Vulnerability Assessment Details

[DSA393] DSA-393-1 openssl

Vulnerability Assessment Summary
DSA-393-1 openssl

Detailed Explanation for this Vulnerability Assessment

Dr. Stephen Henson ("steve@openssl.org"), using a test suite
provided by NISCC ("http://www.niscc.gov.uk/"), 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.
For the current stable distribution (woody) these problems have been
fixed in version 0.9.6c-2.woody.4.
For the unstable distribution (sid) these problems have been fixed in
version 0.9.7c-1.
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.
