Description Tomas Hoger 2010-03-24 14:30:01 UTC

New OpenSSL upstream version 0.9.8n fixes a security issue detailed in the upstream "Record of death" vulnerability security advisory:

  http://marc.info/?l=openssl-dev&m=126943908131206&w=2

  In TLS connections, certain incorrectly formatted records can cause an
  OpenSSL client or server to crash due to a read attempt at NULL.

  Affected versions depend on the C compiler used with OpenSSL:

  - If 'short' is a 16-bit integer, this issue applies only to OpenSSL 0.9.8m.
  - Otherwise, this issue applies to OpenSSL 0.9.8f through 0.9.8m.

  Users of OpenSSL should update to the OpenSSL 0.9.8n release, which contains
  a patch to correct this issue.  If upgrading is not immediately possible,
  the source code patch provided in this advisory should be applied.

  Bodo Moeller and Adam Langley (Google) have identified the vulnerability
  and prepared the fix.

Comment 1 Tomas Hoger 2010-03-24 17:26:42 UTC

This issue did not affect openssl packages in Red Hat Enterprise Linux 3, 4 and 5.

Th size of 'short' is 16-bit on all platforms on which Red Hat Enterprise Linux is supported.  Upstream version 0.9.8m was submitted as an update to Fedora 11, but has not been pushed to stable yet.  1.0.0-beta versions are reportedly affected too.
