New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 3.6


The remote Gentoo host is missing one or more security-related patches.


The remote host is affected by the vulnerability described in GLSA-200806-08 (OpenSSL: Denial of Service)

Ossi Herrala and Jukka Taimisto of Codenomicon discovered two vulnerabilities:
A double free() call in the TLS server name extension (CVE-2008-0891).
The OpenSSL client code does not properly handle servers that omit the Server Key Exchange message in the TLS handshake (CVE-2008-1672).
Impact :

A remote attacker could connect to a vulnerable server, or entice a daemon to connect to a malicious server, causing a Denial of Service of the daemon in both cases.
Workaround :

There is no known workaround at this time.


All OpenSSL users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-libs/openssl-0.9.8g-r2'
