NVD Description
Note: Versions mentioned in the description apply only to the upstream openssl package and not the openssl package as distributed by RHEL.
See How to fix? for RHEL:7 relevant fixed versions and status.
Multiple memory leaks in t1_lib.c in OpenSSL before 1.0.1u, 1.0.2 before 1.0.2i, and 1.1.0 before 1.1.0a allow remote attackers to cause a denial of service (memory consumption) via large OCSP Status Request extensions.
