According to David Wagner, iDEFENSE and the Apache HTTP Server
Project, several vulnerabilities have been found in the Apache
package, a commonly used webserver. Most of the code is shared
between the Apache and Apache-SSL packages, so vulnerabilities are
shared as well. These vulnerabilities could allow an attacker to
enact a denial of service against a server or execute a cross
scripting attack, or steal cookies from other web site users.
Vulnerabilities in the included legacy programs htdigest, htpasswd and
ApacheBench can be exploited when called via CGI. Additionally the
insecure temporary file creation in htdigest and htpasswd can also be
exploited locally. The Common Vulnerabilities and Exposures (CVE)
project identified the following vulnerabilities:
This is the same vulnerability as CAN-2002-1233, which was fixed in
potato already but got lost later and was never applied upstream.
(binaries not included in apache-ssl package though)
6. NO-CAN: Several buffer overflows have been found in the ApacheBench
(ab) utility that could be exploited by a remote server returning
very long strings.
(binary not included in apache-ssl package though)
These problems have been fixed in version 1.3.26.1+1.48-0woody3 for
the current stable distribution (woody) and in 1.3.9.13-4.2 for the
old stable distribution (potato). Corrected packages for the unstable
distribution (sid) are expected soon.
We recommend that you upgrade your Apache-SSL package immediately.
