Description

A process running under a restrictive seccomp filter that specified multiple syscall arguments could bypass intended access restrictions by specifying a single matching argument.

Additionally, runc has been rebuilt with the fixed package.

For Debian 9 stretch, this problem has been fixed in version 0.0~git20150813.0.1b506fc-2+deb9u1.

We recommend that you upgrade your golang-github-seccomp-libseccomp-golang and runc packages, and recompile own Go code using golang-github-seccomp-libseccomp-golang.

For the detailed security status of golang-github-seccomp-libseccomp-golang please refer to its security tracker page at: https://security-tracker.debian.org/tracker/golang-github-seccomp-libs eccomp-golang

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
