Updated openssl packages fix security vulnerabilities

Updated openssl packages fix security vulnerabilities: The function ASN1TYPEcmp will crash with an invalid read if an attempt is made to compare ASN.1 boolean types. Since ASN1TYPEcmp is used to check certificate signature algorithm consistency this can be used to crash any certificate verificati...

Vulnerability in OpenSSL - Use After Free following d2i_ECPrivatekey error

Use After Free following d2iECPrivatekey error. A malformed EC private key file consumed via the d2iECPrivateKey function could cause a use after free condition. This, in turn, could cause a double free in several private key parsing functions such as d2iPrivateKey or EVPPKCS82PKEY and could lead...

Race condition

Race condition in the sslparseserverhellotlsext function in t1lib.c in OpenSSL 1.0.0 before 1.0.0n and 1.0.1 before 1.0.1i, when multithreading and session resumption are used, allows remote SSL servers to cause a denial of service memory overwrite and client application crash or possibly have...

CVE-2014-3509

CVE-2014-3511 affects OpenSSL 1.0.1 before 1.0.1i. It describes a protocol-downgrade vulnerability where a Man-in-the-Middle can force the use of TLS 1.0 by triggering ClientHello fragmentation in communications that support later TLS versions. The consequence is potential downgrade of security d...
