OpenSSL 0.9.6e < 0.9.6f Vulnerability

high Nessus Plugin ID 17747

Language:

Synopsis

The remote service is affected by a vulnerability.

Description

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

- OpenSSL 0.9.6e uses assertions when detecting buffer overflow attacks instead of less severe mechanisms, which allows remote attackers to cause a denial of service (crash) via certain messages that cause OpenSSL to abort from a failed assertion, as demonstrated using SSLv2 CLIENT_MASTER_KEY messages, which are not properly handled in s2_srvr.c. (CVE-2002-1568)

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 0.9.6f or later.
