Severity
Medium
Vendor
dpkg
Versions Affected
- Ubuntu 14.04
Description
Hanno Boeck discovered that the dpkg-deb tool incorrectly handled certain old style Debian binary packages. If a user or an automated system were tricked into unpacking a specially crafted binary package, a remote attacker could possibly use this issue to execute arbitrary code.
The Cloud Foundry project released a BOSH stemcell version 3145 that has the patched version of the Linux kernel. A new Cloud Foundry rootfs was also released, cflinuxfs2 v.1.20.0, that has the patches.
Affected Products and Versions
Severity is medium unless otherwise noted.
- All versions of Cloud Foundry BOSH stemcells prior to 3145 are vulnerable.
- All versions of Cloud Foundry cflinuxfs2 prior to v.1.20.0.
Mitigation
Users of affected versions should apply the following mitigation:
- The Cloud Foundry project recommends that Cloud Foundry deployments run with BOSH stemcells 3145 or later versions and cflinuxfs2 v.1.20.0 or later versions.
