openssl096

Multiple vulnerabilities have been discovered in the OpenSSL
cryptographic software package that could allow an attacker to launch
a denial of service attack by exhausting system resources or crashing
processes on a victim’s computer.

• CVE-2006-3738
  Tavis Ormandy and Will Drewry of the Google Security Team
  discovered a buffer overflow in SSL_get_shared_ciphers utility
  function, used by some applications such as exim and mysql. An
  attacker could send a list of ciphers that would overrun a
  buffer.
• CVE-2006-4343
  Tavis Ormandy and Will Drewry of the Google Security Team
  discovered a possible DoS in the sslv2 client code. Where a
  client application uses OpenSSL to make a SSLv2 connection to
  a malicious server that server could cause the client to
  crash.
• CVE-2006-2940
  Dr S N Henson of the OpenSSL core team and Open Network
  Security recently developed an ASN1 test suite for NISCC
  (www.niscc.gov.uk). When the test suite was run against
  OpenSSL a DoS was discovered.

Certain types of public key can take disproportionate amounts
of time to process. This could be used by an attacker in a
denial of service attack.

For the stable distribution (sarge) these problems have been fixed in
version 0.9.6m-1sarge4.

This package exists only for compatibility with older software, and is
not present in the unstable or testing branches of Debian.

We recommend that you upgrade your openssl096 package. Note that
services linking against the openssl shared libraries will need to be
restarted. Common examples of such services include most Mail
Transport Agents, SSH servers, and web servers.
