CVE-2021-35525 (GCVE-0-2021-35525)

Vulnerability from cvelistv5 – Published: 2021-06-28 17:38 – Updated: 2024-08-04 00:40

Summary

PostSRSd before 1.11 allows a denial of service (subprocess hang) if Postfix sends certain long data fields such as multiple concatenated email addresses. NOTE: the PostSRSd maintainer acknowledges "theoretically, this error should never occur ... I'm not sure if there's a reliable way to trigger this condition by an external attacker, but it is a security bug in PostSRSd nevertheless."
