EM64T local DoS

Unspecified vulnerability in the "stack unwinder fixes" in kernel in Red Hat Enterprise Linux 5, when running on AMD64 and Intel 64, allows local users to cause a denial of service via unknown vectors.

kernel: ptrace: Unprivileged crash on x86_64 %cs corruption

Linux kernel 2.6.18, and possibly other versions, when running on AMD64 architectures, allows local users to cause a denial of service (crash) via certain ptrace calls.

The kernel in FreeBSD 6.3 through 7.0 on amd64 platforms can make an extra swapgs call after a General Protection Fault (GPF), which allows local users to gain privileges by triggering a GPF during the kernel's return from (1) an interrupt, (2) a trap, or (3) a system call.

FreeBSD 5.x to 5.4 on AMD64 does not properly initialize the IO permission bitmap used to allow user access to certain hardware, which allows local users to bypass intended access restrictions to cause a denial of service, obtain sensitive information, and possibly gain privileges.

Access policy with access to all tenants and using label selectors has more access

A vulnerability in the label-based access control of Grafana Labs Grafana Enterprise Metrics allows an attacker more access than intended. If an access policy which has label selector restrictions also has been granted access to all tenants in the system, the label selector restrictions will not be applied when using this policy with the affected versions of the software. This issue affects: Grafana Labs Grafana Enterprise Metrics GEM 1.X versions prior to 1.7.1 on AMD64; GEM 2.X versions prior to 2.3.1 on AMD64.
