Red Hat Linux 8.0

The mxcsr code in Linux kernel 2.4 allows attackers to modify CPU state registers via a malformed address.

Kerberos FTP client allows remote FTP sites to execute arbitrary code via a pipe (|) character in a filename that is retrieved by the client.

Various PDF viewers including (1) Adobe Acrobat 5.06 and (2) Xpdf 1.01 allow remote attackers to execute arbitrary commands via shell metacharacters in an embedded hyperlink.

The do_change_cipher_spec function in OpenSSL 0.9.6c to 0.9.6k, and 0.9.7a to 0.9.7c, allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that triggers a null dereference.

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.

Buffer overflow in KON kon2 0.3.9b and earlier allows local users to execute arbitrary code via a long -Coding command line argument.

uml_net in the kernel-utils package for Red Hat Linux 8.0 has incorrect setuid root privileges, which allows local users to modify network interfaces, e.g. by modifying ARP entries or placing interfaces into promiscuous mode.

Integer overflow in the ubsec_keysetup function for Linux Broadcom 5820 cryptonet driver allows local users to cause a denial of service (crash) and possibly execute arbitrary code via a negative add_dsa_buf_bytes variable, which leads to a buffer overflow.

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.

Gnutls: timing side-channel in the rsa-psk authentication

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.

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

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.

Cross-site scripting (XSS) vulnerability in the transparent SID support capability for PHP before 4.3.2 (session.use_trans_sid) allows remote attackers to insert arbitrary script via the PHPSESSID parameter.

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.

/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.
