Description

The dtls1_clear_queues function in ssl/d1_lib.c in OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h frees data structures without considering that application data can arrive between a ChangeCipherSpec message and a Finished message, which allows remote DTLS peers to cause a denial of service (memory corruption and application crash) or possibly have unspecified other impact via unexpected application data.

Solution(s)

  • http-openssl-0_9_8-upgrade-0_9_8_z_a
  • http-openssl-1_0_0-upgrade-1_0_0_m
  • http-openssl-1_0_1-upgrade-1_0_1_h
