CVE-2017-15288: Scala-Lang Scala

High severity, CVSS 7.8. EPSS: 0.3% chance of exploitation in the next 30 days.

The compilation daemon in Scala before 2.10.7, 2.11.x before 2.11.12, and 2.12.x before 2.12.4 uses weak permissions for private files in /tmp/scala-devel/${USER:shared}/scalac-compile-server-port, which allows local users to write to arbitrary class files and consequently gain privileges.

Affected products

  • Scala-Lang Scala: before 2.10.7 (fixed in 2.10.7); from 2.11.0, before 2.11.12 (fixed in 2.11.12); from 2.12.0, before 2.12.4 (fixed in 2.12.4)
