Description Mark J. Cox 2004-11-04 11:44:15 UTC 
An issue was discovered where the field length limit was not enforced
for certain malicious requests. This could allow a remote attacker who
is able to send large amounts of data to a server the ability to cause
Apache children to consume proportional amounts of memory, leading to
a denial of service.

Affects: 2.0.52, 2.0.51, 2.0.50, 2.0.49, 2.0.48, 2.0.47, 2.0.46,
2.0.45, 2.0.44, 2.0.43, 2.0.42, 2.0.40, 2.0.39, 2.0.37, 2.0.36, 2.0.35

Comment 3 Ivan Baldo 2004-11-22 21:23:26 UTC 
It is exploitable in Fedora Core 1 too and fedoralegacy.org doesn't
have an update yet (2.0.51-1.4.legacy).
