According to the versions of the docker-runc package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :
runc is a CLI tool for spawning and running containers on Linux according to the OCI specification. In runc 1.1.11 and earlier, due to an internal file descriptor leak, an attacker could cause a newly-spawned container process (from runc exec) to have a working directory in the host filesystem namespace, allowing for a container escape by giving access to the host filesystem ('attack 2'). The same attack could be used by a malicious image to allow a container process to gain access to the host filesystem through runc run ('attack 1'). Variants of attacks 1 and 2 could be also be used to overwrite semi-arbitrary host binaries, allowing for complete container escapes ('attack 3a' and 'attack 3b'). runc 1.1.12 includes patches for this issue. (CVE-2024-21626)
Tenable has extracted the preceding description block directly from the EulerOS docker-runc security advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
