___
Date Reported: 12/30/97
Vulnerability: apache-dos
Platforms Affected: Apache httpd (1.2.x, 1.3b3)
Risk Level: Medium
A vulnerability exists in Apache httpd servers that allow an attacker to
increase the load average on the machine. When an attacker sends
excessive http requests with thousands of '/'s inside, the system running
the server slows down effectively denying service. This problem has a
patch and will be corrected in 1.2.5 release.

___
Date Reported: 12/24/97
Vulnerability: quake2-dos
Platforms Affected: Windows Machines running Quake 2 Server
Risk Level: Low
Quake 2 servers have a vulnerability that allows a remote attacker to shut
down the server. By sending a couple of spoofed UDP packets with a return
address of 127.0.0.1 or a return address of another Quake 2 server to the
machine running server, the it will then try to start a game with itself,
and crash.

___
Date Reported: 12/15/97
Vulnerability: cisco-7xxcrash
Platforms Affected: Cisco 7xx routers (IOS 700 4.1(1), 4.1(2),
or 4.1 interim releases earlier than 4.1(2.1))
Risk Level: High
Cisco 7xx routers running IOS 700 are vulnerable to a denial of service
attack that reboots the router. An attacker can telnet to the router, and
enter a very long password string that overflows the data buffer that
is used for passwords. This forces the router to crash denying service to
legitimate users.

Update: sun-pentium
Vendor: Sun Microsystems, Inc.
Platforms: Pentium machines running Solaris
(2.4, 2.5 , 2.5.1, 2.6)
Sun has released patches for its Solaris Intel platforms for the Intel

___
Risk Factor Key:
High any vulnerability that provides an attacker with immediate
access into a machine, gains superuser access, or bypasses
a firewall. Example: A vulnerable Sendmail 8.6.5 version
that allows an intruder to execute commands on mail
server.
Medium any vulnerability that provides information that has a
high potential of giving access to an intruder. Example:
A misconfigured TFTP or vulnerable NIS server that allows
an intruder to get the password file that possibly can
contain an account with a guessable password.
Low any vulnerability that provides information that
potentially could lead to a compromise. Example: A
finger that allows an intruder to find out who is online
and potential accounts to attempt to crack passwords
via bruteforce.
