Fedora 39: Advisory FEDORA-2024-40ee18b2e7 Critical Rust zram generator DoS

fedora
Calendar Grey June 2, 2024
Dist Fedora Esm H88
Fedora 39 enhancements for rust-zram-generator address vulnerabilities in systemd unit generator and swap mechanisms.
This update contains builds from a mini-mass-rebuild for Rust applications (and some C-style libraries)

Summary

This is a systemd unit generator that enables swap on zram.

(With zram, there is no physical swap device. Part of the available RAM

is used to store compressed pages, essentially trading CPU cycles for memory.)

To activate, install zram-generator-defaults subpackage.

Update Information:

This update contains builds from a mini-mass-rebuild for Rust applications (and some C-style libraries). Rebuilding with the Rust 1.78 toolchain should fix incomplete debug information for the Rust standard library (and the resulting low-quality stack traces). Additionally, builds will have picked up fixes for some minor low-priority security and / or safety fixes in crate dependencies that had not yet been handled via a separate (targeted) rebuild: h2 v0.3.26+ (denial-of-service): https://rustsec.org/advisories/RUSTSEC-2024-0332.html glib v0.19.4+ and backports (UB): core/pull/1343 hashbrown v0.14.5+ (UB): https://github.com/rust-lang/hashbrown/pull/511 rustls v0.22.4+, v0.21.11+ (denial-of-service): https://rustsec.org/advisories/RUSTSEC-2024-0336.html
