RUSTSEC-2026-0009: Denial of Service via Stack Exhaustion

| Details | | | --- | --- | | Package | `time` | | Version | `0.3.44` | | URL | https://github.com/time-rs/time/blob/main/CHANGELOG.md#0347-2026-02-05 | | Patched Versions | >=0.3.47 | | Unaffected Versions | <0.3.6 | | Aliases | [CVE-2026-25727](https://nvd.nist.gov/vuln/detail/CVE-2026-25727), [GHSA-r6v5-fh4h-64xc](https://github.com/advisories/GHSA-r6v5-fh4h-64xc) | ## Impact 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. ## Patches 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. ## Workarounds Limiting the length of user input is the simplest way to avoid stack exhaustion, as the amount of the stack consumed would be at most a factor of the length of the input.
