All supported architectures
Several security vulnerabilities have been fixed in the latest release of
The Apache HTTP Server Project is an effort to develop and maintain an
open-source HTTP server for modern operating systems. The goal of this
project is to provide a secure, efficient and extensible server that
provides services in tune with the current HTTP standards.
On 64-bit big-endian platforms, mod_access does not properly parse
Allow/Deny rules using IP addresses without a netmask which could result in
failure to match certain IP addresses.
Terminal escape sequences are not filtered from error logs. This could be
used by an attacker to insert escape sequences into a terminal emulater
vulnerable to escape sequences.
mod_digest does not properly verify the nonce of a client response by using
a AuthNonce secret. This could permit an attacker to replay the response of
another website. This does not affect mod_auth_digest.
On certain platforms there is a starvation issue where listening sockets
fails to handle short-lived connection on a rarely-accessed listening
socket. This causes the child to hold the accept mutex and block out new
connections until another connection arrives on the same rarely-accessed
listening socket thus leading to a denial of service.
These vulnerabilities could lead to attackers bypassing intended access
restrictions, denial of service, and possibly execution of arbitrary code.
There is no known workaround at this time.
All users should upgrade to the latest stable version of Apache 1.3.
