dvips converter for Postscript files in the tetex package calls the system() function insecurely, which allows remote attackers to execute arbitrary commands via certain print jobs, possibly involving fonts.

Unknown vulnerability in GNU Ghostscript before 7.07 allows attackers to execute arbitrary commands, even when -dSAFER is enabled, via a PostScript file that causes the commands to be executed from a malicious print job.

The bluez_sock_create 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.

lv reads a .lv file from the current working directory, which allows local users to execute arbitrary commands as other lv users by placing malicious .lv files into other directories.

The default configuration of the pam_xauth module forwards MIT-Magic-Cookies to new X sessions, which could allow local users to gain root privileges by stealing the cookies from a temporary .xauth file, which is created with the original user's credentials after root uses su.

Race condition in the (1) load_elf_library and (2) binfmt_aout function calls for uselib in Linux kernel 2.4 through 2.429-rc2 and 2.6 through 2.6.10 allows local users to execute arbitrary code by manipulating the VMA descriptor.

setpwnam.c in the util-linux package, as included in Red Hat Linux 7.3 and earlier, and other operating systems, does not properly lock a temporary file when modifying /etc/passwd, which may allow local users to gain privileges via a complex race condition that uses an open file descriptor in utility programs such as chfn and chsh.

The SSL/TLS handshaking code in OpenSSL 0.9.7a, 0.9.7b, and 0.9.7c, when using Kerberos ciphersuites, does not properly check the length of Kerberos tickets during a handshake, which allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that causes an out-of-bounds read.

OpenSSL 0.9.6 before 0.9.6d does not properly handle unknown message types, which allows remote attackers to cause a denial of service (infinite loop), as demonstrated using the Codenomicon TLS Test Tool.

The TCP/IP fragment reassembly handling in the Linux kernel 2.4 allows remote attackers to cause a denial of service (CPU consumption) via certain packets that cause a large number of hash table collisions.

Xpdf, as used in products such as gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others, allows attackers to cause a denial of service (crash) via a crafted FlateDecode stream that triggers a null dereference.

Memory leak in ypdb_open in yp_db.c for ypserv before 2.5 in the NIS package 3.9 and earlier allows remote attackers to cause a denial of service (memory consumption) via a large number of requests for a map that does not exist.

Unknown vulnerability in the TTY layer of the Linux kernel 2.4 allows attackers to cause a denial of service ("kernel oops").

The CCITTFaxStream::CCITTFaxStream function in Stream.cc for xpdf, gpdf, kpdf, pdftohtml, poppler, teTeX, CUPS, libextractor, and others allows attackers to corrupt the heap via negative or large integers in a CCITTFaxDecode stream, which lead to integer overflows and integer underflows.

Mozilla allows remote attackers to cause a denial of service (application crash from null dereference or infinite loop) via a web page that contains a (1) TEXTAREA, (2) INPUT, (3) FRAMESET or (4) IMG tag followed by a null character and some trailing characters, as demonstrated by mangleme.

The Internet Group Management Protocol (IGMP) allows local users to cause a denial of service via an IGMP membership report to a target's Ethernet address instead of the Multicast group address, which causes the target to stop sending reports to the router and effectively disconnect the group from the network.

Mozilla Firefox before the Preview Release, Mozilla before 1.7.3, and Thunderbird before 0.8 allows remote attackers to perform cross-domain scripting and possibly execute arbitrary code by convincing a user to drag and drop javascript: links to a frame or page in another domain.

The RPC code in Linux kernel 2.4 sets the reuse flag when sockets are created, which could allow local users to bind to UDP ports that are used by privileged services such as nfsd.

tcpdump does not properly drop privileges to the pcap user when starting up.

A patch for shadow-utils 20000902 causes the useradd command to create a mail spool files with read/write privileges of the new user's group (mode 660), which allows other users in the same group to read or modify the new user's incoming email.

Memory leak in the ip_options_get function in the Linux kernel before 2.6.10 allows local users to cause a denial of service (memory consumption) by repeatedly calling the ip_cmsg_send function.

Integer overflow in the vc_resize function in the Linux kernel 2.4 and 2.6 before 2.6.10 allows local users to cause a denial of service (kernel crash) via a short new screen value, which leads to a buffer overflow.

Integer overflow in the ip_options_get function in the Linux kernel before 2.6.10 allows local users to cause a denial of service (kernel crash) via a cmsg_len that contains a -1, which leads to a buffer overflow.

/proc/tty/driver/serial in Linux 2.4.x reveals the exact number of characters used in serial links, which could allow local users to obtain potentially sensitive information such as the length of passwords.
