### Impact There is an ext4 use-after-free flaw described in CVE-2022-1184 that is exploitable through versions of Apptainer < 1.1.0, installations that include apptainer-suid < 1.1.8, and all versions of Singularity in their default configurations 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. ### Background Historically there have been many CVEs published for extfs and a smaller number for squashfs, including serious use-after-free and buffer overrun vulnerabilities, that are scored as "Moderate" or "Low" impact only because unprivileged users were assumed to not have write access to the raw data. Because of those ratings, vendors treat such CVEs as low urgency and either delay a patch u...

Ubuntu Security Notice 6038-1 - It was discovered that the Go net/http module incorrectly handled Transfer-Encoding headers in the HTTP/1 client. A remote attacker could possibly use this issue to perform an HTTP Request Smuggling attack. It was discovered that Go did not properly manage memory under certain circumstances.

Ubuntu Security Notice 6040-1 - It was discovered that the Traffic-Control Index implementation in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the OverlayFS implementation in the Linux kernel did not properly handle copy up operation in some conditions. A local attacker could possibly use this to gain elevated privileges.
