Debian DSA-393-1 : openssl - denial of service

medium Nessus Plugin ID 15230

Synopsis

The remote Debian host is missing a security-related update.

Description

Dr. Stephen Henson (), using a test suite provided by NISCC (), discovered a number of errors in the OpenSSL ASN1 code. Combined with an error that causes the OpenSSL code to parse client certificates even when it should not, these errors can cause a denial of service (DoS) condition on a system using the OpenSSL code, depending on how that code is used. For example, even though apache-ssl and ssh link to OpenSSL libraries, they should not be affected by this vulnerability.
However, other SSL-enabled applications may be vulnerable and an OpenSSL upgrade is recommended.

Solution

For the current stable distribution (woody) these problems have been fixed in version 0.9.6c-2.woody.4.

We recommend that you update your openssl package. Note that you will need to restart services which use the libssl library for this update to take effect.
