The cnonce (client nonce) is generated from an MD5 hash of the PID, the epoch time and the built-in rand function. The PID comes from a small set of numbers, and the epoch time may be guessed if not leaked from the HTTP Date header. The built-in rand function is unsuitable for cryptographic usage. According to RFC 2831, the cnonce-value should be provided by the client and contain at least 64 bits of entropy to ensure security.(CVE-2025-40918)","affected":[{"package":{"ecosystem":"openEuler:24.03-LTS-SP3","name":"perl-Authen-SASL","purl":"pkg:rpm/openEuler/perl-Authen-SASL&distro=openEuler-24.03-LTS-SP3"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.1700-2.oe2403sp3"}]}],"ecosystem_specific":{"noarch":["perl-Authen-SASL-2.1700-2.oe2403sp3.noarch.rpm","perl-Authen-SASL-help-2.1700-2.oe2403sp3.noarch.rpm"],"src":["perl-Authen-SASL-2.1700-2.oe2403sp3.src.rpm"]}}],"references":[{"type":"ADVISORY","url":"https://www.openeuler.org/zh/security/security-bulletins/detail/?id=openEuler-SA-2026-2423"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-40918"}],"database_specific":{"severity":"Medium"}}
