Description

ssl/s3_clnt.c in OpenSSL 1.0.0 before 1.0.0t, 1.0.1 before 1.0.1p, and 1.0.2 before 1.0.2d, when used for a multi-threaded client, writes the PSK identity hint to an incorrect data structure, which allows remote servers to cause a denial of service (race condition and double free) via a crafted ServerKeyExchange message.

Solution(s)

  • http-openssl-1_0_0-upgrade-1_0_0_t
  • http-openssl-1_0_1-upgrade-1_0_1_p
  • http-openssl-1_0_2-upgrade-1_0_2_d
