Category:	Debian Local Security Checks
Title:	Debian: Security Advisory (DLA-2841-1)
Summary:	The remote host is missing an update for the Debian 'runc' package(s) announced via the DLA-2841-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'runc' package(s) announced via the DLA-2841-1 advisory. Vulnerability Insight: It was discovered that there was an overflow issue in runc, the runtime for the Open Container Project, often used with Docker. The Netlink 'bytemsg' length field could have allowed an attacker to override Netlink-based container configurations. This vulnerability required the attacker to have some control over the configuration of the container, but would have allowed the attacker to bypass the namespace restrictions of the container by simply adding their own Netlink payload which disables all namespaces. CVE-2021-43784 For Debian 9 Stretch, these problems have been fixed in version 0.1.1+dfsg1-2+deb9u3. We recommend that you upgrade your runc packages.

Solution: Please install the updated package(s). CVSS Score: 6.0 CVSS Vector: AV:N/AC:M/Au:S/C:P/I:P/A:P
