DEBIAN-CVE-2026-50721

Libreswan, via the function RSAauthenticatehashsignaturerawrsa, did not correctly verify the length of the authentication hash when the SIG payload of an IKEv1 packet was encoded using PKCS 1 RSA Encryption as per RFC 2313. A remote attacker can use a variation on the Bleichenbacher attack to for...

CVE-2026-50722

Libreswan is affected by CVE-2026-50722 through RSA_authenticate_hash_signature_pkcs1_1_5_rsa, which fails to properly verify the DER encoding of the ASN.1 digest when the IKEv2 AUTH payload uses RSASSA-PKCS1-v1_5 (RFC 8017). This enables a remote attacker to perform a Bleichenbacher-like variati...

CVE-2026-50722

Libreswan, via the function RSAauthenticatehashsignaturepkcs115rsa, did not correctly verify the DER encoding of the ASN.1 digest when the IKEv2 AUTH payload was encoded using RSASSA-PKCS1-v15 RFC 8017. A remote attacker can use a variation on the Bleichenbacher attack to forge the AUTH payload...

CVE-2026-12413

An invalidly formatted IKEv2 fragment causes the Libreswan pluto daemon to crash and restart. Continued exploitation would cause a denial of service. The function reassemblev2incomingfragments would ignore unknown outer payloads but still store these in a fixed size array msgdigest.digestPAYLIMIT...

CVE-2026-59096

Dapr Sentry’s OIDC discovery endpoint can be poisoned: the issuer and jwks_uri in /.well-known/openid-configuration are derived from the request Host via an attacker-controlled X-Forwarded-Host when oidc-allowed-hosts is not configured, and the document is cached for one hour. This allows remote ...
