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
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-201706-21 (nettle: Information disclosure)
It was found that nettle’s RSA and DSA decryption code was vulnerable to cache-related side channel attacks.
See the referenced technical paper “Cache Attacks Enable Bulk Key Recovery on the Cloud” below for details.
An attacker could recover the private key from a co-located virtual-machine instance.
There is no known workaround at this time.
SolutionAll nettle users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=dev-libs/nettle-3.2-r1'
