Squid 2.4 STABLE3 and earlier does not properly disable HTCP, even when "htcp_port 0" is specified in squid.conf, which could allow remote attackers to bypass intended access restrictions.

slapd in OpenLDAP 2.0 through 2.0.19 allows local users, and anonymous users before 2.0.8, to conduct a "replace" action on access controls without any values, which causes OpenLDAP to delete non-mandatory attributes that would otherwise be protected by ACLs.

Konqueror Embedded and KDE 2.2.2 and earlier does not validate the Common Name (CN) field for X.509 Certificates, which could allow remote attackers to spoof certificates via a man-in-the-middle attack.

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.

Heap corruption vulnerability in the "at" program allows local users to execute arbitrary code via a malformed execution time, which causes at to free the same memory twice.

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

OpenSSH 3.0.1 and earlier with UseLogin enabled does not properly cleanse critical environment variables such as LD_PRELOAD, which allows local users to gain root privileges.

Buffer overflow in newt.c of newt windowing library (libnewt) 0.50.33 and earlier may allow attackers to cause a denial of service or execute arbitrary code in setuid programs that use libnewt.

Buffer overflow in ncurses 5.0, and the ncurses4 compatibility package as used in Red Hat Linux, allows local users to gain privileges, related to "routines for moving the physical cursor and scrolling."

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.

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.

initscript in setserial 2.17-4 and earlier uses predictable temporary file names, which could allow local users to conduct unauthorized operations on files.

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.

slapd in OpenLDAP 1.x before 1.2.12, and 2.x before 2.0.8, allows remote attackers to cause a denial of service (crash) via an invalid Basic Encoding Rules (BER) length field.

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").

2.4.3-12 kernel in Red Hat Linux 7.1 Korean installation program sets the setting default umask for init to 000, which installs files with world-writeable permissions.

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.

Buffer overflow in efstools in Bonobo, when installed setuid, allows local users to execute arbitrary code via long command line arguments.

LPRng in Red Hat Linux 7.0 and 7.1 does not properly drop memberships in supplemental groups when lowering privileges, which could allow a local user to elevate privileges.

Buffer overflow in glob function of glibc allows attackers to cause a denial of service (crash) and possibly execute arbitrary code via a glob pattern that ends in a brace "{" character.

kdesu in kdelibs package creates world readable temporary files containing authentication info, which can allow local users to gain privileges.

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.

Red Hat Linux 7.1 sets insecure permissions on swap files created during installation, which can allow a local attacker to gain additional privileges by reading sensitive information from the swap file, such as passwords.

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

GNU Enscript 1.6.1 and earlier allows local users to overwrite arbitrary files of the Enscript user via a symlink attack on temporary files.

Memory leak in SNMP in Squid 2.4 STABLE3 and earlier allows remote attackers to cause a denial of service.

rsync, when running in daemon mode, does not properly call setgroups before dropping privileges, which could provide supplemental group privileges to local users, who could then read certain files that would otherwise be disallowed.

/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.

BEA WebLogic Express and WebLogic Server 7.0 and 7.0.0.1, stores passwords in plaintext when a keystore is used to store a private key or trust certificate authorities, which allows local users to gain access.
