Package : apache-ssl
Problem type : remote DoS / exploit
Debian-specific: no
CVE name : CAN-2002-0392
CERT advisory : VU#944335
Mark Litchfield found a denial of service attack in the Apache
web-server. While investigating the problem the Apache Software
Foundation discovered that the code for handling invalid requests which
use chunked encoding also might allow arbitrary code execution on 64 bit
architectures.
This has been fixed in version 1.3.9.13-4.1 of the Debian apache-ssl
package and we recommand that you upgrade your apache-ssl package
immediately.
An update for the soon to be released Debian GNU/Linux 3.0/woody
distribution is not available at the moment.
wget url
will fetch the file for you
dpkg -i file.deb
will install the referenced file.
Debian GNU/Linux 2.2 alias potato
- - ---------------------------------
Potato was released for alpha, arm, i386, m68k, powerpc and sparc.
