Debian GNU/Linux Advisory: openssl094, openssl095, openssl

Debian Security Advisory DSA-136-2                                     Michael Stone
September 15, 2002          
- ------------------------------------------------------------------------

Package        : openssl094, openssl095, openssl
Problem type   : multiple remote exploits
Debian-specific: no
CVE            : CAN-2002-0655 CAN-2002-0656 CAN-2002-0657 CAN-2002-0659

Note: this advisory is an update to DSA-136-1, issued 30 Jul 2002. It
includes ASN1 updates in the woody packages, plus the potato packages
which were not initially available.

The OpenSSL development team has announced that a security audit by A.L.
Digital Ltd and The Bunker, under the DARPA CHATS program, has revealed
remotely exploitable buffer overflow conditions in the OpenSSL code.
Additionaly, the ASN1 parser in OpenSSL has a potential DoS attack
independently discovered by Adi Stav and James Yonan.

CAN-2002-0655 references overflows in buffers used to hold ASCII
representations of integers on 64 bit platforms. CAN-2002-0656
references buffer overflows in the SSL2 server implementation (by
sending an invalid key to the server) and the SSL3 client implementation
(by sending a large session id to the client). The SSL2 issue was also
noticed by Neohapsis, who have privately demonstrated exploit code for
this issue. CAN-2002-0659 references the ASN1 parser DoS issue.

These vulnerabilities have been addressed for Debian 3.0 (woody) in
openssl094_0.9.4-6.woody.1, openssl095_0.9.5a-6.woody/.1 and

These vulnerabilities are also present in Debian 2.2 (potato). Fixed
packages are available in openssl094_0.9.4-6.potato/.0 and

Only i386 packages for openssl094 and openssl095 are available at this
time; other architectures will be made available as soon as possible.

A worm is actively exploiting this issue on internet-attached hosts;
we recommend you upgrade your OpenSSL as soon as possible. Note that you
must restart any daemons using SSL. (E.g., ssh or ssl-enabled apache.)
If you are uncertain which programs are using SSL you may choose to
reboot to ensure that all running daemons are using the new libraries.

- ------------------------------------------------------------------------

Obtaining updates:

  By hand:
    wget URL
        will fetch the file for you.
    dpkg -i FILENAME.deb
        will install the fetched file.

  With apt:
    deb stable/updates main
        added to /etc/apt/sources.list will provide security updates

Additional information can be found on the Debian security webpages
