Moderate: rust-cargo-c security update (Amazon Linux 2023)

Published Mar 30, 2026 · Updated Apr 1, 2026

Summary

Package updates are available for Amazon Linux 2023 that fix the following vulnerabilities: CVE-2026-25727: time provides date and time handling in Rust. From 0.3.6 to before 0.3.47, when user-provided input is provided to any type that parses with the RFC 2822 format, a denial of service attack via stack exhaustion is possible. The attack relies on formally deprecated and rarely-used features that are part of the RFC 2822 format used in a malicious manner. Ordinary, non-malicious input will never encounter this scenario. A limit to the depth of recursion was added in v0.3.47. From this version, an error will be returned rather than exhausting the stack. CVE-2026-0810: A flaw in the gix-date library can generate invalid non-UTF8 strings, leading to undefined behavior when processed. The most likely impact from a successful attack is to data integrity, by the malicious data being able to corrupt data being hold in memory and to system availability as it eventually may lead to the software using the gix_date library to crash.
