Buffer overflow in ntpd ntp daemon 4.0.99k and earlier (aka xntpd and xntp3) allows remote attackers to cause a denial of service and possibly execute arbitrary commands via a long readvar argument.

vim (aka gvim) processes VIM control codes that are embedded in a file, which could allow attackers to execute arbitrary commands when another user opens a file containing malicious VIM control codes.

Samba before 2.2.0 allows local attackers to overwrite arbitrary files via a symlink attack using (1) a printer queue query, (2) the more command in smbclient, or (3) the mput command in smbclient.

ip_conntrack_ftp in the IPTables firewall for Linux 2.4 allows remote attackers to bypass access restrictions for an FTP server via a PORT command that lists an arbitrary IP address and port number, which is added to the RELATED table and allowed by the firewall.

The OpenPGP PGP standard allows an attacker to determine the private signature key via a cryptanalytic attack in which the attacker alters the encrypted private key file and captures a single message signed with the signature key.

TCP implementations that use random increments for initial sequence numbers (ISN) can allow remote attackers to perform session hijacking or disruption by injecting a flood of packets with a range of ISN values, one of which may match the expected ISN.

Race condition in ptrace in Linux kernel 2.4 and 2.2 allows local users to gain privileges by using ptrace to track and modify a running setuid process.

Linux kernel 2.4 and 2.2 allows local users to read kernel memory and possibly gain privileges via a negative argument to the sysctl call.

inetd in Red Hat 6.2 does not properly close sockets for internal services such as chargen, daytime, echo, etc., which allows remote attackers to cause a denial of service via a series of connections to the internal services.

Buffer overflow in Analog before 4.16 allows remote attackers to execute arbitrary commands by using the ALIAS command to construct large strings.

Joe text editor 2.8 searches the current working directory (CWD) for the .joerc configuration file, which could allow local users to gain privileges of other users by placing a Trojan Horse .joerc file into a directory, then waiting for users to execute joe from that directory.

Buffer overflow in sudo earlier than 1.6.3p6 allows local users to gain root privileges.

Buffer overflow in micq client 0.4.6 and earlier allows remote attackers to cause a denial of service, and possibly execute arbitrary commands, via a long Description field.

Format string vulnerability in print_client in icecast 1.3.8beta2 and earlier allows remote attackers to execute arbitrary commands.

gnuserv before 3.12, as shipped with XEmacs, does not properly check the specified length of an X Windows MIT-MAGIC-COOKIE cookie, which allows remote attackers to execute arbitrary commands via a buffer overflow, or brute force authentication by using a short cookie length.

glibc 2.1.9x and earlier does not properly clear the RESOLV_HOST_CONF, HOSTALIASES, or RES_OPTIONS environmental variables when executing setuid/setgid programs, which could allow local users to read arbitrary files.

When using the LD_PRELOAD environmental variable in SUID or SGID applications, glibc does not verify that preloaded libraries in /etc/ld.so.cache are also SUID/SGID, which could allow a local user to overwrite arbitrary files by loading a library from /lib or /usr/lib.

mgetty 1.1.22 allows local users to overwrite arbitrary files via a symlink attack in some configurations.

htpasswd and htdigest in Apache 2.0a9, 1.3.14, and others allows local users to overwrite arbitrary files via a symlink attack.

Zope before 2.2.4 does not properly compute local roles, which could allow users to bypass specified access restrictions and gain privileges.
