Описание
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.
A memory leak flaw was found in the way OpenSSL handled TLS status request extension data during session renegotiation. A remote attacker could cause a TLS server using OpenSSL to consume an excessive amount of memory and, possibly, exit unexpectedly after exhausting all available memory, if it enabled OCSP stapling support.
Отчет
TLS server applications using OpenSSL versions in Red Hat Enterprise Linux 6 and 7 are only affected if they enable OCSP stapling support. Applications not enabling OCSP stapling support are not affected. Few applications implement OCSP stapling support and typically do not enable it by default.
