Descriptions
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.
Múltiples fugas de memoria en t1_lib.c en OpenSSL en versiones anteriores a 1.0.1u, 1.0.2 en versiones anteriores a 1.0.2i y 1.1.0 en versiones anteriores a 1.1.0a permiten a atacantes remotos provocar una denegación de servicio (consumo de memoria) a través de grandes extensiones OCSP Status Request
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.
Double-free and invalid-free vulnerabilities in x509 parsing were found in the latest OpenSSL (1.1.0b).
