypass authentication via a .. (dot dot) sequence in the login parameter.
