CVE-2019-9893: Dependency on vulnerable version of libseccomp | Cloud Foundry

Severity

Critical

The libseccomp Project

Affected Cloud Foundry Products and Versions

  • All versions prior to v11.0.0

Description

libseccomp before 2.4.0 did not correctly generate 64-bit syscall argument comparisons using the arithmetic operators (LT, GT, LE, GE), which might able to lead to bypassing seccomp filters and potential privilege escalations.

• cf-deployment
  • Upgrade All versions to v11.0.0 or greater
