Description Vincent Danen 2014-01-06 21:53:58 UTC
A flaw was found in the way OpenSSL handled TLS handshakes.  A carefully crafted invalid TLS handshake could crash OpenSSL with a NULL pointer exception.

This flaw only affects OpenSSL versions 1.0.1 through 1.0.1e; earlier versions are not affected and this is corrected in upstream version 1.0.1f [1],[2].

Comment 2 Vincent Danen 2014-01-06 22:03:06 UTC
Created openssl tracking bugs for this issue:

Affects: fedora-all [bug 1049061]

Comment 3 Vincent Danen 2014-01-06 22:03:08 UTC
Created mingw-openssl tracking bugs for this issue:

Affects: fedora-all [bug 1049062]

Comment 6 Tomas Hoger 2014-01-07 16:02:22 UTC
This is a client side issue - an application using OpenSSL library to implement TLS/SSL client functionality can be crashed by malicious TLS/SSL server (or MITM attacker tampering with handshake packets) using this flaw.

Affected code was introduced when Next Protocol Negotiation support was added in version 1.0.1.  Relevant upstream commit:

http://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff;h=ee2ffc2

Therefore, only versions 1.0.1 are affected by this issue.  The openssl packages in Red Hat Enterprise Linux 5 and earlier are not affected (they are based on older 0.9.* versions).  The openssl packages in Red Hat Enterprise Linux 6 before 6.5 were also not affected, as they were based on upstream version 1.0.0.  They were updated to version 1.0.1e in Red Hat Enterprise Linux 6.5 via RHBA-2013:1585.

Statement:

This issue did not affect the versions of openssl as shipped with Red Hat Enterprise Linux 5 and earlier.
