CVE-2023-27561 – runc: volume mount race condition (regression of CVE-2019-19921)
https://notcve.org/view.php?id=CVE-2023-27561
runc through 1.1.4 has Incorrect Access Control leading to Escalation of Privileges, related to libcontainer/rootfs_linux.go. To exploit this, an attacker must be able to spawn two containers with custom volume-mount configurations, and be able to run custom images. NOTE: this issue exists because of a CVE-2019-19921 regression. A flaw was found in runc. An attacker who controls the container image for two containers that share a volume can race volume mounts during container initialization by adding a symlink to the rootfs that points to a directory on the volume. • https://gist.github.com/LiveOverflow/c937820b688922eb127fb760ce06dab9 https://github.com/opencontainers/runc/issues/2197#issuecomment-1437617334 https://github.com/opencontainers/runc/issues/3751 https://lists.debian.org/debian-lts-announce/2023/03/msg00023.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ANUGDBJ7NBUMSUFZUSKU3ZMQYZ2Z3STN https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/DHGVGGMKGZSJ7YO67TGGPFEHBYMS63VF https://lists.fedoraproject.org • CWE-41: Improper Resolution of Path Equivalence CWE-706: Use of Incorrectly-Resolved Name or Reference •
CVE-2022-2990 – buildah: possible information disclosure and modification
https://notcve.org/view.php?id=CVE-2022-2990
