USN-3283-1: rtmpdump vulnerabilities

Severity

Medium

Vendor

Canonical Ubuntu

Versions Affected

  • Canonical Ubuntu 14.04

Description

Dave McDaniel discovered that rtmpdump incorrectly handled certain malformed streams. If a user were tricked into processing a specially crafted stream, a remote attacker could cause rtmpdump to crash, resulting in a denial of service, or possibly execute arbitrary code.

Affected Cloud Foundry Products and Versions

Severity is medium unless otherwise noted.

  • Cloud Foundry BOSH stemcells are vulnerable, including:
    • 3263.x versions prior to 3263.26
    • 3312.x versions prior to 3312.26
    • 3363.x versions prior to 3363.24
    • All other stemcells not listed.
  • All versions of Cloud Foundry cflinuxfs2 prior to 1.119.0

Mitigation

OSS users are strongly encouraged to follow one of the mitigations below:

  • The Cloud Foundry project recommends upgrading the following BOSH stemcells:
    • Upgrade 3263.x versions to 3263.26 or later
    • Upgrade 3312.x versions to 3312.26 or later
    • Upgrade 3363.x versions to 3363.24 or later
    • All other stemcells should be upgraded to the latest version.
  • The Cloud Foundry project recommends that Cloud Foundry deployments run with cflinuxfs2 version 1.119.0 or later.
