Redhat : Security Vulnerabilities, CVEs, Published In 2001 (Denial of service)

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.

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.

TUX HTTP server 2.1.0-2 in Red Hat Linux allows remote attackers to cause a denial of service via a long Host: header.

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.

apmscript in Apmd in Red Hat 7.2 "Enigma" allows local users to create or change the modification dates of arbitrary files via a symlink attack on the LOW_POWER temporary file, which could be used to cause a denial of service, e.g. by creating /etc/nologin and disabling logins.
