Invoking pathological RSA/DSA parameters may cause DoS in golang.org/x/crypto/ssh

golang.org/x/crypto golang.org/x/crypto/ssh; Red Hat Cryostat 4 on RHEL 9; Red Hat Red Hat Enterprise Linux 10; Red Hat Red Hat Enterprise Linux 8

The RSA and DSA public key parsers did not enforce size limits on key parameters. A crafted public key with an excessively large modulus or DSA parameter could cause several minutes of CPU consumption during signature verification. This could be triggered by …

CVE-2026-39835 vor 5 Monaten

Invoking server panic during CheckHostKey/Authenticate in golang.org/x/crypto/ssh

golang.org/x/crypto golang.org/x/crypto/ssh; Red Hat Cryostat 4 on RHEL 9; Red Hat Red Hat Enterprise Linux 10; Red Hat Red Hat Enterprise Linux 8

SSH servers which use CertChecker as a public key callback without setting IsUserAuthority or IsHostAuthority could be caused to panic by a client presenting a certificate. CertChecker now returns an error instead of panicking when these callbacks are nil.
