openssl vulnerabilities

Published Mar 19, 2015 · Updated Apr 22, 2026

Summary

It was discovered that OpenSSL incorrectly handled malformed EC private key
files. A remote attacker could possibly use this issue to cause OpenSSL to
crash, resulting in a denial of service, or execute arbitrary code.
(CVE-2015-0209)

Stephen Henson discovered that OpenSSL incorrectly handled comparing ASN.1
boolean types. A remote attacker could possibly use this issue to cause
OpenSSL to crash, resulting in a denial of service. (CVE-2015-0286)

Emilia Käsper discovered that OpenSSL incorrectly handled ASN.1 structure
reuse. A remote attacker could possibly use this issue to cause OpenSSL to
crash, resulting in a denial of service, or execute arbitrary code.
(CVE-2015-0287)

Brian Carpenter discovered that OpenSSL incorrectly handled invalid
certificate keys. A remote attacker could possibly use this issue to cause
OpenSSL to crash, resulting in a denial of service. (CVE-2015-0288)

Michal Zalewski discovered that OpenSSL incorrectly handled missing outer
ContentInfo when parsing PKCS#7 structures. A remote attacker could
possibly use this issue to cause OpenSSL to crash, resulting in a denial of
service, or execute arbitrary code. (CVE-2015-0289)

Robert Dugal and David Ramos discovered that OpenSSL incorrectly handled
decoding Base64 encoded data. A remote attacker could possibly use this
issue to cause OpenSSL to crash, resulting in a denial of service, or
execute arbitrary code. (CVE-2015-0292)

Sean Burford and Emilia Käsper discovered that OpenSSL incorrectly handled
specially crafted SSLv2 CLIENT-MASTER-KEY messages. A remote attacker could
possibly use this issue to cause OpenSSL to crash, resulting in a denial of
service. (CVE-2015-0293)
