Remote exploitation of a memory leak in the Apache HTTP Server causes the daemon to over utilize system resources on an affected system.
Summary
- - ---------------------------------------------------------------------
GENTOO LINUX SECURITY ANNOUNCEMENT 200304-01
- - ---------------------------------------------------------------------
FIXED VERSION : >=2.0.45
- - ---------------------------------------------------------------------
- From advisory:
"Remote exploitation of a memory leak in the Apache HTTP Server causes the
daemon to over utilize system resources on an affected system. The problem
is HTTP Server's handling of large chunks of consecutive linefeed
characters. The web server allocates an eighty-byte buffer for each
linefeed character without specifying an upper limit for allocation.
Consequently, an attacker can remotely exhaust system resources by
generating many requests containing these characters."
