Description Tim Sammut (RETIRED) gentoo-dev 2012-05-10 23:42:15 UTC
From the upstream advisory at $URL:

OpenSSL Security Advisory [10 May 2012]

Invalid TLS/DTLS record attack (CVE-2012-2333)

A flaw in the OpenSSL handling of CBC mode ciphersuites in TLS 1.1, 1.2 and
DTLS can be exploited in a denial of service attack on both clients and

DTLS applications are affected in all versions of OpenSSL. TLS is only
affected in OpenSSL 1.0.1 and later.

Thanks to Codenomicon for discovering this issue using Fuzz-o-Matic fuzzing
as a service testing platform.

The fix was developed by Stephen Henson of the OpenSSL core team.

Affected users should upgrade to OpenSSL 1.0.1c, 1.0.0j or 0.9.8x

CVE-2012-2333 (
  Integer underflow in OpenSSL before 0.9.8x, 1.0.0 before 1.0.0j, and 1.0.1
  before 1.0.1c, when TLS 1.1, TLS 1.2, or DTLS is used with CBC encryption,
  allows remote attackers to cause a denial of service (buffer over-read) or
  possibly have unspecified other impact via a crafted TLS packet that is not
  properly handled during a certain explicit IV calculation.
