Fedora 42 bustle Moderate Denial Of Service CVE-2026-25537 Advisory

fedora
Calendar Grey February 11, 2026
Dist Fedora Esm H88
Update bustle on Fedora 42 to fix stack exhaustion DoS and potential authorization bypass issues. Essential security patch.
Update the time crate to version 0.3.47

Summary

Bustle draws sequence diagrams of D-Bus activity, showing signal

emissions, method calls and their corresponding returns, with timestamps

for each individual event and the duration of each method call. This can

help you check for unwanted D-Bus traffic, and pinpoint why your

D-Bus-based application isn't performing as well as you like. It also

provides statistics like signal frequencies and average method call

times.

Update Information:

Update the time crate to version 0.3.47. Update the time-macros crate to version 0.2.27. Update the time-core crate to version 0.1.8. Update the num-conv crate to version 0.2.0. Update the git2 crate to version 0.20.4. Update the bytes crate to version 1.11.1. Additionally, this update contains rebuilds of applications affected by security advisories: bytes: RUSTSEC-2026-0007 git2: RUSTSEC-2026-0008 jsonwebtoken: CVE-2026-25537 time: RUSTSEC-2026-0009 All applications that statically link libgit2 via the git2 Rust bindings were also rebuilt against the latest version of the git2 / libgit2-sys crates to pull in fixes included in libgit2 between v1.8.1 and v1.9.2.
