CVE-2004-2531

X.509 certificate verification in GnuTLS 1.0.16 can be exploited by sending RSA certificates with very large modulus/exponent values to cause resource exhaustion and a denial of service. The CERT advisory notes cross‑vendor impact and that patches/updates have been released by vendors; apply the ...
