Description

The tls_decrypt_ticket function in ssl/t1_lib.c in OpenSSL before 1.1.0 does not consider the HMAC size during validation of the ticket length, which allows remote attackers to cause a denial of service via a ticket that is too short.

Solution(s)

  • http-openssl-1_0_1-upgrade-1_0_1_u
  • http-openssl-1_0_2-upgrade-1_0_2_i
