GHSA-79WF-QCQV-R22R Remote code execution in better-macro

An issue was discovered in the better-macro crate through 2021-07-22 for Rust. It intentionally demonstrates that remote attackers can execute arbitrary code via proc-macros, and otherwise has no legitimate purpose...

OESA-2021-1308 util-linux security update

The util-linux package contains a random collection of files that implements some low-level basic linux utilities. Security Fixes: An integer overflow in util-linux through 2.37.1 can potentially cause a buffer overflow if an attacker were able to use system resources in a way that leads to a lar...

An integer overflow in util-linux through 2.37.1 can potentially cause a buffer overflow if an attacker were able to use system resources in a way that leads to a large number in the /proc/sysvipc/sem file. NOTE: this is unexploitable in GNU C Library environments and possibly in all realistic environments.
