CVSS: 6.1EPSS: 0%CPEs: 2EXPL: 0CVE-2023-38496 – Apptainer's ineffective privileges drop when requesting container network
https://notcve.org/view.php?id=CVE-2023-38496
Apptainer is an open source container platform. Version 1.2.0-rc.2 introduced an ineffective privilege drop when requesting container network setup, therefore subsequent functions are called with root privileges, the attack surface is rather limited for users but an attacker could possibly craft a starter config to delete any directory on the host filesystems. A security fix has been included in Apptainer 1.2.1. There is no known workaround outside of upgrading to Apptainer 1.2.1. • https://github.com/apptainer/apptainer/pull/1523 https://github.com/apptainer/apptainer/pull/1578 https://github.com/apptainer/apptainer/security/advisories/GHSA-mmx5-32m4-wxvx • CWE-269: Improper Privilege Management CWE-271: Privilege Dropping / Lowering Errors •
CVSS: 7.8EPSS: 0%CPEs: 3EXPL: 0CVE-2023-30549 – Unpatched extfs vulnerabilities are exploitable through suid-mode Apptainer
https://notcve.org/view.php?id=CVE-2023-30549
Apptainer is an open source container platform for Linux. There is an ext4 use-after-free flaw that is exploitable through versions of Apptainer < 1.1.0 and installations that include apptainer-suid < 1.1.8 on older operating systems where that CVE has not been patched. That includes Red Hat Enterprise Linux 7, Debian 10 buster (unless the linux-5.10 package is installed), Ubuntu 18.04 bionic and Ubuntu 20.04 focal. Use-after-free flaws in the kernel can be used to attack the kernel for denial of service and potentially for privilege escalation. Apptainer 1.1.8 includes a patch that by default disables mounting of extfs filesystem types in setuid-root mode, while continuing to allow mounting of extfs filesystems in non-setuid "rootless" mode using fuse2fs. Some workarounds are possible. Either do not install apptainer-suid (for versions 1.1.0 through 1.1.7) or set `allow setuid = no` in apptainer.conf. • https://access.redhat.com/security/cve/cve-2022-1184 https://github.com/apptainer/apptainer/commit/5a4964f5ba9c8d89a0e353b97f51fd607670a9f7 https://github.com/apptainer/apptainer/releases/tag/v1.1.8 https://github.com/apptainer/apptainer/security/advisories/GHSA-j4rf-7357-f4cg https://github.com/torvalds/linux/commit/2220eaf90992c11d888fe771055d4de3303 https://github.com/torvalds/linux/commit/4f04351888a83e595571de672e0a4a8b74f https://lwn.net/Articles/932136 https://lwn.net/Articles/932137 https://security-tracker.debi • CWE-416: Use After Free •
