CVE-2018-16875: Golang Go

High severity, CVSS 7.5. EPSS: 6.4% chance of exploitation in the next 30 days.

The crypto/x509 package of Go before 1.10.6 and 1.11.x before 1.11.3 does not limit the amount of work performed for each chain verification, which might allow attackers to craft pathological inputs leading to a CPU denial of service. Go TLS servers accepting client certificates and TLS clients are affected.

Affected products

• Golang Go: before 1.10.6 (fixed in 1.10.6); from 1.11.0, before 1.11.3 (fixed in 1.11.3)
• Opensuse Leap: version 42.3 only
