OpenSSL 0.9.6 < 0.9.6i Vulnerability

medium Nessus Plugin ID 200207

Language:

Synopsis

The remote service is affected by a vulnerability.

Description

The version of OpenSSL installed on the remote host is prior to 0.9.6i. It is, therefore, affected by a vulnerability as referenced in the 0.9.6i advisory.

 - ssl3_get_record in s3_pkt.c for OpenSSL before 0.9.7a and 0.9.6 before 0.9.6i does not perform a MAC computation if an incorrect block cipher padding is used, which causes an information leak (timing discrepancy) that may make it easier to launch cryptographic attacks that rely on distinguishing between padding and MAC verification errors, possibly leading to extraction of the original plaintext, aka the Vaudenay timing attack. (CVE-2003-0078)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to OpenSSL version 0.9.6i or later.
