Summary

GNU TLS is vulnerable to a denial-of-service (DoS) due to inefficient certificate processing in the libtasn1 library. An attacker could present a maliciously crafted certificate that contains a large amount of subject alternative name or name constraint inputs, potentially leading to excessive resource consumption which could cause a denial-of-service.
