Common Unix Printing System (CUPS) 1.1.14 through 1.1.17 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code by causing negative arguments to be fed into memcpy() calls via HTTP requests with (1) a negative Content-Length value or (2) a negative length in a chunked transfer encoding.

Common Unix Printing System (CUPS) 1.1.14 through 1.1.17 allows remote attackers to add printers without authentication via a certain UDP packet, which can then be used to perform unauthorized activities such as stealing the local root certificate for the administration server via a "need authorization" page, as demonstrated by new-coke.

Common Unix Printing System (CUPS) 1.1.14 through 1.1.17 allows local users with lp privileges to create or overwrite arbitrary files via file race conditions, as demonstrated by ice-cream.

Heap-based buffer overflow in Fetchmail 6.1.3 and earlier does not account for the "@" character when determining buffer lengths for local addresses, which allows remote attackers to execute arbitrary code via a header with a large number of local addresses.

Portable Network Graphics (PNG) library libpng 1.2.5 and earlier does not correctly calculate offsets, which allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via a buffer overflow attack on the row buffers.

mICQ 0.4.9 and earlier allows remote attackers to cause a denial of service (crash) via malformed ICQ message types without a 0xFE separator character.

Ethereal 0.9.7 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via malformed packets to the (1) LMP, (2) PPP, or (3) TDS dissectors, possibly related to a missing field for EndVerifyAck messages.

Multiple integer signedness errors in the BGP dissector in Ethereal 0.9.7 and earlier allow remote attackers to cause a denial of service (infinite loop) via malformed messages.

The BGP decoding routines in tcpdump 3.6.x before 3.7 do not properly copy data, which allows remote attackers to cause a denial of service (application crash).

w3m before 0.3.2.2 does not properly escape HTML tags in the ALT attribute of an IMG tag, which could allow remote attackers to access files or cookies.

Multiple buffer overflows in Cyrus SASL library 2.1.9 and earlier allow remote attackers to cause a denial of service and possibly execute arbitrary code via (1) long inputs during user name canonicalization, (2) characters that need to be escaped during LDAP authentication using saslauthd, or (3) an off-by-one error in the log writer, which does not allocate space for the null character that terminates a string.

Directory traversal vulnerability in wget before 1.8.2-4 allows a remote FTP server to create or overwrite files as the wget user via filenames containing (1) /absolute/path or (2) .. (dot dot) sequences.

Cross-site scripting (XSS) vulnerability in read_body.php for SquirrelMail 1.2.10, 1.2.9, and earlier allows remote attackers to insert script and HTML via the (1) mailbox and (2) passed_id parameters.

Buffer overflow in Sendmail 5.79 to 8.12.7 allows remote attackers to execute arbitrary code via certain formatted address fields, related to sender and recipient header comments as processed by the crackaddr function of headers.c.

TightVNC before 1.2.6 generates the same challenge string for multiple connections, which allows remote attackers to bypass VNC authentication by sniffing the challenge and response of other users.

Cross-site scripting (XSS) vulnerability in w3m 0.3.2 does not escape an HTML tag in a frame, which allows remote attackers to insert arbitrary web script or HTML and access files or cookies.

Safe.pm 2.0.7 and earlier, when used in Perl 5.8.0 and earlier, may allow attackers to break out of safe compartments in (1) Safe::reval or (2) Safe::rdo using a redefined @_ variable, which is not reset between successive calls.

Pine 4.44 and earlier allows remote attackers to cause a denial of service (core dump and failed restart) via an email message with a From header that contains a large number of quotation marks (").

The Linux kernel 2.4.20 and earlier, and 2.5.x, when running on x86 systems, allows local users to cause a denial of service (hang) via the emulation mode, which does not properly clear TF and NT EFLAGs.

Buffer overflow in samba 2.2.2 through 2.2.6 allows remote attackers to cause a denial of service and possibly execute arbitrary code via an encrypted password that causes the overflow during decryption in which a DOS codepage string is converted to a little-endian UCS2 unicode string.
