NVD Description

Note: Versions mentioned in the description apply only to the upstream openssl-perl package and not the openssl-perl package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

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.
