Summary
=======

A vulnerability has been fixed in OpenSSL, which can  be  exploited  by 
malicious people to cause a DoS (Denial  of  Service)  and  potentially 
compromise an application using the library. 

Description
===========

CVE-2010-2939: 

Double free vulnerability in the ssl3_get_key_exchange function in  the 
OpenSSL client (ssl/s3_clnt.c) in OpenSSL  1.0.0a,  0.9.8,  0.9.7,  and 
possibly other versions,  when  using  ECDH,  allows  context-dependent 
attackers to cause a denial of service  (crash)  and  possibly  execute 
arbitrary code via a crafted private key with an invalid  prime.  NOTE: 
some sources refer to this as a use-after-free issue. 

Affected packages:

  Pardus 2009:
    openssl, all before 0.9.8k-29-12
