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

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.

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.

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.

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.

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.

Off-by-one error in the channel code of OpenSSH 2.0 through 3.0.2 allows local users or remote malicious servers to gain privileges.

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.

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

Squid 2.4 STABLE3 and earlier allows remote attackers to cause a denial of service (core dump) and possibly execute arbitrary code with an ftp:// URL with a larger number of special characters, which exceed the buffer when Squid URL-escapes the characters.

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.

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."

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.

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.

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.

tcl/tk package (tcltk) 8.3.1 searches for its libraries in the current working directory before other directories, which could allow local users to execute arbitrary code via a Trojan horse library that is under a user-controlled directory.

expect before 5.32 searches for its libraries in /var/tmp before other directories, which could allow local users to gain root privileges via a Trojan horse library that is accessed by mkpasswd.

Squid before 2.3STABLE5 in HTTP accelerator mode does not enable access control lists (ACLs) when the httpd_accel_host and http_accel_with_proxy off settings are used, which allows attackers to bypass the ACLs and conduct unauthorized activities such as port scanning.

Apache on Red Hat Linux with with the UserDir directive enabled generates different error codes when a username exists and there is no public_html directory and when the username does not exist, which could allow remote attackers to determine valid usernames on the server.

The default configuration of the DVI print filter (dvips) in Red Hat Linux 7.0 and earlier does not run dvips in secure mode when dvips is executed by lpd, which could allow remote attackers to gain privileges by printing a DVI file that contains malicious commands.

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.

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.

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.

Format string vulnerability in the default logging callback function _sasl_syslog in common.c in Cyrus SASL library (cyrus-sasl) may allow remote attackers to execute arbitrary commands.
