GHSA-V95C-P5HM-XQ8F Overflow in netlink bytemsg length field allows attacker to override netlink-based container configuration in RunC

Impact In runc, netlink is used internally as a serialization system for specifying the relevant container configuration to the C portion of our code responsible for the based namespace setup of containers. In all versions of runc prior to 1.0.3, the encoder did not handle the possibility of an...

Integer Overflow

github.com/opencontainers/runc is vulnerable to integer overflows. The vulnerability exists in containerlinux.go due to insecure handling of null bytes in mount sources which allows an attacker to bypass the namespace restrictions of the container by adding their ownNetlink payload which disables...

CVE-2021-43784

An integer overflow vulnerability was found in runC. This issue occurs due to an incorrect netlink encoder handling the possibility of an integer overflow in the 16-bit length field for the byte array attribute type. This flaw allows an attacker who can include a large enough malicious byte array...

CVE-2021-43784

CVE-2021-43784 affects runc prior to 1.0.3, where a 16‑bit length field overflow in netlink bytemsg allowed an attacker who can influence container configuration to have the parsed payload override netlink-based container configuration and disable namespaces. Impact: potential namespace bypass by...
