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.

Synopsis

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

Description

The remote host is affected by the vulnerability described in GLSA-200710-06 (OpenSSL: Multiple vulnerabilities)

Moritz Jodeit reported an off-by-one error in the SSL_get_shared_ciphers() function, resulting from an incomplete fix of CVE-2006-3738. A flaw has also been reported in the BN_from_montgomery() function in crypto/bn/bn_mont.c when performing Montgomery multiplication.
Impact :

A remote attacker sending a specially crafted packet to an application relying on OpenSSL could possibly execute arbitrary code with the privileges of the user running the application. A local attacker could perform a side channel attack to retrieve the RSA private keys.
Workaround :

There is no known workaround at this time.

Solution

All OpenSSL users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-libs/openssl-0.9.8e-r3'
